1pcs PC817 Optocoupler Isolation Board Voltage Converter Adapter Module 3.6-30V Driver Photoelectric Isolated Module

Isolation Control and Voltage Conversion Module: A Versatile Signal Isolation and Driving Solution

- In practical work, this module can play an important role when there are scenarios requiring isolation control and involving voltage conversion. It can realize 3.3V or 5V control signals to control interfaces with voltage levels ranging from 3.6V to 24V — when the control end is turned on, the controlled end will also be turned on, meeting the needs of signal isolation and driving in various scenarios.

Core Functions and Advantages

- Strong anti-interference ability: Adopts photoelectric isolation technology to effectively isolate interference signals and ensure control stability.

Flexible driving capability: Can drive high-power triodes, MOS tubes and other devices that require high-voltage driving, and can also directly drive small-power 24V relays to work.

- Signal frequency limitation: Suitable for pulse signals, but limited by the performance of 817, it only supports control signals below 4KHZ. Control signals higher than this frequency will cause the module to work abnormally.

Module Parameters

- Driver signal voltage: 3.6-24V

- Output voltage range: 3.6-30V (the output current depends on the specific situation; due to the fixed total power, voltage and current are inversely proportional)

- Output mode switching: The output terminal can realize high potential output or pull-down output through a jumper cap.

- Channel independence: The 4 channels of 817 on the board are independently designed, which can realize simultaneous control of different voltages.

- Dimension specifications: Length: 48mm; Width: 38mm; Long-side hole distance: 42mm; Wide-side hole distance: 32mm

- With its core functions of isolation control and voltage conversion, as well as flexible driving capability, this module is suitable for various electronic equipment scenarios that require signal isolation and high-voltage driving.
