Siemens 3SK1211-2BW20 safety relay

SIRIUS safety relay output extension 4RO with relay enabling circuits 4 make contacts plus relay signaling circuit 1 break contact Us = 110-240 V AC/DC spring-loaded connection (push-in) output extension SIRIUS 3SK1 for safety relays. The 3SK output extensions are used to supplement a basic device with additional safe outputs with a switching capacity of up to 10 A. They can be connected to any 3SK basic device by wiring. All devices with a control supply voltage of 24 V DC can also be connected to the Advanced 3SK1 and 3SK2 basic devices using the 3ZY12 device connector. The devices have four (AC-15 5 A) or three (AC-15 10 A) safe outputs. You can choose between a control voltage of 24 V or a wide voltage range. Available with screw or spring-loaded connection (push-in). The 3SK safety relays replace the tried-and-tested 3TK28 series. Safety is a SIRIUS business.
