12V 2 Channel Relay Module with Optocoupler

This 2 Channel 12V Relay Module with Optocoupler fulfills the safety guideline as control regions and load region have the isolation groove. Optical coupling isolation module.

The setting off of the 2 Road/Channel Relay Module is solid, more steady. The twofold FR 4 circuit board configuration, top of the line SMT process. It has power and relay activity guidelines. Relays terminals (C, NC, NO) are available through screw terminals which makes wiring up the board extremely simple.

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

A wide scope of microcontrollers like Arduino, AVR, PIC, ARM, etc can control it.

The utilization of such high-voltage relay takes out the gamble of warming up of the relay as electromechanical relay limit the current consumption as per a voltage rating.

Module interface:

The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative
IN1: relay module (effective) high-level trigger signal trigger end
IN2: relay module (effective) high-level trigger signal trigger end

Meaning of High level and Low-level

1. 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.
2. Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
