Function
J 50 mA
The KFD2-CD-Ex1.32 transmits an
electrical unit signal from the safe area
to the hazardous area. The conversion
of a current signal into a voltage signal
10- 9+ 11+ 10- 9+ 11+
and vice versa is possible.
10- 9+ 11+ 10- 9+ 11+ 7+ 8-
Current input option
Power supply Power Rail
A current limit circuit in series to
terminal 9 protects the device from
Input Input
damage. The max. voltage drop at the
Current source Voltage
input is DC 4 V, allowing for the
connection of several KFD2-CD32-
Ex1.32 repeaters due to the low voltage
Composition
drop in order to maintain multiple
galvanically isolated outputs (signal
duplication).
Voltage input option
The signal is transmitted to terminals 9
and 10 across an amplifier and the
DC/DC converter within the allowable
voltage range. A voltage limiter circuit
protects the amplifier from incorrect
input switching and overvoltage, but will
draw current through a 50 mA fuse
during operation. The fuse can be
changed only by the manufacturer.
Current output option
The open circuit voltage is DC 24 V
within the allowable supply voltage
range at terminals 1 and 2. The max.
load that can be applied is 850 ?.
Voltage output option
At least 20 mA is available within the
allowable supply voltage range at
terminals 1 and 2 which means that with
10 V output voltage, a load of at least
500 ? must be connected.

Accessories
Power Rail PR-03
Power Rail UPR-03
Power feed module KFD2-EB2...
Using Power Rail PR-03 or UPR-03 the devices are supplied with 24 V DC by means of the power feed modules. If no Power
Rails are used, power supply of the individual devices is possible directly via their device terminals.
Each power feed module is used for fusing and monitoring groups with up to 100 individual devices. The Power Rail PR-03 is
an inset component for the DIN rail. The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium
profile rail 35 mm x 15 mm x 2000 mm. To make electrical contact, the devices are simply engaged.
The Power Rail must not be fed via the device terminals of the individual devices!
