Temperature controller for DIN-rail TC4-1L/220V
T=(-99°...+650°C), Us=220Vac, Output 4A/220V, 86x70x58mm
The single-channel digital TC4-1L/220V temperature controller for DIN-rail mounting is a microprocessor device with a 4-digit display and serves for measuring and regulating temperatures in the range from -99º to +650ºC. The temperature controller uses a Pt100 temperature sensor as a sensing element for measuring the temperature. It has one relay output. The temperature regulation is carried out by two-position method "on/off".
FEATURES
The digital single-channel temperature controller TC4-1L is designed for mounting on an M35 DIN-rail. It is a compact microprocessor device which is used for measuring and regulating temperatures within the range from -99º to +650ºC. The temperature controller has one input and one output. The input of the temperature controller is designed for operation with a 2-wire or 3-wire temperature sensor Pt100, and his output is a relay contact. The temperature regulation is carried out in a simple two-position law of control (ON-OFF). To avoid clicks of the relay contact at output switching, there is a factory set limit of its operation speed 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 sensor. The temperature controller is used for automation of industrial, technological and other processes.

Short description
The single-channel TC4-1L digital temperature controller 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 single-channel temperature controller is to visualize and regulate the measured temperature by turning on and off the electrical circuit in which it is included.
