Product Details

CM-TCS Temperature Monitoring Relays

The temperature monitoring relays CM-TCS monitor over-temperature, under-temperature, or temperatures between two threshold values with PT100 sensor. When the temperature falls below, or exceeds the maximum value, the output relays instantaneously change their positions according to the configured functionality. The front-face LED will display the current status.

Available with two different terminal versions (screw connection or Easy Connect push-in)
All configurations and adjustments by front-face operating elements
Precise adjustment with direct reading scales
Short circuit monitoring and interrupted wire detection
3 LEDs for the indication of operational states


Housing material for highest fire protection classification UL 94 V-0
