Relay Module 1 Relay 12V 30A

This Relay module adopts a genuine high quality 30A relay. By using a optocoupler isolation chip, the relay has a strong driving ability, stable performance and has a trigger current of 5mA. What makes this relay module great for any project is that it is able to trigger either high or low depending on what you set the onboard jumper to. The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which makes this relay very convenient.

Quick Spec

  • Single Channel
  • Trigger: High/Low
  • Relay Version: 12V
  • Quiescent Current: 5mA
  • Trigger Current: 2 ~ 4mA
  • Dimensions: 72 x 40 x 20mm

Wiring Diagram


  • DC+: Module DC power supply positive (trigger terminal voltage positive)
  • DC-: Module DC power supply negative (trigger terminal voltage negative)
  • IN: Signal trigger terminal (default trigger voltage is the same as power supply)
  • High/low level trigger mode selection, when the jumper is connected with the L terminal, the IN terminal is low level trigger, and when connected to the H terminal, it is triggered high level
  • Normally closed terminal (NC): relay normally closed terminal
  • Common (COM): Relay Common
  • Normally open (NO): The relay is normally open

When the control terminal has a high/low level trigger signal, the relay pulls in, the common terminal is connected to the normally open end, and the device is powered and operates.
