1 Channel Relay Module, 30A with Optocoupler, isolation 12V Supports, High And Low Trigger,(with Guide Rail)

This 1 Channel Relay Module, 30A with Optocoupler, isolation 12V Supports module utilizes a high-power 30A relay that can be triggered via the optoisolator with a 12V input. What makes this module ideal for any project is its ability to be triggered either high or low, depending on the onboard jumper setting. The output features robust terminal power connectors, which make load connections simple and convenient.

The power supply and relay instructions, lit, a disconnect are off. The input signal, signal, common Terminal and start conducting. It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load.

A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it. This module comes with a Guide rail situated on the backside of it so we can adjust the module to a superior location.

High level and low level-triggered mode Function:

• High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away;
• Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way  1-channel relay module connection.

Pin Out:

• 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

Package Include :

• 1 x 1 channel 12V 30A relay control board module (Guide rail)
