It provides 2 or 4 fail-safe digital inputs (F-DI) and 2 fail-safe digital outputs (F-DO), and is parameterizable via MSS ES for flexible safety circuit configuration. The module is 22.5 mm wide with screw-terminal connections, designed to extend safety-related input and output capacity in a 3RK3 installation. It supports up to SIL 3 (IEC 61508) and up to Performance Level e (ISO 13849-1) in appropriate system configurations, making it suitable for safety tasks such as interfacing safety sensors and actuators, interlocks, and safety-related signaling within a SIRIUS MSS setup. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268099887338,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3rk3231-1aa10-programmable-logic-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
