PC817 4 Channel Optocoupler Isolation Module

This module is used for isolation control and voltage conversion. It can control a voltage interface ranging from 3.6V to 30V using either 3.3V or 5V. Once the control terminal is activated, the controlled terminal will also be activated.

The module features photoelectric isolation with strong anti-interference capabilities. It can drive high-power triacs, MOSFETs, and other applications requiring high voltage drive, as well as directly drive low-power 24V relays. Note that for pulsed signals, the 817 limit is 4kHz or lower. If the control signal frequency exceeds 4kHz, this module may not operate correctly.

Technical Specifications

• Driver Terminal Signal Voltage: 3.6V - 24V
• Output Terminal Voltage Range: 3.6V - 30V (Output current is situation-dependent, but does not exceed 10mA; total power is constant, with voltage and current being inversely proportional)
• High or Low Potential Output: Can be determined with a jumper wire
• Channels: 4 independent PC817 channels, allowing simultaneous control of different voltages
• Dimensions: 48mm x 38mm

Package Included:

• 1 x PC817 4-Channel Optocoupler Isolation Module
