•
Has an insulated housing and is intended for DIN rail mounting. The snap-on fastener fits a 35 mm
DIN rail, as per DIN EN 50022.
•
The auxiliary voltage is connected via 2 terminals. The large auxiliary voltage ranges of DC 24 V to 250 V
and AC 60 V to 230 V allow connection to all common station batteries or alternating voltage networks.
•
The RS232 interface is connected using the 9-pin X1 D-sub socket. The fiber-optic channels are
connected using ST connectors.
•
Using the isolated signaling contact X7, terminal 1/2, a failure indication can be transmitted to a network
