This module provides isolation control and voltage conversion for safe, reliable interfacing between low voltage control signals and higher voltage loads. Key features Isolation and voltage conversion: enables safe control of a 3.6 to 30 V load from a control signal in the 3.6 to 24 V range. Drive and load voltages: drive terminal signal voltage 3.6–24 V; output terminal voltage range 3.6–30 V. Output current and power: maximum output current up to 10 mA; total output power is constant, with voltage and current inversely proportional. Control interface: supports 3.3 V or 5 V control signals to operate the 3.6–30 V load interface. Turn on behavior: when the control terminal is energized, the controlled terminal turns on. Performance and compatibility Isolation resilience: photoelectric isolation provides strong anti interference capability. Driver reach: suitable for driving power triodes, MOS transistors, and other circuits that require voltage driving. Relay compatibility: can directly drive low power 24 V relays. Benefits Safe interfacing: galvanic isolation protects control circuitry from voltages and transients. Logic to load compatibility: allows 3.3 V or 5 V control signals to switch loads in the 3.6–30 V range. Noise immunity: isolation reduces the effect of load noise on control electronics. Flexible load options: suitable for relays and voltage driving applications. Use scenarios 1) Microcontroller driven control of a 24 V relay: use a 3.3 V or 5 V logic signal to switch a 24 V relay via the isolation module, keeping the control side separate from the load. 2) voltage drive in automation: isolate a 3.6–30 V load drive such as a power transistor or MOSFET gate from a low voltage control signal. 3) Noise sensitive equipment: employ isolation to prevent load transients and electrical noise from affecting control circuitry in industrial environments. Notes The controlled terminal energizes when the control terminal is energized. The output current is determined by the specific load within the stated maximum of 10 mA; the total power remains constant and voltage and current are inversely related within the operating range.
