The IM 460-1 interface module can be inserted into the following central controllers:

• UR1,
• UR2 and
• CR2.

No more than 2 expansion units can be connected (1 per interface). No more than 2 IM 460-1 units can be plugged in per central controller.

The IM 460-1 supplies the modules in the connected expansion units with the 5 V supply voltage (max. 5 A per interface). In this case, there must be no power supply module in the downstream expansion units.

The module has:

• 3 LEDs for indicating faults.
• 2 interfaces for connecting the expansion lines via 468-3 connecting cable.
