Inhibit Module

Inhibit Front Panel
Inhibit Front Panel
Inhibit Back Panel
Inhibit Back Panel

  • Inhibits gas flow if external conditions fail to satisfy the specified limits
  • Back panel thermocouple input to monitor temperature
  • Watlow limit controller determines the state of the system by comparing the temperature, pressure, or other customer specified input to the specified limit
  • Alter the limit as needed directly from the controller on the front panel
  • Front panel display of the external reading from the Watlow controller
  • Outputs regarding the state of the system to be read by other modules if desired
  • Integrated hardwired Run/Standby signal
  • Front panel LED status of inhibit, flow, over-temperature, internal errors, enable, and power
