5V 8 Channels Relay, Module High and Low, Triggering Optocoupler, Isolation Relay Module, PLC Signal Amplifier, Board

This 8 channel 5V  relay control board module with optocoupler modules is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.

The inputs of the 8 Channel 5V  Relay Module are isolated to protect any delicate control circuitry.

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.

Note: On the high level and low level-triggered mode, friends who do not understand, have a look

• 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  8-channel relay module connection.

Features:

1. High impedance controller pin
