SIRIUS Safety Relay Output Expansion Unit 4RO with Relay Enable Circuits – 3SK12111BB40 is backordered and will ship as soon as it is back in stock.
SIRIUS safety relay output expansion 4RO with relay enable circuits, 4 NO contacts plus relay signaling circuit, 1 NC contact, Us = 24 V DC screw terminal, SIRIUS 3SK1 output expansion for safety relays. The 3SK output expansions are used to add additional safe outputs to a basic unit 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 3SK1 and 3SK2 Advanced basic units using 3ZY12 device connectors. The devices have four (AC-15 5 A) or three (AC-15 10 A) safe outputs. A choice between 24 V control voltage or wide-range voltage is available. Available throughout with screw terminals or spring-type (push-in) terminals. The 3SK safety relays replace the proven 3TK28 series. Safety is a SIRIUS business.
