Safety Relay 3SK1121-1AB40 Eletronic pieces The voltage category of theSIRIUS 3SK1 Advanced Safety Relay Configurable The safety relays of the Advanced series comprise basic devices and input and output expansions. The Advanced devices can be connected by means of a 3ZY12 device connector. When configuring the system, it must be ensured that input expansions are always mounted on the left, and output expansions (3SK121) on the right of the basic unit. For control supply voltages of 110 240 Vac dc, the Advanced series can
