Industrial 4-Ch DC Monitoring Module, 16-bit High-Precision Acquisition, Supports Voltage and Current Measurement, Modbus RTU Protocol, with Various Isolation and Protection Circuits

Features at a glance This product is an industrial-grade DC monitoring module supporting 4-channel measurement. Adopts Modbus RTU protocol with built-in protection circuits such as power isolation, optocoupler isolation, resettable fuse, and TVS. ● Configurable device address (1~255), multi devices can be cascaded on RS485 bus. ● Onboard voltage regulator, supports 7~36V wide range power supply. ● Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. ● Onboard optocoupler isolation, allows signal isolation, high reliability, strong anti-interference. ● Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic. ● Onboard 0.002Ω ±1% current sense resistor with 16-bit high-precision acquisition, capable of bidirectional current measurement. ● Supports voltage measurement up to 36V and current measurement up to 8A, with direct power measurement. ● Rail-mount case design, supports stacking combination, easy to install and safer to use. ● 3x LEDs for indicating the MCU status and signal transceiving status.
