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.
