12V 4 Channel Isolated Relay Module optocoupler (with Light Coupling)

12V 4 Channel Isolated Relay Module optocoupler (with Light Coupling)

This 4 Road/Channel Relay Module (with light coupling) 12V module 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 12V 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 the relay as electromechanical relays limit the current consumption in accordance with a voltage rating.

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 the 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. Note: The available relay module types are: JQC-3FF-S-Z, JQC3F-12VDC-C, and FL-3FF-S-Z. You may get any of it randomly.
