Further details:
SIRIUS Safety Switch Device Input Expansion Advanced. Input expansion for one additional 2-channel or two 1-channel sensors Us = 24 V DC. Spring terminal connection (Push-In). Sensor expansion SIRIUS 3SK1 for safety-oriented expansion of the basic devices Advanced. The sensor expansion 3SK1220 allows for easy and flexible integration of additional sensors into the 3SK system without additional wiring effort between devices. The device monitors two 1-channel or one 2-channel sensor regardless of its output type (potential-free or potential-bearing). The devices are available with screw or spring terminal connection (Push-In). The safety switch devices 3SK replace the proven series 3TK28. Safety is a SIRIUS business.
