Wiring Diagram
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:
- Control Signal: 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 . - Control Signal: 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 . - 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 .
Human-Machine Interface
AIGOODELE SCR power controllers feature a user-friendly HMI with a clear LCD display that allows easy monitoring of real-time status and quick adjustments. Parameters such as control modes, output power, and protection settings can be configured directly from the display. Designed for simplicity, the interface provides precise control over heating applications, making it easy to operate. For more details, check out our .
