R600 Boxed Interface Relays & Optocouplers

Boxed interface relays and optocouplers

The ABB R600 boxed interface relay range is used for electrical isolation, amplification and signal matching between the electronic controls –  PLCs, iPCs or field bus systems – and the sensor / actuator level. The built-in relay ensures the design fulfills the highest vibration requirements. The compact design and different connection terminal options help produce optimized panel installations.
