Signal contact
The signal contact is a potential-free N/O contact of a semiconductor relay. Through terminals 3 and 4
of the NECA-... multi-pin plug socket, the contact can be picked up in the feedback circuit of a safety
control system.
Note
Operation of the signal contact outside the permitted technical data results in its irre-
parable failure. Compliance with the specification must be ensured through an appro-
priate protective circuit.
Note
Assignment of these contacts is not required to achieve the safety category.
