Dwyer Series EDA Electronic Pressure Controller

Features & Benefits

  • Display Units: psi, kg/cm², bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in² (choices depend on range).
  • Test Mode: Simulates input over the range without pressuring to easily test switches and transmitter output feature.
  • Failsafe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.
  • Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.
