BACnet/IP Edge I/O BA190Pro

No.BA190Pro
The IOy BA190Pro I/O module combines the functions of a PLC, I/O module, and protocol gateway into one compact, industrial-grade device. With native support for BACnet/IP, MQTT, Modbus TCP, and OPC UA, it enables seamless data exchange between building automation systems, cloud platforms, industrial controllers, and enterprise software. Its modular architecture, high-precision data acquisition, and built-in edge computing make it a powerful solution for smart buildings, energy management, HVAC, and integrated IIoT applications
Description
The IOy BA190Pro is an industrial-grade, multifunction programmable remote I/O module designed for smart buildings and intelligent infrastructure. Combining BACnet/IP, MQTT, Modbus TCP, and OPC UA protocols in one device, it enables seamless communication across building automation, cloud platforms, industrial controllers, and enterprise systems.
Built to withstand harsh environments, the BA190Pro features electrical isolation, EMC/EMI compliance, wide operating temperature (-45 to 80°C), and an independent hardware watchdog for long-term stability. Its modular I/O expansion, precise data acquisition, and edge computing capabilities make it a powerful, interoperable solution for energy management, HVAC control, and integrated building operations.


Key Features
  • High Cost-Performance: Reduces system cost by up to 80% compared to traditional PLC + I/O + protocol gateway combinations.
  • Versatile Communication: Dual 10/100M adaptive Ethernet ports support multi-protocol communication with BACnet/IP for building systems, MQTT for cloud connectivity, Modbus TCP for industrial integration, and OPC UA for secure, real-time enterprise interoperability.
  • Data Acquisition: One isolated RS485 port supports Modbus RTU master mode, enabling data collection from smart meters and field devices for protocol conversion and upstream integration.
  • Logic Control: Built-in web server allows fast implementation of register operations and logic control, replacing traditional PLCs in HVAC, lighting, and access systems.
  • Remote Configuration & Maintenance: Web-based setup and the built-in BLRAT remote access tool simplify remote configuration, firmware upgrades, and troubleshooting.
  • Flexible I/O Expansion: Offers 1 to 3 modular expansion slots to support DI, DO, AI, AO, and more—suitable for diverse industrial and building automation scenarios.
  • Industrial Reliability: Withstands harsh environments through electrical isolation, EMC/EMI compliance, and wide temperature support (-45 to 80°C), with an independent hardware watchdog for long-term stability.


Typical Application Areas
  • Smart Manufacturing and Industrial Automation: BA190Pro serves as a multi-protocol remote I/O extension for PLCs, connecting sensors and actuators on the production line. Through Modbus TCP and OPC UA, it enables real-time equipment monitoring and control, supporting predictive maintenance and system interoperability.
  • Building Automation and Smart Facilities: With native BACnet/IP support, BA190Pro easily integrates with BMS platforms for monitoring and controlling lighting, HVAC, access control, and energy systems—improving building efficiency, safety, and occupant comfort.
  • Agriculture and Environmental Management: Utilizing MQTT for cloud communication and Modbus TCP for local sensor interfacing, BA190Pro enables precision control of temperature, humidity, irrigation, and ventilation for smart farming and livestock operations.
  • IoT-Based Environmental Monitoring: As an edge I/O device, BA190Pro collects environmental data (e.g., air quality, gas, temperature, humidity) via local RS485 or I/O interfaces, then uploads it securely to cloud platforms through MQTT or OPC UA, enabling real-time analytics and alerts.
  • Energy Storage System Monitoring: By interfacing with smart meters and BMS devices, BA190Pro gathers parameters such as voltage, current, SOC, and temperature, then transmits data via OPC UA to SCADA systems and via MQTT to cloud platforms for remote supervision.
  • Robotic Arm Control and Signal I/O: Acts as an intelligent I/O interface between robot controllers and external sensors/actuators, supporting real-time data exchange over Modbus TCP or OPC UA, and enhancing flexibility through logic control capabilities.
  • Subway and Metro Infrastructure Monitoring: Connects to vibration, temperature, and equipment status sensors in stations. With MQTT and BACnet/IP, BA190Pro enables unified monitoring across OT and IT networks, improving operation and maintenance efficiency.
  • Wind Power and Renewable Energy Monitoring: Supports remote acquisition of wind turbine metrics such as RPM, wind direction, and generator status via Modbus TCP or RS485, and uploads data to cloud or SCADA systems via MQTT/OPC UA for centralized O&M.


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.
