RS485 4-Channel DC Detection Module Modbus RTU 16-Bit for Simultaneous Current Output DC 7-36V

Supports setting device addresses (1~255) to cascade multiple devices via RS485 bus.Onboard voltage regulator chip supports a wide voltage supply range of 7V to 36V.Onboard integrated power isolation provides a stable isolation voltage, and no additional power supply is required at the isolation terminal.Onboard optocoupler isolation enables signal isolation, offering high reliability and strong anti-interference capabilities.Onboard resettable fuses and TVS (transient voltage suppressor) effectively suppress surge voltages and transient voltage spikes in the circuit, providing overcurrent and overvoltage protection, as well as lightning and static electricity protection.Onboard 0.0022 1% sampling resistor, 16-bit high-precision acquisition, capable of measuring bidirectional current.The maximum voltage measurement capability is 36V, the maximum current measurement capability is 8A, and direct power measurement is supported.The rail-mounted housing design supports stacking and combination, making installation convenient and safer to use.Three external LED indicators are provided for easy viewing of MCU status and signal transmission/reception status.Color: As ShownMaterial: plasticPackage Contents:1*Modbus RTU ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
