BA190/BA190Pro are industrial Ethernet I/O modules supporting BACnet/IP, Modbus, MQTT, OPC UA. With flexible I/O expansion and -40~85℃ reliability, they enable seamless cloud/SCADA integration for building/industrial automation.
Case Details
In building automation and industrial scenarios, a common headache is dealing with fragmented protocols and rigid I/O interfaces. Modbus-enabled sensors, MQTT cloud platforms, OPC UA-based SCADA systems—each operates in its own "language," while traditional I/O modules often lack multi-protocol support, making integration tedious and costly.
Enter the BLIIOT BA190Pro Ethernet I/O Module—a game-changer designed to unify Modbus, MQTT, and OPC UA protocols, while offering flexible Ethernet-based I/O expansion. Tailored for building automation, smart manufacturing, and energy management, it bridges protocol gaps and adapts to diverse data acquisition/control needs, turning complexity into simplicity.
Core Value: Ethernet I/O + Multi-Protocol Unification
The
BA190Pro’s strength lies in its seamless integration of Ethernet connectivity, versatile I/O expansion, and native support for Modbus, MQTT, and OPC UA—addressing two critical pain points in automation: protocol incompatibility and I/O inflexibility.
1. One Module, Three Key Protocols—No More Workarounds
The BA190Pro natively supports Modbus, MQTT, and OPC UA, eliminating the need for additional protocol converters:
- Modbus Compatibility: Its isolated RS485 port works as a Modbus RTU master, easily collecting data from smart meters, sensors, and actuators, then converting it to MQTT/OPC UA for cloud/SCADA integration.
- MQTT for Cloud Connectivity: Lightweight and bandwidth-efficient, MQTT enables the module to upload I/O data (temperature, pressure, status signals) to mainstream cloud platforms (Huawei Cloud, Alibaba Cloud) in real time.
- OPC UA for Enterprise Integration: As the standard for industrial interoperability, OPC UA allows the BA190Pro to seamlessly link with SCADA, MES, and ERP systems, ensuring consistent data flow across enterprise-level workflows.
2. Ethernet-Powered I/O: Flexible, Expandable, Reliable
As an Ethernet I/O module, the
BA190Pro leverages dual 10/100M adaptive Ethernet ports to deliver robust connectivity and scalable I/O capabilities:
- Rich I/O Expansion: With 1-3 I/O slots, it supports flexible combination of Y-series expansion boards—covering DI/DO, relay output, AI/AO, RTD (PT100/PT1000), TC (thermocouple), and pulse counting. Whether you need to monitor temperature via RTD or control equipment via relay output, it adapts to your needs.
- Ethernet Advantages: Wired Ethernet ensures stable data transmission (up to 100m cable length) with low latency, ideal for critical scenarios like building HVAC control or production line monitoring. Cascading support also simplifies large-scale deployment.
- High Precision & Protection: 16-bit AI resolution (±0.1% FSR accuracy) and 2KVrms isolation protection guarantee reliable data acquisition even in electromagnetic interference (EMI) prone environments.
3. Industrial-Grade Durability & Easy Operation
Built for harsh on-site conditions and efficient management:
- Rugged Performance: Operates flawlessly from -40~85℃, with IP30 dust protection and EMC/EMI certification (ESD ±8kV air discharge, EFT 1kV). It stays stable in cold storage, high-heat factories, or humid building basements.
- Plug-and-Play Configuration: Web-based interface enables quick parameter setting and logic programming—no complex coding required. Integrated BLRAT remote access tool supports firmware upgrades and maintenance from anywhere, slashing on-site costs.
Real-World Application: Smart Building HVAC Control
A commercial office building faced challenges integrating Modbus RTU temperature/humidity sensors, an MQTT-based energy management cloud, and an OPC UA-enabled HVAC control system. Traditional I/O modules lacked multi-protocol support, leading to delayed data and manual adjustments.
- The module’s RS485 port collected data from 20+ Modbus sensors (via Modbus RTU) across floors.
- Converted the data to MQTT for real-time upload to the energy cloud, enabling remote monitoring of HVAC energy consumption.
- Linked to the OPC UA-based HVAC control system to automatically adjust air conditioning output based on sensor data.
- Expanded with DI/DO boards to integrate lighting and access control signals, achieving unified building automation.
Result: The building reduced HVAC energy waste by 25%, cut manual maintenance time by 60%, and achieved seamless data flow between sensors, cloud, and control systems.
Why the BA190Pro Stands Out
- Protocol Unification: Modbus/MQTT/OPC UA in one module—no extra converters needed.
- Ethernet Flexibility: Dual Ethernet ports for stable connectivity and cascading, 适配 large-scale deployment.
- I/O Versatility: Expandable to cover analog/digital signals, temperature measurement, and pulse control.
- Industrial Reliability: Wide temperature range and isolation protection for harsh environments.
- Easy Management: Web configuration + remote maintenance, lowering deployment and O&M costs.
For teams tired of protocol chaos and rigid I/O modules, the BA190Pro is the all-in-one solution—turning fragmented automation systems into a connected, efficient ecosystem. Whether for building automation, industrial data acquisition, or energy management, it delivers the flexibility and reliability modern automation demands.
