bus. The bus starts on the basic unit and goes over all the modules. The order of
modules on the bus is irrelevant. And it also irrelevant which bus connector on the
module is used as the input and which is used as the output.
The modules include a 220 mm long bus interconnecting cable; Wie Part No. 9155037
gand modules and I/O modules include an 80 mm long bus cable. Part No. 9155034
You can order a separate 1 m long bus cable ( , , Part Nos. 9155050 9155054
) of the length of 1 m, 3 m or 5 m for remote module installation. Typically, it 9155055
helps install an RFID card reader on the opposite side of the wall on which the 2N

Access Unit
powered from the bus. The available bus power output depends on the power supply
type. The basic unit can use a 2A power supply to increase the bus power available to
the modules connected.
Power supply Specification Available power output
External supply 12 V ±15% / 2 A (3 A) 24 W (36 W)
PoE 802.3af (Class 0 – 12.95 W) 12 W
Combined External PoE 30 W (42 W)
The count of modules on the bus is limited by the available power supply output. The
maximum count of the modules on the bus is 30.
