PC817 Optocoupler Isolation Board 2/4/8 Channel Voltage Isolation Module Key benefits Independent channels: Each channel operates independently, allowing you to control different voltages at the same time without cross interference. Jumper cap configuration: Determine whether the output terminal is potential output or lowoutput through the included jumper cap for flexible interfacing with your system. PC817 based isolation: Provides voltage isolation between input and output via PC817 optocouplers, improving noise immunity and protecting control circuitry. Scalable channel options: Available in 2, 4, or 8 channel versions to suit small to larger projects. Easy integration: Designed for straightforward wiring with PC817 optocoupler isolation boards, simplifying setup in existing systems. What it does Function: Optocouplerbased isolation module that separates control signals from voltage or noisy circuits, while allowing independent multichannel operation. Compatibility: Specifically built around PC817 optocouplers and the 2/4/8 channel configurations to match common lowvoltage control interfaces with higher voltage outputs. Performance: Provides reliable voltage isolation per channel, supporting simultaneous, multivoltage control with reduced risk to the control side. 23 practical use scenarios Microcontroller to voltage load interface: Use the 2/4/8 channel board to isolate MCU or digital logic output from voltage actuators or relays, reducing risk from voltage spikes and ground noise. Industrial automation: Isolate sensors and controllers in environments with electrical noise or potential ground loops, improving signal integrity and equipment protection. Multichannel testing and prototyping: Run several circuits in parallel at different voltages from a single PC817 isolation board, enabling efficient bench testing and validation.
