Our 3TX71 Solid State relays function as zero crossing
relays; that means the relay turns on when control volt-
age is present and the Sine wave crosses zero. The relay
is turned off when the control voltage is removed and
load current Sine wave crosses zero. In the case where
the input voltage is DC the relay will turn on immediate-
ly when the input voltage is applied. When the output
voltage is DC the relay will turn off as soon as the input
power is removed. See figure A for AC input/AC output
applications.

Siemens Energy & Automation, Inc. (“Seller”)
Standard Terms and Conditions of Sale (09/01/2001)
General
1. WARRANTY - (a) Seller warrants that on the date of shipment the goods are of the kind and
quality described herein and are free of non-conformities in workmanship and material. This war-
ranty does not apply to goods delivered by Seller but manufactured by others.
(b) Buyer's exclusive remedy for a nonconformity in any item of the goods shall be the repair or
the replacement (at Seller's option) of the item and any affected part of the goods. Seller's obli-
gation to repair or replace shall be in effect for a period of one (1) year from initial operation of
the goods but not more than eighteen (18) months from Seller's shipment of the goods, provided
Buyer has sent written notice within that period of time to Seller that the goods do not conform
to the above warranty. Repaired and replacement parts shall be warranted for the remainder of
the original period of notification set forth above, but in no event less than 12 months from repair
or replacement. At its expense, Buyer shall remove and ship to Seller any such nonconforming
items and shall reinstall the repaired or replaced parts. Buyer shall grant Seller access to the
goods at all reasonable times in order for Seller to determine any nonconformity in the goods.
Seller shall have the right of disposal of items replaced by it. If Seller is unable or unwilling to
repair or replace, or if repair or replacement does not remedy the nonconformity, Seller and Buyer
shall negotiate an equitable adjustment in the contract price, which may include a full refund of
the contract price for the nonconforming goods.
(c) SSELLER HHEREBY DDISCLAIMS AALL OOTHER WWARRANTIES, EEXPRESS OOR IIMPLIED, EEXCEPT TTHAT
OF TTITLE. SSPECIFICALLY, IIT DDISCLAIMS TTHE IIMPLIED WWARRANTIES OOF MMERCHANTABILITY, FFIT-
NESS FFOR AA PPARTICULAR PPURPOSE, CCOURSE OOF DDEALING AAND UUSAGE OOF TTRADE.
(d) Buyer and successors of Buyer are limited to the remedies specified in this article and shall
have no others for a nonconformity in the goods. Buyer agrees that these remedies provide Buyer
and its successors with a minimum adequate remedy and are their exclusive remedies, whether
Buyer's or its successors' remedies are based on contract, warranty, tort (including negligence),
strict liability, indemnity, or any other legal theory, and whether arising out of warranties, repre-
sentations, instructions, installations, or non-conformities from any cause.
(e) Note: This article 1 does not apply to any software which may be furnished by Seller. In such
cases, the attached Software License Addendum applies.
2. PATENTS - Seller shall pay costs and damages finally awarded in any suit against Buyer or
its vendees to the extent based upon a finding that the design or construction of the goods as
furnished infringes a United States patent (except infringement occurring as a result of incorpo-
rating a design or modification at Buyer's request), provided that Buyer promptly notifies Seller of
any charge of infringement, and Seller is given the right at its expense to settle such charge and
to defend or control the defense of any suit based upon such charge. Seller shall have no obliga-
tion hereunder with respect to claims, suits or proceedings, resulting from or related to, in whole
or in part, (i) the use of software or software documentation, (ii) compliance with Buyer's specifi-
cations, (iii) the combination with, or modification of, the goods after delivery by Seller, or (iv) the
use of the goods, or any part thereof, in the practice of a process. THIS ARTICLE SETS FORTH
SELLER'S ENTIRE LIABILITY WITH RESPECT TO PATENTS.
3. PERFORMANCE; DDELAYS - Timely performance by Seller is contingent upon Buyer's supply-
ing to Seller, when needed, all required technical information and data, including drawing
approvals, and all required commercial documentation. If Seller suffers delay in performance due
to any cause beyond its reasonable control, the time of performance shall be extended a period
of time equal to the period of the delay and its consequences. Seller will give to Buyer notice
within a reasonable time after Seller becomes aware of any such delay.
4. SHIPMENT, TTITLE AAND RRISK OOF LLOSS - Unless the delivery terms of this contract expressly
provide for F.O.B. destination, shipping/delivery will be F.O.B. Seller's point of shipment with title to
the goods and risk of loss or damage passing to Buyer at that point. Buyer will be responsible for
shipment during transit and for filing any damage or loss claims directly with the carrier. Seller
may make partial shipments.
5. TAXES - Any applicable duties or sales, use, excise, value-added or similar taxes will be
added to the price and invoiced separately (unless an acceptable exemption certificate is fur-
nished).
6. TERMS OOF PPAYMENT - (a) Unless otherwise stated, all payments shall be in United States
dollars, and a pro rata payment shall become due as each shipment is made. If shipment is
delayed by Buyer, date of notice of readiness for shipment shall be deemed to be date of ship-
ment for payment purposes.
