BL192Pro IIoT EdgeIO Controller

Three Protocols. One Device. Unlimited Possibilities. — MQTT + Modbus TCP + OPC UA in a single edge controller.

One device. Every upstream protocol you will ever need.

Industrial projects change. Requirements evolve. Today you need MQTT for the cloud. Tomorrow you might need OPC UA for IT integration. Next month your customer wants Modbus TCP for their existing SCADA. Buying different controllers for each protocol is expensive. Managing multiple device types is a headache.

The BL192Pro solves this once and for all. It supports all three major uplink protocols — MQTT, Modbus TCP, and OPC UA — in a single device. 

What BL192Pro Does Best

🔄 Three Protocols — One Device

Supports MQTT (for cloud platforms), OPC UA (for IT/OT integration), and Modbus TCP (for traditional PLC and SCADA systems). Enable one, two, or all three simultaneously. Your field data — collected via Modbus RTU/TCP or local I/O — is available through every enabled protocol. No duplicate devices. No data silos.

☁️ MQTT — Direct Cloud Connect

Publish data to Alibaba Cloud, AWS IoT, Huawei Cloud, ThingsBoard, or any standard MQTT broker. Perfect for cloud analytics, remote monitoring, and IoT dashboards.

🔐 OPC UA — Secure IT/OT Integration

X.509 certificates, AES-256 encryption, role‑based policies — compliant with IEC62443. Your IT systems (SCADA, MES, ERP) connect securely via standard OPC UA.

🔌 Modbus TCP — Native PLC and SCADA Access

Your existing Modbus TCP masters — Siemens, Schneider, Delta, Codesys — read data directly. No gateway. No translation layer. Just native Modbus TCP communication.

📦 Expandable I/O — Up to 3 Slots for Y Series Boards

Choose 1, 2, or 3 Y Series I/O boards. Digital, analog, RTD, thermocouple, pulse, serial — all available. Local I/O data is exposed through all three uplink protocols automatically.

🧠 Local Logic Control — Edge Processing Built In

Set up IF-THEN rules, conditional actions, and threshold-based triggers directly through the web browser. Reduce cloud traffic. Reduce PLC workload. Process data at the edge.

🌡️ Built for Harsh Environments — -40°C to +85°C Operation

Wide‑temperature operation, electrical isolation, EMC/EMI protection, independent hardware watchdog. The BL192Pro survives where office equipment fails.

Who Should Use BL192Pro?

🏭 System Integrators with Mixed Requirements

Every customer has different requirements. One wants MQTT to their cloud. Another wants OPC UA to their MES. A third wants Modbus TCP to their existing PLC. Stock one device — BL192Pro. Configure the protocol per project. Simplify your inventory. Reduce your engineering time.

🔧 Projects with Future‑Proofing Requirements

You know you need MQTT today. But next year, the customer might want OPC UA. Instead of replacing hardware, deploy BL192Pro now. Enable MQTT today. Enable OPC UA when needed. Same hardware. Zero disruption.

🏢 Multi‑Protocol Edge Gateways

Your edge gateway needs to serve multiple systems simultaneously — cloud platform for dashboards, MES for production tracking, and local PLC for control. BL192Pro publishes the same field data through MQTT, OPC UA, and Modbus TCP at the same time. One device. Three audiences.

⚙️ OEM Equipment for Multiple End Customers

Your machine is installed in different factories. Each factory has different protocol requirements. Instead of building multiple versions of your machine, standardize on BL192Pro. Configure the uplink protocol per installation. One bill of materials. Endless flexibility.
