PC817 Dual Channel Optical Isolator Board

This is a dual-channel optical isolation unit that utilizes PC817 chips. Each channel operates independently and is electrically isolated, making it ideal for signal and voltage level isolation between microcontrollers and high voltage control circuits. It is perfect for signal transmission, noise suppression, and voltage control in various automation and electronics applications.

Main Features:

• PC817 dual-channel optical couplers - Each channel operates independently
• Voltage isolation - Allows low voltage control of higher voltage circuits
• Input voltage: 3.6 volts – 24 volts DC
• Output voltage: 3.6 volts – 30 volts DC
• Jump cap - Allows output to be set to a high or low state
• Ideal for isolating MCU I/O and suppressing noise
• Can drive transistors, MOSFETs, or different voltage interfaces

Applications:

• Input/output isolation for microcontrollers
• Noise suppression in switching circuits
• Signal linking between circuits with different potentials or impedances
• Linking the microcontroller to high voltage devices

Notes:

• The input ground (GND) signal is shared between the two channels.
• The 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.
• The colors and terminal materials may vary depending on the stock.

Specifications:

• Drive port voltage: 3.6 volts – 24 volts DC
• Output port voltage: 3.6 volts – 30 volts DC
• Dimensions: 38.3 mm × 29.3 mm × 12 mm
• Installation: 4 mounting slots (Ø3.3 mm)
