Model TSCU-R -Tunnel Sensors Control Unit Rugged Version
The TSCU-R is a central control unit designed for operation with compatible Tunnel Sensors instruments including the VICONOX, AIRFLOW-MkII and CROSSFLOW within the tunnel environment. The TSCU-R is a central control unit designed to be mounted in the tunnel bore but at a level and location that is more accessible than most monitor installations high up on the tunnel wall. The TSCU-R’s on board USB socket enables a laptop computer with Tunnel Sensors utility software to communicate with the monitors.
The TSCU-R can connect with up to eight monitors on a common RS485 communication bus, gathering all available readings in real time using a single daisy chain cable connection. It can then present the data to the tunnel SCADA or ventilation control system using a range of onboard interfaces including Digital Relays, Current Outputs and Modbus RTU serial communication.
With an enclosure made from stainless steel that provides IP67 rated ingress protection, the TSCU-R is a dedicated communication hub designed for harsh tunnel environments.
