PC817 2-Channel Optocoupler Isolation Board

This is a 2-channel optocoupler isolation module using PC817 chips. Each channel is electrically isolated and operates independently, making it ideal for isolating signals and voltage levels between microcontrollers and higher-voltage control circuits. Perfect for signal transmission, noise suppression, and voltage control in various automation and electronic applications.

Key Features:

• 2-channel PC817 optocouplers – each channel operates independently
• Voltage isolation – allows low-voltage control of higher-voltage circuits
• Input voltage: 3.6V – 24V DC
• Output voltage: 3.6V – 30V DC
• Jumper cap – enables setting output to high or pull-down state
• Ideal for MCU I/O isolation and noise suppression
• Can drive transistors, MOSFETs, or different voltage interfaces

Applications:

• I/O isolation for microcontrollers
• Noise suppression in switching circuits
• Signal bridging between circuits with different potentials or impedances
• Microcontroller interfacing with higher voltage devices

Notes:

• The input signal ground (GND) is shared between both channels.
• Output ports are electrically isolated and independent of each other.
• When a valid signal is applied to the input, the corresponding output (V and G) becomes active.
• Terminal colors and materials may vary depending on stock.

Specifications:

• Driving Port Voltage: 3.6V – 24V DC
• Output Port Voltage: 3.6V – 30V DC
• Dimensions: 38.3mm x 29.3mm x 12mm
• Mounting: 4 mounting holes (Ø3.3mm)
