Error OUT TTL output
Levels:

passive 5 V

active 0 V
Error IN TTL input

Low active
Secure switching threshold at least 10 mA
After receiving a signal (short-circuit to ground) from
an external device, an error message appears and the
device stops.
Error GND Reference point of the voltage at the signal inputs.
+24V Event-controlled switching of 24 V
against GND
Protection: 24 V – 200 mA
+5V Provides a voltage of 5 V with respect to GND. This
makes it possible to supply a consumer that is
switched by an EVENT.
Protection: 5 V – 50 mA
GND Reference point of the voltage at the signal inputs.
