An automotive parts manufacturer sought to enhance production line automation by extending its existing PLC system to collect real-time sensor data (temperature, pressure, position signals, etc.) and improve actuator control. Traditional solutions required extensive cabling to the central control cabinet, increasing costs and maintenance complexity.
The BL190 Modbus TCP Edge I/O Module was deployed as a remote I/O extension for the PLC, creating a distributed I/O system:
Stamping Station: BL190+Y13 (8DI dry contact) + Y24 (4DO relay) Monitor mold position sensors / control hydraulic valves
Welding Station: BL190+Y31 (4AI 4-20mA) + Y21 (8DO PNP) Collect welding current / control welding guns
Assembly Station: BL190+Y01 (4DI+4DO mixed) + Y51 (2RTD) Detect workpiece presence / monitor bearing
The BL190 proved to be a reliable, cost-effective solution for PLC I/O expansion in smart factories. Its Modbus TCP compatibility, flexible I/O options, and industrial-grade durability make it ideal for distributed automation systems.
