DC20D
Two-channel temperature controller
"DC=Double Controller" is in fact two temperature controllers placed in one housing with the possibility of any configuration of inputs and outputs and linking both controllers. The device has 2 inputs and 2 control outputs that can operate in heating or cooling mode. Installation in an electrical switchboard on a DIN TH-35 rail.

If you do not know which regulator to choose, please read the article.
Basic information:
- 2 REGULATORS in one housing
- mounting on a DIN TH-35 rail
- 2 measurement inputs
- 2 control output
- Temperature display T1 and T2
- mathematical functions (average, differential measurement)
- the possibility of connecting REGULATORS with each other (e.g. OUT1 = on, when OUT2 = off)
- digital input (normally open or closed)
- built-in sounder (buzzer)
The regulator has a digital temperature readout and the function of calibration of indications. The value from sensor T1 and T2 is displayed alternately every 3 seconds. You can set the controller to display only one reading.
The built-in sounder can be set to signal activation of outputs and alarm states.
The digital input can function as an alarm input or a manual output control mode. It can signal a system failure after the activation of an external pressure switch or STB temperature limiter connected to the digital input. In the event of a failure, it will disconnect the entire system with the ability to maintain the failure state until manually reset by pressing the button.
The regulator is equipped with a high-power relay output 1 20A (maximum resistive load 4500W) and Output 2 with a maximum load of 8A. Installation in an electrical switchboard on a DIN TH-35 rail.
