DX/nEXT Pump Profibus Communications Module
Manufacturers, laboratories and research establishments are converting to fieldbus to take advantage of the reduced cabling and network equipment costs.
Edwards offers a compact, Din rail mountable module to allow Profibus protocol communications with the TIC Turbo and Instrument Controllers, or directly with Edwards DX turbo pumps.
The TIC is a versatile, advanced system controller capable of controlling a series of vacuum pumps and up to three Edwards Active vacuum gauges. The addition of the Profibus module allows full advantage to be taken of digital multi-drop communications.
The new Profibus module has been designed to fit alongside the TIC, making installation very simple.
The new module carries full Profibus International accreditation. This stringent independent test process gives a high level of confidence in the reliability of the new unit, and its compatibility and functionality with all Profibus instruments and networks.
