Compact voltage converter module with 8/4/2 isolated channels, each with an independent power indicator and configurable input or output terminals. It provides a 10 mA drive capacity and IIC compatibility for flexible system integration. 3.3V or 5V control signals to drive a 3.6 30V voltage interface. Ideal for electronic engineers, industrial automation designers, and enthusiasts who need voltage matching and signal separation across systems, motor controls, or sensor interfaces. Optocoupler drive terminal 817. Signal voltage: 3.6 24V. Output terminal voltage range: 3.6 30V. Output current is limited to a maximum of 10 mA; total power is constant, and voltage and current are inversely proportional. Use scenarios Microcontroller to higher voltage loads: Use 3.3V or 5V control signals to switch or interface with devices operating up to 30V, while maintaining galvanic isolation to protect the controller. Industrial automation and sensing: Isolated channels prevent ground loops when connecting multiple sensors or actuators to a single control system, improving reliability in 24V environments. Prototyping and testing: Leverage the configurable input/output terminals and multiple isolated channels to separate signals for testing, debugging, or validating disparate subsystems.
