Binary Command Interface
IFC-1 and IFC-3
Slots IFC-1 and IFC-3 must be equipped with an interface module IFC-D (high
contact load) or IFC-P (normal contact load). The commands to be transmitted by
the protective relay are also connected here (binary inputs). Output of the
received commands to the protective relay is also via these modules.
IFC-2 and IFC-4
Additional slots for IFC-2 and IFC-4 are available. These additional slots can be
equipped with one of the following IFC types:
•
IFC-D
•
IFC-P
•
IFC-S (signaling)
If these slots are equipped with an IFC-D or IFC-P, the relays of these modules can
be used (in case of analog transmission) for doubling the command output
contacts. In case of contact doubling the inputs are not used.
If these slots are equipped with an IFC-S module, these modules are used for one
of the following cases:
•
For signaling commands that are entered (activation of binary inputs)
•
For signaling commands that are output (binary output)

NOTE
Use flyback diodes for any relays that are connected to an output SWT to avoid EMC influences.
