Native MQTT. Direct Cloud Connect. — Take your field data to the cloud without custom code.
You have sensors, meters, and actuators on the factory floor. They speak Modbus. Your cloud platform — Alibaba Cloud, AWS IoT, Huawei Cloud, or ThingsBoard — speaks MQTT. Getting data from one to the other usually means building custom scripts, running a local broker, or dealing with complex integrations.
The BL192 eliminates all of that. It is a native MQTT controller that collects Modbus data from your field devices and publishes it directly to your MQTT broker.
The BL192 publishes Modbus data directly to MQTT brokers — Alibaba Cloud, Huawei Cloud, AWS IoT, ThingsBoard, or any standard MQTT broker. Your cloud platform receives clean, structured data without custom parsing. No intermediate PC. No additional software.
Choose 1, 2, or 3 Y Series I/O boards. Digital input/output, analog input/output, RTD (PT100/PT1000), thermocouple, pulse counting, pulse output, and serial port modules — all available. Local I/O data is published to MQTT alongside your Modbus device data.
Reduce cloud traffic and latency by processing data at the edge. The BL192 can execute local logic independently — conditional publishing, alarm triggering, threshold-based actions, timer-based control. Set up IF-THEN rules and conditional actions directly through the web browser. No programming software required. Only publish what matters.
Have existing Modbus RTU devices on RS485 — sensors, meters, drives? Connect them to the BL192's isolated RS485 port. The BL192 reads Modbus RTU data and publishes it to MQTT automatically. Your cloud platform sees everything as MQTT messages. No extra gateway. No additional configuration.
Two RJ45 ports with built‑in switch support line topology. Daisy‑chain multiple BL192 controllers or other Ethernet devices without an external switch. Less hardware. Less cabling. Simpler installation.
Wide‑temperature operation from -40°C to +85°C. Electrical isolation, EMC/EMI protection, independent hardware watchdog, and reverse polarity protection. The BL192 survives in outdoor enclosures, remote sites, and unheated facilities. IP30 protection, CE and FCC certified.
Open a browser. Type the IP address. Start configuring. Set up Modbus polling, MQTT broker connection, publish topics, and local logic rules — all through the built‑in web server. No client software. No driver installation. No training required.
Remote firmware upgrades and parameter configuration are built in. Update devices in the field without sending a technician. Perfect for remote and distributed installations.
You are building an IoT solution with Alibaba Cloud, AWS IoT, Huawei Cloud, or ThingsBoard. Your field devices are Modbus‑based — flow meters, pressure sensors, temperature probes, energy meters. The BL192 publishes their data directly to your cloud. No cloud gateway appliance needed. No custom code.
You monitor equipment at multiple remote sites — pumping stations, solar farms, storage tanks, HVAC units. Each site has a few sensors and maybe a local alarm. Running a full PLC and cloud gateway at each site is overkill. Deploy BL192 at each site. It collects local data, publishes to the cloud, and even handles local alarm logic.
Monitor battery status, current, voltage, temperature, and alarms in energy storage systems. The BL192 collects data from Modbus devices, executes local threshold alarms, and publishes everything to your cloud platform. Wide temperature range ensures reliable operation in outdoor or unheated enclosures.
Monitor temperature, humidity, soil moisture, and control fans, pumps, and curtains. The BL192 collects sensor data via Modbus, publishes to your cloud, and executes local control logic without cloud dependency. Perfect for greenhouses, poultry farms, and irrigation systems.
Your customers want remote monitoring of your machines — runtime, fault codes, maintenance alerts. Adding a full PLC and SCADA is too expensive. Add a BL192 to each machine. It collects internal Modbus data and publishes to your cloud platform. You get fleet visibility. Your customers get peace of mind.
