Native Modbus TCP. Expandable I/O. Local Logic. — One device that connects your field devices to your Modbus network.
You have a Modbus TCP network. Your PLC or SCADA speaks Modbus TCP. But your field devices — sensors, meters, actuators — are scattered across the factory floor. Running individual cables back to the PLC is expensive. Adding more I/O boards is inflexible. And handling simple tasks still burdens your main PLC.
The BL190 solves all of this. It is a native Modbus TCP controller that sits where your devices are — collecting data, controlling outputs, and even executing local logic — all while appearing as a standard Modbus TCP slave to your PLC or SCADA.
Think of it as your Modbus network's remote I/O station with built‑in intelligence.
The BL190 communicates using standard Modbus TCP protocol. Your PLC or SCADA sees it as a standard Modbus slave. Supports up to 15 simultaneous Modbus TCP clients.
Choose 1, 2, or 3 Y Series I/O boards based on your needs. Digital input/output, analog input/output, RTD (PT100/PT1000), thermocouple, pulse counting, pulse output, and serial port modules — all available. Mix and match. Start small. Scale when needed.
Why burden your main PLC with simple tasks? The BL190 can execute local logic independently — conveyor start/stop, material detection, timer‑based actions, alarm triggering, conditional control. Set up IF-THEN rules, register operations, and conditional actions directly through the web browser. No programming software required. No additional cost.
Have existing Modbus RTU devices on RS485 — sensors, meters, drives? Connect them to the BL190's isolated RS485 port. The BL190 converts Modbus RTU to Modbus TCP automatically. Your PLC reads them as if they were native TCP devices. No extra gateway. No additional configuration.
Two RJ45 ports with built‑in switch support line topology. Daisy‑chain multiple BL190 controllers or other Ethernet devices without an external switch. Less hardware. Less cabling. Lower cost. Ideal for distributed machine layouts and long production lines.
Designed for the real factory floor. Wide‑temperature operation from -40°C to +85°C. Electrical isolation, EMC/EMI protection, independent hardware watchdog, and reverse polarity protection. The BL190 survives where office‑grade equipment fails. IP30 protection, CE and FCC certified.
Open a browser. Type the IP address. Start configuring. Set up I/O parameters, define logic rules, monitor real‑time data — 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. Reduce downtime. Lower service costs.
Your control system is built around a Modbus TCP master — Siemens, Schneider Electric, Delta, Codesys, or any other Modbus TCP PLC. You need to add distributed I/O points without changing your programming environment. The BL190 appears as standard Modbus addresses. Your existing code works. Just add the controller to your network.
An existing production line uses Modbus but needs more I/O points. The BL190 drops in seamlessly. No protocol changes. No controller reconfiguration. Just more I/O where you need it, with local logic to offload simple tasks from the main PLC.
Your SCADA or HMI reads Modbus TCP directly. You want to bring field sensor data into the visualization without going through the PLC — or in addition to it. The BL190 gives your SCADA direct read/write access to I/O points over standard Modbus TCP.
Your machine uses Modbus TCP for control and monitoring. You need a flexible, cost‑effective I/O expansion system that speaks the same language as your main controller. The BL190 is the expansion partner you have been looking for — native Modbus, local logic, and expandable I/O.
Monitor power meters, battery status, current, voltage, and temperature in energy storage systems or remote facilities. The BL190 collects data from RS485 Modbus devices, executes local alarms, and reports everything back via Modbus TCP. Wide temperature range ensures reliable operation in outdoor or unheated enclosures.
