Type EXR20


~ 52 mm
Typ EXR20 von E-T-A: EXR20 (Electronic eXtra Relay) wurde speziell für die Ansteuerung von Elektromotoren entwickelt.

The EXR20 (Electronic eXtra Relay) has specially been designed for the control of electric motors. It combines a microcontroller with mechanical contacts and additional overcurrent protection.

  • High flexibility for your application through clockwise and counterclockwise rotation of the electric motor.
  • Convenient and reliable control of electric motors with only two signal outputs.
  • Enhanced safety for your application through an adjustable overcurrent protection.

The EXR20 special relay is available for DC 12 V and DC 24 V applications and is suitable for standard automotive relay sockets to ISO 7588.
