Product Parameter

Input/output channels: four

Input voltage: 3.3V or 5V (IN1-IN4)

Maximum output voltage: ≤ 24V(OUT1-OUT4)

Controlled power supply voltage: ≤ 24V(HVCC HGND)

Product Descriptions

This module is a signal voltage isolation adapter board that separates the low voltage and high voltage parts. It can control 4 high voltage channels, 4 IN input terminals, 4 OUT output terminals, and HVCC HGND controlled power supply terminal through a microcontroller. This module can be used to control the high and low level signals of 12V or 24V relay modules to trigger conduction and disconnection, and can also be applied to other types of equipment.

Connect the IN1/IN2/IN3/IN4 signal terminals to the IO ports of the microcontroller or Arduino

IN1/IN2/IN3/IN4 respectively control the corresponding output channels OUT1/OUT2/OUT3/OUT4

HVCC is connected to the positive pole of the supply voltage, HGND is connected to the negative pole of the supply voltage

Example of use:

When IN1-IN4 inputs high and low level signals, and the HVCC supply voltage will be placed on the high and low voltage outputs of OUT1-0UT4 pins
