In industrial automation control systems, IO data acquisition terminals connect to field devices (PLCs, sensors, CNC machines, industrial robots, etc.) to collect data types such as digital inputs (DI), digital outputs (DO), analog inputs (AI), and analog outputs (AO)—enabling real-time monitoring and intelligent management of production processes.

WideIOT's IO data acquisition terminal is an industrial-grade smart terminal designed for Modbus I/O data acquisition, LoRa data transparent transmission, and 4G cloud connectivity. It supports LoRa wireless transmission, 4G uplink to cloud platforms, multi-channel IO data acquisition, Modbus RTU protocol, and wireless RS-485 transparent transmission. It offers multiple configurable channels of analog inputs, analog outputs, digital inputs, and digital outputs, enabling rapid on-site data acquisition setup.

Application Scenarios

A host system (upper computer) reads and controls the IO of the IO data acquisition terminal (lower computer) via a serial port.
A host system reads the IO of the IO data acquisition terminal via LoRa wireless communication.
A host system reads the IO of the IO data acquisition terminal and data from connected PLCs via LoRa.
A cloud platform reads the IO of the WD240 terminal and data from connected PLCs via LoRa wireless and Internet connectivity.

Key Functions

Remote Monitoring and Control – Users can monitor and control the IO data acquisition terminal and connected field devices in real time from remote locations, improving system flexibility and convenience.
Enhanced Scalability – The IO data acquisition terminal offers multiple interfaces and connectivity options, supporting connection to various types of sensors and actuators. Users can select the optimal communication method based on actual requirements.
Reduced Maintenance Costs – Through the Remote Maintenance Tunnel, users can perform remote programming, debugging, and program upload/download—reducing the frequency and cost of on-site maintenance.
