The RTU acquisition module is a remote measurement and control unit device. The measurement and control terminal integrates A/D functions and I/O functions and is responsible for monitoring and controlling on-site signals and industrial equipment. The RTU acquisition module outputs control signals and controls the relay output, thereby achieving remote control and telemetry of remote equipment.
Compared with the commonly used programmable controller PLC, RTU usually has excellent communication capabilities and larger storage capacity, is suitable for harsher temperature and humidity environments, and provides more computing functions.
ZHC4921 is an industrial-grade RTU acquisition module , controlled by a 16-bit low-power microcontroller, providing 4 switching inputs, 4 switching outputs, 4 analog inputs and 1 RS485 bus. Supports local logic processing operations, automatic collection and active reporting, Modbus RTU/TCP adaptation, automatic calibration threshold reporting, configuration software docking, dry and wet node IO detection and other special functions, supports one-to-one, many-to-one network, configuration software The interface window is visualized, allowing users to connect, debug, and configure equipment on-site or remotely. It can be widely used in power systems, industrial monitoring, traffic management, environmental monitoring, meteorology, water conservancy, coal mining, petroleum, new energy and other industries.
