PC817 Optocoupler Isolation Module 2-Channel
The PC817 2-Channel Optocoupler Isolation Module is a photoelectric isolation board designed to protect sensitive electronic devices from electrical noise, voltage spikes, and ground loop interference. By using two independent PC817 optocouplers, the module transfers signals through light rather than a direct electrical connection, providing safe isolation between input and output circuits. This makes it ideal for interfacing low-voltage controllers with higher-voltage devices.
This module supports both voltage conversion and signal isolation, allowing 3.3V or 5V microcontrollers to control devices operating at different voltage levels. Each channel operates independently, enabling simultaneous control of separate circuits with different voltages. The onboard jumpers allow the output configuration to be changed between pull-up and pull-down modes, increasing flexibility in automation, industrial control, and embedded system applications.
