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.
