Description

SIRIUS safety relay Input expansion Advanced Input expansion for an additional 2-channel or two 1-channel sensors Us = 24 V DC screw terminal Sensor extension SIRIUS 3SK1 for safety-oriented expansion of the Advanced basic units. The 3SK1220 sensor expansion allows additional sensors to be integrated easily and flexibly into the 3SK system without the need for additional wiring outlay between the devices. The device monitors two single-channel sensors or one 2-channel sensor, regardless of their output technology (floating or non-floating). All the devices are available with screw-type or spring-type terminals (push-in). The 3SK safety relays are replacing the proven 3TK28 series. Safety is a SIRIUS business.
