ABB Boxed interface relays of the R600 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 relay itself is built in thus the perfect solution because this design fulfills highest vibration requirements. The compact design and different connection terminal possibilities further optimize your panel installation. Main benefits include Space saving; Highly vibration resistant & High switching currents on a small footprint. Main features include Screw- or spring-type terminals; 8 different coil voltages from 5-24 V DC / 24-230 V AC/DC; 1 n/c contact, 1 n/o contact, 1 c/o contact or 2 c/o contacts available; Optional built in RC element avilable & Up to 4 mm² wire can be connected.
