Product Description
This module has 8 channels/roads of relays that are isolated by light coupling and meet the safety standard for controlling and loading areas. It uses optical coupling isolation technology.
The module has reliable and stable triggering for the relays. It has a double FR–4 circuit board design with high-end SMT process. It also has indicators for power and relay operation. The relay terminals (C, NC, NO) are easy to wire up through screw terminals.
The module’s inputs are isolated to protect any sensitive control circuitry.
It can be controlled by a variety of microcontrollers such as Arduino, AVR, PIC, ARM and so on.
The use of high-voltage relays reduces the risk of overheating the relay as electromechanical relays limit the current consumption according to 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
IN5: relay module (effective) high-level trigger signal trigger end

IN8: 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 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.
