Description of Relay Module 2 Channel 12V

The 12V Dual Channel Relay Module (Low-Level Trigger) is a reliable solution for controlling high-power AC and DC electrical loads from a microcontroller or development board. It features two independent 10A relays that can switch devices such as lights, fans, motors, pumps, solenoids, and other electrical equipment.

This module uses an Active LOW (Low-Level Trigger) input, meaning each relay is activated by applying a LOW (GND) signal to the corresponding input pin. Built-in back EMF protection and freewheeling diodes help protect the controlling microcontroller from voltage spikes generated by inductive loads. High-quality screw terminals, LED status indicators, and mounting holes make installation quick and convenient for automation, robotics, Arduino, ESP32, Raspberry Pi, PLC, and industrial control projects.


Feature

  • Low-Level Trigger (Active LOW) input control
  • Operating Voltage: 12V DC
  • 2 Independent Relay Channels
  • Relay Rating: 10A @ 250VAC or 10A @ 30VDC
  • Controls AC and DC loads including motors, lights, fans, solenoids, pumps, and other electrical devices
  • Built-in Back EMF Protection
  • Integrated Freewheeling Diodes for controller protection
  • High-quality C, NO, NC screw terminals
  • LED indicators for each relay status
  • Standard header pins for easy microcontroller connection
  • Mounting holes for secure installation

How the Low-Level Trigger Work

This module uses an Active LOW (Low-Level Trigger) control method.

  • Apply LOW (GND) to IN1 → Relay 1 turns ON
  • Remove the LOW signal from IN1 → Relay 1 remains OFF
  • Apply LOW (GND) to IN2 → Relay 2 turns ON
  • Remove the LOW signal from IN2 → Relay 2 remains OFF

The relay is activated only when the corresponding input pin is pulled to GND (LOW). Without a LOW trigger signal, the relay stays in its default OFF state.
