4-Channel 12V Relay Module With Opto Isolated Input

New 4-Channel 12V Relay Module With Opto Isolated Input

his 4 Road/Channel Relay Module (with light coupling) 12V module meet the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module.

The triggering of 4 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 4 Channel 12V Relay Module are isolated to protect any delicate control circuitry.

A wide range of microcontrollers such as Arduino, AVR, PICARM and so on can control it.

The use of such high-voltage relay eliminates the risk of heating up of the relay as electromechanical relay limit the current consumption in accordance with a voltage rating.

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 the 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.
