817 Optocoupler 8-Channel Photoelectric Isolation Module

The OKY2122 is an 8-channel optoisolator module designed to provide galvanic isolation for electrical circuits. It uses PC817 optocouplers to safely transmit signals between isolated sections, protecting sensitive components from high-voltage interference and noise.

Key Features
- 8 Independent Channels: Allows for simultaneous control of multiple devices, which can operate at different voltages.
- Voltage Level Shifting: Enables control of higher-voltage circuits (up to 30V) using low-voltage logic signals (from 3.6V).
- Configurable Output: Each channel's output can be configured using jumpers for either a high potential or a pull-down to ground (low potential) state.
- Reliable Isolation: Built with PC817 optocouplers to ensure effective signal separation and circuit protection.

Applications
This module is ideal for interfacing low-voltage microcontrollers with higher-voltage actuators. It is well-suited for safely controlling devices such as motors and relays while protecting the main control board from electrical noise and potential damage.