(b) On late payments, the contract price shall, without prejudice to Seller's right to immediate pay-
ment, be increased by 1 1/2% per month on the unpaid balance, but not to exceed the maximum
permitted by law.
(c) If any time in Seller's judgment Buyer is unable or unwilling to meet the terms specified, Seller
may require satisfactory assurance or full or partial payment as a condition to commencing or
continuing manufacture or making shipment, and may, if shipment has been made, recover the
goods from the carrier, pending receipt of such assurances.
7. NONCANCELLATION - Buyer may not cancel or terminate for convenience, or direct suspen-
sion of manufacture, except with Seller's written consent and then only upon terms that will com-
pensate Seller for its engineering, fabrication and purchasing charges and any other costs relating
to such cancellation, termination or suspension, plus a reasonable amount for profit.
8. NUCLEAR - Buyer represents and warrants that the goods covered by this contract shall not
be used in or in connection with a nuclear facility or application. If Buyer is unable to make such
representation and warranty, then Buyer agrees to indemnify and hold harmless Seller and to
waive and require its insurers to waive all right of recovery against Seller for any damage, loss,
destruction, injury or death resulting from a "nuclear incident", as that term is defined in the
Atomic Energy Act of 1954, as amended, whether or not due to Seller's negligence.
9. LIMITATION OOF LLIABILITY - Neither Seller, nor its suppliers shall be liable, whether in con-
tract, warranty, failure of a remedy to achieve its intended or essential purposes, tort (including
negligence), strict liability, indemnity or any other legal theory, for loss of use, revenue or profit, or
for costs of capital or of substitute use or performance, or for indirect, special, liquidated, inciden-
tal or consequential damages, or for any other loss or cost of a similar type, or for claims by Buyer
for damages of Buyer's customers. Seller's maximum liability under this contract shall be the con-
tract price. Buyer and Seller agree that the exclusions and limitations set forth in this article are
separate and independent from any remedies which Buyer may have hereunder and shall be
given full force and effect whether or not any or all such remedies shall be deemed to have failed
of their essential purpose.
10. GOVERNING LLAW AAND AASSIGNMENT - The laws of the State of Georgia shall govern the
validity, interpretation and enforcement of this contract, without regard to its conflicts of law prin-
ciples. The application of the United Nations Convention on Contracts for the International Sale of
Goods shall be excluded. Assignment may be made only with written consent of both parties;
provided, however, Seller may assign to its affiliate without Buyer's consent.
11. ATTORNEY FFEES - Buyer shall be liable to Seller for any attorney fees and costs incurred by
Seller in enforcing any of its rights hereunder.
12. DISPUTES - Either party may give the other party written notice of any dispute arising out of
or relating to this contract and not resolved in the normal course of business. The parties shall
attempt in good faith to resolve such dispute promptly by negotiations between executives who
have authority to settle the dispute. If the matter has not been resolved within 60 days of the
notice, either party may initiate non-binding mediation of the dispute.
13. STATUTE OOF LLIMITATIONS - To the extent permitted by applicable law, any lawsuit for
breach of contract, including breach of warranty, arising out of the transactions covered by this
contract, must be commenced not later than twelve (12) months from the date the cause of
action accrued.
14. PRICES - In the event of a price increase or decrease, the price of goods on order will be
adjusted to reflect such increase or decrease. This does not apply to a shipment held by request
of Buyer. Goods already shipped are not subject to price increase or decrease. Orders on a bid or
contract basis are not subject to this article. Seller's prices include the costs of standard domes-
tic packing only. Any deviation from this standard packing (domestic or export), including U.S.
Government sealed packing, will result in extra charges. To determine such extra charges, consult
Seller's sales offices. Orders of less than $400 will be charged a $25 handling fee.
15. ADDITIONAL TTERMS OOF PPAYMENT - (a) Invoice payment terms are as shown on latest dis-
count sheets as issued from time to time. Cash discounts are not applicable to notes or trade
acceptances, to prepaid transportation charges when added to Seller's invoices or to discount-
able items if there are undisputed past due items on the account. Portions of an invoice in dis-
pute should be deducted and the balance remitted with a detailed explanation of the deduction.
Cash discounts will only be allowed on that portion of the invoice paid within the normal discount
period.
(b) Freight will be allowed to any common-carrier free-delivery point within the United States,
excluding Alaska and Hawaii, on shipments exceeding $1,000 net or more providing Seller selects
the carrier. On shipments to Alaska and Hawaii, freight will be allowed to dockside at the listed
port of debarkation nearest the destination point on shipments of $1,000 net or more. Buyer shall
pay all special costs such as cartage, stevedoring and insurance. Special freight allowances are
as shown on latest discount sheets as issued from time to time. Cataloged weights are estimat-
ed, not guaranteed. Seller assumes no responsibility for tariff classifications on carriers.
16. CHANGES IIN LLAWS AAND RREGULATIONS - Seller's prices and timely performance are based
on all applicable laws, rules, regulations, orders, codes, standards or requirements of governmen-
tal authorities effective on the date of Seller's proposal. Any change to any law, rule, regulation,
order, code, standard or requirement which requires any change hereunder shall entitle Seller to
an equitable adjustment in the prices and any time of performance.
