PC817 2-Channel Optocoupler Isolation Board

The PC817 2-Channel Optocoupler Isolation Board provides optical signal isolation for interfacing control circuits operating at different voltage levels. Its two independent PC817 channels allow you to handle two control signals with different voltages on the same board.

Key Features

• Two independent channels: Use each PC817 optocoupler channel for a separate signal-isolation task.
• Control-signal isolation: Interface a microcontroller or another device's I/O with an external control circuit, subject to the module's voltage requirements.
• Different voltage levels: Supports a driving-side signal voltage of 3.6–24V and an output-side voltage of 3.6–30V.
• Jumper-selectable output: Configure the output for high-potential or pull-down operation using the jumper cap.
• Flexible interfacing: Use in control interfaces involving external transistors, MOSFETs, or devices operating at different voltage levels.

Specifications

• Optocoupler: PC817
• Number of channels: 2, independently controlled

• Output-port voltage: 3.6–30V
• Output configuration: Jumper-selectable high-potential or pull-down output

Before Connecting

Check the board's terminal markings, jumper position, and voltage requirements before wiring. Confirm that your controller's I/O signal meets the stated driving-voltage range. This module is intended for signal isolation and interfacing, not as a DC-DC power converter.
