Quest Controls - Model RSC 1000 -Remote Site Controller for Critical Infrastructure

The RSC 1000™ Site Controller with IP connectivity is specifically designed for use in all remote facilities. It provides control & monitoring of the site’s AC Units, Power Meters, Generators, Fuel Cells, Solar Panels and Fuel Tanks. The RSC 1000 includes a touch screen display and direct support for Modbus communication to any compatible device. In a single-box solution, users can maximize their visibility and control into their facility.

Quest has boldly reimagined the control and monitoring experience of remote CI structures using touch screen technology. Operators can manage the Site Controller using custom graphics created for users of varying expertise. The high resolution display makes the RSC 1000 easy to use by the local technician to monitor and control the site’s HVAC units and manage peripheral systems connected via Modbus RTU. The

RSC 1000 allows the end-user to improve quality, reduce maintenance costs, shrink energy consumption and boost productivity through intelligent remote management of the facility. The RSC 1000 Controller is specifically designed for use in remote sites offering added value of the latest in facility automation. Expand RSC 1000 to support up to four HVAC units with the RSC-ACX.
