The second interface module is used in the case of an IFC-D/P module for doubling the output contacts. The
binary inputs are only connected to one module (in slot IFC-1 or IFC-3).
If the IFC-S module is used, jumpers X43 to X58 are not provided because the binary inputs do not exist.
The module contains 8 signaling relays. For 7 relays, one change-over contact is brought out in each case. The
contact of relay K5 can be used as a make contact or a break contact with jumper X42. All 8 signaling contacts
have a common root (3A1).
DIP Switches on IFC Modules
There are 2 Dual Inline Package (DIP) switches added to each IFC modules:
•
DIP switch S1 for the Test Mode.
The activated output relays are displayed with LEDs H1 to H4 (red), and the activated binary inputs with
LEDs H5 to H8 (green).
For more detailed information, refer to Interface Command Module
•
DIP switch S2 for the selection of PU3 and PU4 module and to indicate the slot address of each IFC
module.
For more detailed information, refer to
8.1.7 Slot and Module Identifier

CAUTION
Changing the position of an IFC module without changing its address may lead to a failure in the transmis-
sion.
The IFC module will be detected on a wrong slot. No information or wrong information may be trans-
mitted to the corresponding protection relay.
²
Make sure that the IFC module is in the right slot.
