Description

The image you provided appears to be an 8-channel optocoupler isolation board, specifically using PC817 optocouplers. These boards are commonly used in electronics projects to provide electrical isolation between different parts of a circuit.

Applications:

Microcontroller Interfacing: Protects microcontrollers from high voltages by isolating the input signals.
Signal Isolation: Used to isolate different parts of a circuit to prevent noise or interference.
Industrial Automation: Commonly used in industrial control systems to interface different voltage levels safely.
Relay Control: This can be used to control relays without directly connecting the control signal to the high-voltage side.

Example Connections:

Inputs: Connect the input signals (e.g., from sensors or other low-voltage devices) to the IN1 to IN8 terminals.
Outputs: The outputs can be connected to relays, microcontroller pins, or other control circuitry that requires isolation from the input signals.
Power Supply: Ensure the board is powered appropriately, following the specifications for voltage and current.

Package Include:

1 x PC817 8-Channel Optocoupler Isolation Board DC.
