4 Channel Isolated 5V 10A Relay Module with Low Level Trigger Optocoupler

Description

This 4 Channel Relay Module (with light coupling) 5V module meet the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module.

The triggering of 4 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 5V Relay Module are isolated to protect any delicate control circuitry.
A wide range of microcontrollers such as Arduino, AVR, PIC, ARM 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.
