Siemens 3RS1142-1GW80 Wide-Range Temp Relay | 24-240V AC/DC | Phased-Out
Siemens 3RS1142-1GW80 multi-temp relay, 24-240V AC/DC, -99 to 1800°C.
The Siemens 3RS1142-1GW80 is a high-performance temperature monitoring relay supporting multiple thermocouple types (J, K, T, E, N, S, R, B) and featuring digitally adjustable setpoints for temperatures ranging from -99°C to 1800°C, depending on the sensor. A key feature is its wide operating voltage range of 24-240V AC/DC, offering flexibility in power supply options. This 45 mm wide relay provides two sets of outputs, each with 1 change-over (CO) and 1 normally open (NO) contact, connected via screw terminals. This unit is phased-out, with the preferred successor being the 3RS2600-1BW30.
This relay is designed for critical temperature monitoring in diverse industrial settings, including demanding environments with fluctuating voltage supplies. Its broad thermocouple compatibility and wide temperature range make it suitable for applications in metallurgy, plastics processing, chemical plants, and advanced manufacturing.
