Seven functions in one device

The new TS 2125 2-channel temperature switch combines a total of seven functions in one device and is safe, clear, and easy to use. The multi-talent can be used independently, but also as a replacement for defective mechanical thermostats or digital thermometers.

Equipped with four potential-free relays, the TS 2125 is suitable for all applications requiring temperature monitoring and control in heating or cooling mode. Seven operating modes (some with convenient alarm function) characterize the device: thermometer and thermoswitch for each channel, temperature difference controller, circulation pump control, and manual operation.

A metal temperature sensor included in the package and equipped with a mounting bracket reliably records measuring ranges from -55 to 125.0 °C with a resolution of 0.1 °C in the core area and +/- 2 °C in the peripheral areas - both outdoors, on surfaces, and in non-aggressive gases. The 2 m long, pluggable connection cable can optionally be extended to 50 m.

However, the device not only impresses with its functionality and measuring accuracy but is also safe to use: sensor short-circuits and sensor interruptions are detected immediately. In addition, the TS 2125 has a separate min/max alarm setting - if the temperature is outside the set window, a relay can be switched after an adjustable delay time of 0 to 8 hours per channel, for example, for an alarm message. An internal alarm beeper, which can also be switched off if necessary, emits a warning signal depending on the setting (sensor error).

The switch-on and switch-off temperature, the current temperature, the setting parameters, and the min/max value are clearly shown on the two-line blue display. LED indicators signal relay on, alarm, and sensor error.

All operating parameters are freely adjustable, as is the hysteresis.
