The digital two-channel temperature controller TC42-1/220V is a microprocessor device with two 4-digit displays and serves for measuring and regulating temperatures in the range from -99º to +650ºC. The dual-channel temperature controller uses two Pt100 temperature sensors (one for each channel) as a sensing element for measuring the temperature. It has two output relays (one for each channel). The temperature regulation is carried out by two-position method "on/off". The temperature controller is designed for installation in a dashboard (panel montage).


The digital two-channel temperature controller TC42-1 is a compact microprocessor device that serves to measure and regulate temperatures in the range from -99º to +650ºC. In one housing are integrated two independent from each other temperature controllers each of which has one input and one output. The inputs of the temperature controller are designed to work with Pt100 temperature sensors 2-wire, and its outputs are relay contacts. The temperature regulation is carried out by two-position law “on/off”. To prevent flipping through the relay contacts of the outputs when switching, in the process of production is set up a limit to their performance of 0,5 seconds. By the front panel buttons can be set the desired the temperature of regulate (T), hysteresis (h) and the operating mode (Mode) - heating or cooling, and by changing the value of the coefficient (d) can be compensated the error of the measured temperature, which is obtained from the resistance of the connecting cable of the temperature sensors. The temperature controllers are widely used in industrial automation, technological and other processes.

Кратко описание

The two-channel temperature controller TC42-1 is an electronic device that serves for measuring and regulating temperatures in the range from -99º to + 650ºC. The temperature controller uses a Pt100 temperature sensor as a sensitive element for measuring the temperature. The main purpose of the two-channel thermostat is to visualize and regulate the measured temperature by turning on and off the electrical circuit in which it is included.
