Siemens 3RS2140-1GD60

The Siemens 3RS2140-1GD60 is a temperature monitoring relay designed for use with various thermocouples, including types J, T, E, and K. This device allows for precise digital adjustment of two threshold values, covering a broad temperature range from -99 °F up to 1830 °F. Operating on 24 V AC/DC power, it features two contact outputs—one normally closed and one normally open—housed in a compact 45 mm width unit with screw terminals for straightforward installation. While this particular model has been phased out, it remains a reliable choice for applications requiring accurate temperature control. BSP Automation distributes this relay, offering support for your automation needs and helping guide you to suitable alternatives if needed.
