Siemens 3RS1041-2GW50

The Siemens 3RS1041-2GW50 is a temperature monitoring relay designed to work with various sensors, including PT100, PT1000, KTY83/84, and NTC types. It supports up to three sensors and offers two digitally adjustable threshold values within a wide temperature range of -50 °C to 500 °C. Operating on a voltage supply from 24 to 240 V AC/DC, it features two changeover (CO) contacts and one normally open (NO) contact, all accessible through spring-loaded terminals. The device is compact, with a width of just 45 mm, making it suitable for integration in control panels where space is limited. Although this particular model has been phased out, BSP Automation continues to provide support and can assist with its preferred replacement, the Siemens 3RS2600-2BW3.
