  • Provides mass flow control of one gas and a fail-safe purge system with orifice controlled purge rate

  • Flow rates up to 2500 SLPM per gas

  • All-digital control eliminates analog calibration requirements and inaccuracies

  • Ethernet Interface for simple configuration and expansion!

  • The output from multiple Gas Delivery Modules may be combined to provide dynamically controlled gas flow rates and compositions, including Stoichiometric control

  • System-wide control of all Fideris® Test System Components using FCPower Software, Labview, or other programming language

  • Integrated hardwired Run/Standby signal

  • Power Over Ethernet (PoE) for redundant power

  • Front panel LED status of Ethernet communications, inlet gas pressure, gas enabled, and power

  • Pressure regulator on inlet gas line to provide the highest degree of accuracy, and check valves for gas backflow prevention
