This 8 channel optocoupler isolation board provides reliable signal isolation and voltage conversion for various electronic control applications. It effectively avoids electrical interference between control circuits and high-power loads, ensuring stable system use
Connect your 3.3V or 5V control signals to the input terminals. The photoelectric isolation circuitry transmits signals without electrical connection to the output side. Use the jumper cap to select either high level or pull down output mode according to your application requirements. The independent channels allow simultaneous control of different voltage devices up to 30V. This module is ideal for driving MOSFETs, power transistors, and low-power 24V relays in industrial automation and electronic projects
