IEC104 Edge I/O Module BE190Pro

No.BE190Pro
The IOy BE190Pro I/O module integrates PLC, I/O, and protocol gateway functions into a compact, industrial-grade device. With native support for IEC 60870-5-104, MQTT, Modbus TCP, and OPC UA, it ensures seamless, secure communication across SCADA systems, cloud platforms, and industrial controllers. Its modular architecture, high-precision data acquisition, and built-in edge computing make it ideal for energy automation, smart grids, and other critical infrastructure requiring real-time monitoring, control, and interoperability.
Description
The BE190Pro is a multifunction industrial-grade remote I/O module from the IOy series, engineered for power automation and critical infrastructure applications. With native support for IEC 60870-5-104, MQTT, Modbus TCP, and OPC UA, it enables seamless communication between SCADA systems, industrial controllers, and cloud platforms.

Built to withstand harsh environments, the BE190Pro features electrical isolation, EMC/EMI compliance, wide -45 to 80°C temperature tolerance, and an independent hardware watchdog for stable 24/7 operation. Its modular architecture, high-precision I/O, and edge computing capabilities make it ideal for intelligent substations, distribution automation, grid monitoring, and new energy power generation.


Key Features

  • Versatile Communication: Dual 10/100M Ethernet ports enable cascading and concurrent communication via IEC104, MQTT, Modbus TCP, and OPC UA, ensuring secure and interoperable data exchange across IT/OT layers.
  • Precise Data Acquisition: One isolated RS485 port enables data collection from Modbus RTU slave devices, while modular I/O expansion allows for flexible sensor/actuator integration.
  • Edge Logic & Control: Built-in web server enables quick register mapping, logic configuration, and real-time control, serving as a cost-effective PLC alternative.
  • Remote Configuration & Maintenance: Supports fast web-based configuration and is integrated with BLRAT (Beilai Remote Access Tool) for remote firmware upgrades and parameter tuning.
  • Modular & Scalable: Offers 1–3 I/O expansion slots for tailored deployment in diverse industrial environments including energy systems, substations, and IIoT infrastructures.
BE190Pro ensures reliable performance in harsh environments, making it ideal for smart grid, energy automation, and industrial digital transformation projects.


Typical Application Areas
  • Smart Substation Automation Monitoring: Collects switch status and analog data (current, voltage, power) from substations and uploads it to SCADA via IEC 60870-5-104, while sharing real-time status via OPC UA or MQTT for parallel IT/OT visibility.
  • Distribution Network Automation Terminals: Installed in RMUs and switching stations, collects line signals and fault indicators, and synchronizes data with control centers via IEC104 and Modbus TCP, ensuring reliability and interoperability.
  • New Energy Power Plant Integration: Aggregates inverter, transformer, and weather data from solar and wind farms, converts it into standard IEC104 for grid-level systems and MQTT/OPC UA for cloud-based monitoring platforms.
  • Power Grid Dispatch Data Gateway: Bridges field devices using Modbus TCP with dispatch centers via IEC104, enabling seamless protocol conversion and real-time data synchronization across systems.
  • Power System Fault Detection and Protection: Acts as an edge node for monitoring critical faults and protection triggers in the power grid, pushing alerts via MQTT while ensuring SCADA compliance with IEC104.
  • Smart Grid Monitoring: Continuously gathers operational data from distributed sensors and devices across the power network, using OPC UA and MQTT for open, scalable data access and visualization.
  • Energy Storage System Monitoring: Tracks battery status, charge/discharge cycles, and environmental conditions, providing flexible reporting over Modbus TCP for local controllers and MQTT/OPC UA for remote management.
  • Remote Equipment Maintenance: Enables remote diagnostics and fault analysis of generators, transformers, and field devices through IEC104 for grid SCADA and OPC UA for digital maintenance platforms.
  • EV Charging Station Management: Integrates charging data such as voltage, current, and load status, supporting backend platforms with real-time updates via MQTT or OPC UA, while ensuring grid compliance with IEC104.


Ordering Guides
Users can select 1-3 Y series IO boards according to their needs, such as BL190 with 3 Y11 (8DI) can be composed of 24DI Modbus TCP IO module, and also supports mix and match such as BL190 with Y11 (8DI), Y31 (4AI), Y52 (2PT) can be combined into 8DI + 4AI + 2PT Modbus TCP IO Module.
