(1) Protective circuit
The protective circuit provides the required security against destruction and interference.
(2) Setting of the input rated voltage
You can set the input rated voltage to the values DC 24 V, DC 48/60 V, DC 110 V, and DC 250 V
with the jumpers X43 to X58. The operating point is at 80 % of the selected voltage.
Refer to
(3) Rectifier
Rectification ensures that the input signal is polarity-neutral.
(4) Optocoupler
The optocoupler isolates the input circuit electrically from the electronic system.

Signal Output from the IFC-D/P Module

8.1.9
If there is an IFC-D module, the commands from the remote station are distributed via the relays K1 to K4. If
there is an IFC-P module, the commands from the remote station are distributed via the relays K13 to K16.
Compared with the IFC-P module, the relays of the IFC-D module are slower but they can switch more power.
