24V 4 Channel Isolated Relay Module optocoupler (with Light Coupling)

24V 4 Channel Isolated Relay Module optocoupler (with Light Coupling)

This 24V 4-Channel Relay Module (with Light Coupling) meets the safety standard as control areas and load areas have the isolation groove. Optical coupling isolation module.

The triggering of the 4 Road/Channel Relay Module is reliable, and 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 4 Channel 24V 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 a high-voltage relay eliminates the risk of heating up the relay as electromechanical relays limit the current consumption in accordance with 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
IN3: relay module (effective) high-level trigger signal trigger end
IN4: relay module (effective) high-level trigger signal trigger end

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.
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.
