PC817 8-Channel Optocoupler Isolation Module

This 8-channel optocoupler isolation module uses PC817 optocouplers to provide electrical isolation between input and output circuits. Each channel operates independently and can be used to interface microcontrollers with high-voltage devices, suppress switching noise, and transmit signals across different voltage domains safely.

Key Features:

• 8 independent PC817 optocoupler channels – ideal for multiple signal isolations
• Wide input voltage range: 3.6V – 24V DC
• Output voltage range: 3.6V – 30V DC
• Safe electrical isolation between low-level logic and high-voltage devices
• Jumper selectable output mode: high level or pull-down
• Easy interfacing with microcontrollers, Arduino, PLCs, and other digital systems

Applications:

• I/O signal isolation for microcontrollers
• Safe interfacing with high-voltage circuits
• Noise suppression in industrial control systems
• Signal conversion and protection
• Switching different voltage level devices using digital IO

Specifications:

• Input Voltage: 3.6V – 24V DC (per channel)
• Output Voltage: 3.6V – 30V DC (per channel)
• Optocoupler Type: PC817
• Channels: 8
• Mounting Holes: 4 holes for secure installation

Notes:

• Input and output grounds are electrically isolated.
• Terminals may vary in color depending on stock availability.
• Each channel operates independently, allowing mixed voltage control.
