It delivers a 24 V DC output rated up to 40 A from a 24 V DC input, with an integrated battery to bridge outages and maintain control circuits. Status is indicated by three LEDs: green OK for normal operation, yellow Bat signaling battery\/hold-up mode, and red Alarm for faults. The unit provides floating changeover contacts for remote monitoring or interlocks—useful for signaling “24 V DC OK\/Bat” and “Alarm” to other equipment. This variant is specified without a serial interface, distinguishing it from versions that include USB or RS-232 connectivity. Typical applications include safeguarding PLCs, drives, sensors and other 24 V DC devices in SITOP-powered systems such as SIMATIC ET200 Distributed I\/O environments, where continuous 24 V power is essential and a compact UPS solution is needed. Input terminals are designated L+ and M, while the output remains 24 V DC to the load, supporting up to 40 A of current. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268484452586,"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-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6ep1931-2fc01-profibus-interface-module","provider":"GTG Hardware","version":"1.0","type":"link"}
