Description

SIRIUS safety relay output extension 4RO with relay enabling circuits 4 NO contacts plus relay signaling circuit 1 NC contact US = 24 V DC spring-loaded connection (push-in) output extension SIRIUS 3SK1 for safety relays.
The output extensions 3SK are used to supplement a basic unit with additional safe outputs with a switching capacity of up to 10 A. They can be connected to any 3SK basic unit by wiring. All devices with a control supply voltage of 24 V DC can also be connected to the basic units Advanced 3SK1 and 3SK2 by means of device connector 3ZY12.
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. Available through-the-wall with screw or spring-type terminals (push-in).
The 3SK safety switching devices replace the proven 3TK28 series.
Safety is a SIRIUS business.
