KSC Series

The Kruger KSC Series Smart Data Acquisition Card is designed for tunnel fans, providing a digital solution to gather all fan sensor data and transmit it directly to the PLC via Modbus TCP over LAN. By replacing bulky analog wiring with a single LAN connection, it reduces installation costs, eliminates signal loss, and enables faster setup with true plug-and-play convenience. The system integrates data analytics, vibration analysis, and motor heater control, allowing preventive and predictive maintenance for a more reliable and efficient tunnel ventilation system. Each fan is assigned a unique IP address, ensuring smooth communication and seamless integration with modern tunnel systems such as sensors, cameras, and SCADA platforms.
