Electronic pressure switch 14

Series EDA Electronic Pressure Controlis an extremely versatile compact package that can replace a separate gauge,two switches, and a transmitter in a system saving money, installation time,and panel space. The EDA incorporates two SPDT relays that have the on and offpoints fully adjustable over the range for control or alarm use. Front facehas LED indicators for switch status and a large backlight two-line displayshowing process value and indication units. Programming is easy with simplemenu structure, two-line display, and external programming buttons.Weatherproof housing is ideal for a wide variety of applications with panelmount, flush mount, or pipe mount ability. Features include zero set,adjustable dampening, menu lock out, peak and valley indication, removableterminal blocks, adjustable time delay, and scalable transmitter output.Service: Compatible liquids andgases.Wetted Materials: 316L SS.Housing: Glass filled plastic.Accuracy: ±1% of F.S. including linearity, hysteresis,and repeatability (indicator and transmitter).Stability: <±2% of F.S. per year.Pressure Limits: Ranges up to 6,000 psi: 1.5 x range;8,000 psi range: 10,000 psi.Temperature Limits: Ambient: 20 to 140°F (-6.6 to 60°C);Process: 0 to 176°F (-18 to 80°C).Compensated Temperature Limits: 32 to 122°F (0 to 50°C).Thermal Effect: ±0.05% of F.S./°F.Display: 4-digit backlit LCD (Digits: 0.60″H x0.33″W).Power Requirements: 12 to 30 VDC/AC.Power Consumption: 2.5 watts.Electrical Connections: Removable terminal blocks withtwo 1/2″ female NPT conduit connections.Enclosure Rating: Meets NEMA 4X (IP65).Warm Up Time: <10 seconds.Mounting Orientation: Any position.Weight: 1.18 lbs (535 g).Agency Approvals: CE and UL pending.

SWITCH SPECIFICATIONS:Switch Type: 2 SPDT relays.Electrical Rating: 5 A @ 120/240VAC, 1 A @ 30 VDC.Repeatability: ±1% of FS (switching only).Set Points: Adjustable 0-100% of FS.Switch Indication: External LED for each relay on thefront panel.Switch Reset: Manual or Automatic.

TRANSMITTER SPECIFICATIONS:Output Signal: 4-20 mA, 1-6 VDC, 1-5 VDC, 0-5 VDC, or0-10 VDC (direct or reverse output selection).Minimum Excitation: 14 VDC.Zero and Span Adjustments: Menu scalable within therange.• 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 onrange).• Test Mode: Simulates input over the range withoutpressuring to easily test switches and transmitter output feature.• Failsafe: For sensor failure, over pressure, hightemperature limit, low temperature limit, or keypad short. User chooses ifrelay is de-energized, energized, or no action. With transmitter option, userchooses an output of 3.6 mA 22 mA, or no action.• Alternation: Selectable alternation of set points between therelays for even wear on duplex pump applications.
