SIRIUS safety relay Output expansion 4RO with relay enabling circuits 4 NO contacts plus Relay signaling circuit 1 NC contact Us = 24 V DC screw terminal Output expansion SIRIUS 3SK1 for safety relays.The 3SK output expansions are used for supplementing basic units with additional safe outputs with a switching capacity of up to 10 A. They can be connected to each 3SK basic unit by wiring. All devices with a 24 V DC control supply voltage can also be connected to the 3SK1 and 3SK2 Advanced basic units using 3ZY12 device connectors.The devices have four (AC-15 5 A) or three (AC-15 10 A) fail-safe outputs. There is a choice between a control supply voltage of 24 V or a wide voltage range. Available with screw or spring-type terminals (push-in) across the board.The 3SK safety relays are replacing the proven 3TK28 series.Safety is a SIRIUS business.

Are you still working in Excel? Seriously...
Constantly changing demands, but also changing technology and export guidelines are well-known challenges for a machine- and panel builder. An ever-increasing response time is the enduring trend and process optimization a requirement. Therefore, the time is really over to manually keep track of things around an electro-technical design in an excel sheet. The time and stress that this takes and the chance of errors that such a method entails, no longer fits in a world that is changing ever faster and is becoming more digital. After all, what machine or panel builder doesn't want to be able to select the right switching and protection devices for a motor or load at the push of a button, including required cable diameters and short-circuit calculations?
