Control Signals

Here’s how you can connect our SCR power controllers based on different control signals. Each control method is designed for ease of use and ensures efficient and safe power regulation for your heating systems:

4-20mA
This is one of the most common methods for regulating heating power. For detailed instructions on how to connect the SCR power controllers with a 4-20mA temperature controller, please refer to our blog on 4-20mA control signal connection.

0-5V / 0-10V
If you are using a DC voltage signal (0-5V or 0-10V) to control heating power, our controllers support this input. For the wiring details, check our guide on using DC voltage inputs.

Control Signal: Potentiometer
A potentiometer can also be used to adjust the heating power. Learn how to wire the SCR power controllers with a potentiometer as an input signal in our potentiometer control wiring guide.

P+

Reference power supply +5V: Feed reference for external potentiometers

2

AI1

Current analog input port 1: DC 4-20 / 0-20 mA (input impedance 125Ω), with 4-terminal GND to form an input loop.

3

AI2

Voltage analog input port 2: 0~5V input/potentiometer input (center tap)/DC0~10V, and GND form the input circuit. 0~5V 0~10V no need to connect P+
