Input current, enable circuit:
Terminals 48, 63, 64 and 65: Input current, optocoupler approx. 12 mA at +24V
Terminals 663: Input current, optocoupler and start inhibit relay approx. 30 mA
at +24 V
When selecting the switching devices, auxiliary contacts at the main switch, the
contact reliability when switching low currents should be taken into account.
Switching capability of the signal contacts:
The max. switching capability of the signal contacts is specified in the interface
overviews of the modules in Section 5 and 6 and must be carefully observed!
Note
All connected actuators, contactor coils, solenoid valves, holding brakes etc.
must be provided with overvoltage limiters, diodes, varistors etc.
This is also true for switching devices/inductances which can be controlled from
a PLC output.
