4PCS PC817 4-Channel Optocoupler Isolation Board, 3.6-30V Photoelectric Isolated Voltage Converter Adapter Module with Driver Circuit High-Efficiency Signal Transmission

Module Parameters:1. Signal voltage at the driving end: 3.6-24V2. Output terminal voltage range: 3.6-30V (the output current depends on the specific situation, but the maximum is not 10MA, the total power must be inversely proportional to the voltage and current)3. Through the jumper cap, the output terminal can be realized whether the output is high potential output or pull down the output.4. The 4 channels 817 on the board are independent, which can realize simultaneous control of different voltages5: Board size: length: 48mm; Width: 38mm; Long side hole spacing: 42mm; Wide side hole spacing: 32mmOthers: This module is used when there is a need for isolation control and voltage conversion in actual work.It can realize 3.3V or 5V to control the interface of 3.6---24V voltage level, and after the control end is turned on, the controlled end will also be turned on.

• Isolation and Voltage Conversion:Achieve 3.3V/5V to 3.6-30V voltage conversion through optocoupler isolation, eliminating ground loop interference while maintaining signal integrity between control (3.6-24V) and load circuits.
• Multi-Device Compatibility:Directly drive 24V relays or control high-power triodes/MOSFETs with 10mA maximum output current, Supports proportional voltage-current operation within 3.6-30V range
• Flexible Output Configuration:Select high/low potential output modes via jumper cap with four independent channels for simultaneous control of multiple voltage levels (3.6-30V supported).
• Pulse Signal Compatibility:Operates reliably with ≤4KHZ pulse signals (critical notice: inputs exceeding 4KHZ cause malfunction) while maintaining galvanic isolation between control and load terminals.
• Plug-and-Play Integration:Instant signal transmission activates load circuit when control terminal powers on, supporting rapid integration with microcontrollers and industrial control systems.
