It supports overtemperature monitoring, undertemperature monitoring and combined overtemperature/undertemperature monitoring, allowing users to detect temperatures outside a defined operating range.
The relay operates from a wide 24–240 V AC/DC control supply, making it suitable for a variety of industrial control voltage arrangements. Its two change-over relay contacts can be configured for individual or combined operation, providing switching signals for compatible alarms, contactors, programmable logic controllers and other automation equipment.
With its compact 22.5 mm DIN rail-mounted housing, double-chamber cage screw terminals, front-mounted adjustment controls and LED status indication, the ABB CM-TCS.13S offers a practical solution for temperature monitoring in industrial electrical panels. An optional sealable transparent cover is available to help prevent unauthorised adjustment of the settings.

Reliable Temperature Monitoring for Industrial Heating and Process Control
Accurate temperature supervision is essential in industrial systems where excessive heat or insufficient operating temperature can affect machinery, production quality and equipment reliability. The ABB CM-TCS.13S temperature monitoring relay provides dependable temperature monitoring across its 0 to +200 °C measuring range, making it suitable for applications requiring supervision at higher temperatures than the 0 to +100 °C variants in the CM-TCS family.
The relay uses a connected PT100 resistance temperature sensor to measure temperature. As the temperature changes, the electrical resistance of the sensor changes in a predictable manner. The CM-TCS.13S evaluates this resistance and compares the resulting temperature measurement against the configured thresholds.
For overtemperature monitoring, the relay can provide a switching signal when the measured temperature exceeds a selected upper limit. This is useful for supervising industrial heaters, machinery and process equipment where excessive temperature could cause damage or interrupt production.
For undertemperature monitoring, the relay can identify when the measured temperature falls below a configured lower threshold. This function is useful in processes that must reach or maintain a minimum operating temperature before machinery or production equipment can operate correctly.
The combined overtemperature and undertemperature function allows the relay to supervise a defined temperature window. With two adjustable thresholds, the CM-TCS.13S can signal when the monitored temperature moves outside the acceptable range, supporting process stability and automated alarm handling.
The relay also provides adjustable hysteresis, helping prevent repeated switching when the measured temperature fluctuates close to a threshold. This can be especially useful in heating and cooling applications where minor temperature variations are normal during operation.
Its two change-over relay contacts can be configured for individual or combined operation. This allows the CM-TCS.13S to provide switching signals to compatible alarms, contactor circuits, programmable logic controllers and industrial automation systems. The relay is intended for monitoring and signalling; higher-power heating or cooling loads should be switched through appropriately rated external equipment.
The 24–240 V AC/DC control supply offers flexibility when integrating the relay into different industrial control systems. Its compact DIN rail-mounted housing, screw-terminal connections and front-mounted controls simplify installation and commissioning in machine control cabinets and process automation panels.
For maintenance and reliability, the CM-TCS.13S includes sensor short-circuit detection, which helps identify certain faults in the measuring circuit. LED status indication provides visual feedback, while the optional sealable transparent cover helps protect settings against unintended adjustment.
