Up to nine PTC sensors according to DIN 44081, DIN 44082 can be connected to the measurement circuit input of the INT69, each with different rated trigger temperatures. It is therefore possible to monitor several measurement points with just one INT69 trigger device.
If the temperature in one of the monitored parts or sections reaches the specified trigger temperature of the PTC sensor, the resistance increases and the trigger device switches off.
The device automatically reactivates once the temperature has dropped back down.
The relay switch output is designed as an isolated switch contact. This circuit works on the closed current principle, i.e. the relay goes into its neutral position when there is a sensor or cable break and switches off.
Galvanic separation between sensor, relay and power supply circuits.
