4 Channel Optocoupler Isolated Board Precision and reliable isolation Provides galvanic isolation between input signals and the output power domain. Translates 3.3 V or 5 V logic signals to accurately drive devices operating at 3.6 V to 24 V. Designed to deliver precise control in mixedvoltage environments, improving safety and signal integrity for your projects. Compact, durable design ABS material construction with a compact footprint for easy integration into small or crowded assemblies. Suitable for both hobbyists and professionals who need dependable performance without bulk. Clear performance limits you can rely on Maximum pulse signal frequency is 4 kHz. For signals above this limit, reconsider the application to ensure operation of the voltage isolation module and avoid issues. Flexible control options Jumper cap configurations allow you to set the output as potential or lowoutput to match your design needs. The board supports independent control of the 4th and 817 circuits, enabling simultaneous control of different voltages for enhanced versatility. 23 practical use scenarios Scenario 1: Microcontroller to highervoltage devices Use a 3.3 V or 5 V microcontroller to safely control relays, MOSFETs, or LED drivers that operate at 12–24 V, while maintaining galvanic isolation between the control logic and power load. Scenario 2: Multivoltage project pathways Interface multiple voltage domains in a single project, using isolation to prevent crosstalk and reduce noise, while independently managing the 4th and 817 circuits for disparate voltage needs. Scenario 3: Prototype testing and safety compliance Employ in development and testing environments where isolating the control signal from voltage equipment helps protect sensitive test hardware and users, ensuring predictable behavior within the 3.6–24 V output range.
