Reliable Temperature Monitoring with Adjustable Thresholds
The ABB CM-TCS.23P monitors temperature through a connected Pt100 resistance temperature sensor. The resistance of the sensor changes with temperature, allowing the relay to evaluate the monitored condition and compare it against the configured switching thresholds.
With a measuring range of 0 to +200 °C, the CM-TCS.23P is suitable for supervising industrial equipment and processes that require temperature-based switching signals. Its two adjustable thresholds allow the monitoring response to be adapted to the installation.
The relay provides overtemperature monitoring to detect excessive temperatures, undertemperature monitoring to identify temperatures below a selected limit and window monitoring to supervise whether the measured temperature remains within a defined range.
These monitoring functions can be integrated into industrial control systems to activate alarms, signal PLC inputs or operate appropriately rated external control devices.
Overtemperature, Undertemperature and Window Monitoring
The CM-TCS.23P offers two adjustable temperature thresholds, allowing different operating conditions to be monitored with one compact relay.
In overtemperature monitoring, the relay can indicate when the measured temperature rises beyond the configured threshold. This is useful for identifying overheating in equipment, machinery and industrial processes.
In undertemperature monitoring, the relay can detect when the measured temperature falls below the selected limit. This can be useful in applications where a minimum operating temperature must be maintained.
With window monitoring, two thresholds define an acceptable temperature range. The relay can provide a switching response when the measured temperature moves outside the configured operating window, supporting both high-temperature and low-temperature supervision.
The output contacts can be configured for suitable common or separate switching arrangements, allowing the temperature monitoring signals to be integrated into the control system according to the required operating function.
Easy Connect Installation and Industrial Control Integration
The ABB CM-TCS.23P uses Easy Connect push-in terminals, providing screwless spring-clamp electrical connections that simplify installation and reduce routine maintenance requirements.
Its two changeover contacts, rated at 250 V / 4 A, support integration with compatible alarm circuits, PLC inputs, contactor controls and other industrial switching arrangements.
The relay also incorporates sensor short-circuit detection, helping identify a fault in the connected measuring circuit. Correct sensor selection, wiring and installation remain important for dependable temperature measurement.
The compact 22.5 mm DIN rail housing makes the device suitable for industrial control cabinets and machinery panels. Front-mounted adjustment controls support convenient commissioning, while an optional sealable transparent cover can help protect the configured settings against unauthorised changes.
