ABB pluggable interface relays and optocouplers of the CR-S Range are used for electrical isolation, amplification and signal matching between the electronic controlling, e.g. PLC, iPC or field bus systems and the sensor / actuator level. The CR-S Range combines the flexibility of a modular system and the ability of switching high currents on a small footprint thus can be used in applications where space saving is essential. Main benefits include Space saving; Modular & LED integrated on all sockets. Main features include 9 different coil voltages from 5-24 V DC / 12-230 V AC/DC; 1 c/o contact (6 A), Transistor, MOS-FET, Triac; Optional gold plated version available; LED integrated in all sockets; Complete variants for high runners such as 24 V AC/DC, 110 V AC/DC, 230 V AC/DC & Accessories like jumper bars, markers and separators avialable.
