DC 12V 2 channel relay module with optocoupler

DC 12V 2 channel relay module with optocoupler 

This 2 Road/Channel Relay Module (with light coupling) 12V module meets the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module.

The triggering of the 2 Road/Channel Relay Module is reliable, more stable. The double FR – 4 circuit board design, high-end SMT process. It has power and relay operation instructions. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy.

The inputs of the 2 Channel 12V Relay Module are isolated to protect any delicate control circuitry.

Meaning of High level and Low-level

High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.

Features :

Equipped with high-current relay 10A@250VAC / 10A@30VDC

It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc

High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection

A freewheeling diode to protect your microcontroller
