Assembly
• 1-channel signal conditioner
• 24 V DC supply (Power Rail)
• Input for 2- or 3-wire sensors, NAMUR sensors or dry
contacts
• Input frequency 1 mHz ... 12 kHz
• Current output 0/4 mA ... 20 mA
• Relay and transistor output
• Start-up override
• Line fault detection (LFD)
• Up to SIL2 acc. to IEC 61508
Function
This signal conditioner provides the isolation for non-
intrinsically 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.
For additional information, refer to the manual and

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
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!
