Input/output (I/O) modules

5

Internal current consumption:

(from V+ bus)

0 mA

External current consumption: 0 mA

Terminals: Pluggable 10-pole screw terminal block

(4 405 4847 0), for wires up to 1.5 mm²

As the current consumption of this module is considerable, when using a number

of them in the same system, the total load for all modules must be taken into

consideration..
