7716 Hydrogen Ignition Module

The 7716 Hydrogen Ignition system was designed as a replacement for the 7616 Hydrogen Burnoff. Updates include up-to-date electronics package with a solid state relay design for longer fault free operation and replacement of the heater coil ignition system with a silicon carbide heater design.

Product Specifications:

• (2) 450 watt Silicon Carbide heaters
  
• (2) CAL3300 temperature readouts to verify 760°C obtained
  
• Warning alarm for failure of one SiC heater
  
• Lock-out alarm for failure of both SiC heaters
  
• Programmable heater ON circuit via function output
  
• 60 Second time delay to allow temperature to reach >760°C prior to enabling alarm monitor circuit.

VCVD Gas Electronics Module

Engineered for additional functionality, with a focus on improved In-situ diagnostics and ease of use, the VCVD Interface IIITM provides a three-fold increase in electrical accuracy in the leak rate measurement circuit. Combine this with an LCD readout, self-diagnostic capabilities and additional status monitoring LEDs, the VCVD Interface IIITM takes a major leap forward in VCVD processing.
