Why Choose the ABB CM-TCS.21P Temperature Monitoring Relay?
The ABB CM-TCS.21P is a compact temperature monitoring relay designed for reliable temperature supervision in industrial machinery, processes and control systems. Supplied under ABB order code 1SVR740740R9100, it provides a temperature measuring range of -50 to +50 °C and operates from a 24 V AC/DC control supply.
The CM-TCS.21P monitors temperature through one PT100 sensor circuit and provides overtemperature, undertemperature and window monitoring. Two adjustable threshold values allow upper and lower temperature limits to be set according to the application, making the relay suitable for heating, cooling and general process-temperature supervision.
Two changeover (SPDT) output contacts, each rated at 250 V / 4 A, provide flexible signalling and control. Maintenance-free Easy Connect push-in terminals and a slim 22.5 mm DIN rail housing simplify installation in industrial control panels.

Reliable PT100 Temperature Monitoring for Industrial Systems
The ABB CM-TCS.21P evaluates the signal from a connected PT100 resistance temperature sensor and compares the measured temperature with two adjustable thresholds. Depending on the selected monitoring function, the relay can detect an overtemperature condition, an undertemperature condition or temperatures outside a defined operating window.
When a configured temperature limit is reached, the two changeover outputs can be used to operate alarms, contactors or other control equipment. Its -50 to +50 °C measuring range makes the CM-TCS.21P particularly suitable for applications requiring supervision around ambient, cooling or low process temperatures.
Typical Applications
- Industrial machinery temperature monitoring.
- Heating and cooling control systems.
- HVAC and ventilation equipment.
- Process equipment and production machinery.
- Control cabinet temperature supervision.
- Cold-room and refrigeration control systems.
- Temperature monitoring of solid, liquid and gaseous media.
- Applications requiring upper and lower temperature threshold supervision.
