This signal conditioner provides the isolation for nonintrinsically safe applications.
The device is a universal frequency converter that changes a
digital input signal into a proportional free adjustable
0/4 mA ... 20 mA analog output signal and functions as a
switch amplifier and a trip alarm.

The functions of the switch outputs (2 relay outputs and
1 potential free transistor output) are easily adjustable [trip
value display (min/max alarm), serially switched output, pulse
divider output, error signal output].
The device is easily configured by the use of keypad or with
the PACTware configuration software.
A fault is signalized by LEDs acc. to NAMUR NE44 and a
separate collective error message output.

Accessories
Power feed module KFD2-EB2
The power feed module is used to supply the devices with 24 V DC via the Power Rail. The fuse-protected power feed module
can supply up to 150 individual devices depending on the power consumption of the devices. A galvanically isolated mechanical
contact uses the Power Rail to transmit collective error messages.
Power Rail UPR-03

Release date 2012-11-28 13:28

188369_eng.xml

The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium profile rail 35 mm x 15 mm. To make
electrical contact, the devices are simply engaged.
Profile Rail K-DUCT with Power Rail
The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables.
Due to this assembly no additional cable guides are necessary.
Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!

PACTware™
Device-specific drivers (DTM)
Adapter K-ADP1
Programming adapter for parameterisation via the serial RS 232 interface of a PC/Notebook
For programming, please use the new version of adapter K-ADP1 (part no. 181953, connector length 14mm). When using the
previous version K-ADP1 (connector length 18 mm) the plug is exposed by approx. 3 mm. The function is not affected.
Adapter K-ADP-USB
Programming adapter for parameterisation via the serial USB interface of a PC/Notebook
Subject to reasonable modifications due to technical advances.
