The Edwards TIC turbo pump controller is a compact turbo controller with a large clear graphical display, an intuitive user interface, and serial communications providing full remote control and data logging functions via a new Windows based PC program. The controller automatically recognizes and supports one 24 VDC turbomolecular pump from the EXT and nEXT turbo pump range. The Edwards TIC controller provides output power to directly support the turbo cooling fan & vent valve along with mains for the backing pumps (up to the nXDS20i dry scroll and RV12 rotary vane vacuum pumps) which may be controlled via an optional relay box. There are two different output power variants available, 100 or 200 Watt which determines the ramp speed of the turbo pump. In addition, the 200 Watt models have the ability to power a 24 VDC backing pump, such as Edwards XDD1 or nXDS through a 15 pin D-sub connector. These Edwards TIC turbo pump controllers are designed to operated EXT 75dx, nEXT 240, 300 and 400 turbo pumps, have Edwards part number D397-12-000, but do not include pressure gauge control function support (no instrument control). Other part numbers of the Edwards TIC turbo pump controllers can operate the turbo pump and instruments which adds the ability to control up to 3 of the Edwards range of active vacuum pressure gauges (excluding the IGC & Barocels models).
