CR-S interface relays

Space-saving interface relays and optocouplers

The ABB CR-S range of pluggable interface relays and optocouplers is used for electrical isolation, amplification and signal matching between electronic controls – PLCs, iPCs or field bus systems – and the sensor / actuator level. The CR-S range combines the flexibility of a modular system with the ability to switch high currents. Its small footprint makes it ideal for applications where space savings are essential.
