Siemens 3RS2041-1GW50

The Siemens 3RS2041-1GW50 is a temperature monitoring relay designed for use with PT100, PT1000, and KTY83/84 sensors, as well as NTC sensors. It supports monitoring up to three sensors simultaneously and offers two digitally adjustable threshold settings, covering a wide temperature range from -58 °F to 932 °F. Operating on a voltage range of 24 to 240 V AC/DC, this relay features two changeover contacts and one normally open contact, all housed within a compact 45 mm width enclosure with screw terminals for straightforward installation. While this particular model has been phased out, it remains available through BSP Automation, providing a reliable option for your temperature control needs until a successor model is adopted.
