Max. cross-section that can be connected 1.5 mm
The 2-pole terminal connector for the signaling contact is included in the Completion Kit provided.
The signaling contact can be connected with a digital input (DI) on the Control Unit or other
digital interface (PLC, SCADA). In parallel or redundant operation the failure of a Control
Supply Module is indicated in order to initiate a service call, for example.
The signaling contact operates as an isolated NO contact. When the switch is closed, the
Control Supply Module is "OK" and provides the output voltage. The switch opens in the
event of a fault "Not OK" – when the overtemperature condition is still present, after a pre-
warning, wire breakage, short-circuit etc. The Control Supply Module is correspondingly
switched off.
