Power requirement of supplementary components
The following components are connected in each case in the installed S120 Cabinet Modules downstream of the fuse
protection for the auxiliary voltage supply system. The power requirement must be added to the basic requirement of
the relevant Cabinet Module specified on the pages above.
CU320-2 Control Unit
Voltage 24 V DC (20.4 V – 28.8 V)
Maximum power requirement (at 24 V DC) without taking
account of digital outputs and expansions in the option slot
1.0 A
Maximum fuse protection 20 A
Digital inputs: 12 floating digital inputs
8 bidirectional non-floating digital outputs/digital inputs
§ Voltage -3 V to +30 V
§ Low level (an open digital input is interpreted as "low") -3 V to +5 V
§ High level +15 V to +30 V
§ Power consumption (typ. at 24 V DC) 9 mA
Digital outputs (continuously short circuit proof): 8 bidirectional non-floating digital outputs/digital inputs
