C.A 3420 Threshold Relay
Control your temperature control loops in total safety
According to good thermal safety practices, a temperature loop must be controlled by a second thermal safety loop. This second safety loop must be totally independent from the main control loop, so it must have its own temperature sensor.
The use of a threshold relay provides essential safety and protection in order to:
- detect any dysfunction of the heating elements,
- anticipate and react quickly if an anomaly is detected,
- avoid any interruptions on the production line.
