Series-EFP

Floating Point to Pneumatic Output Transducer for 22 to 25 psig Air Supply Pressure

(0)

Converts floating point control to pneumatic output: EFP modules translate floating point input signals into proportional pneumatic pressure for legacy pneumatic control systems.
Selectable pressure ranges: Jumper-selectable outputs support 0-10 psig, 0-15 psig, or 0-20 psig, with adjustable calibration for matching the controlled device.
Ideal for HVAC pneumatic control: Well suited for 3-way mixing valves, chiller loading, pilot positioners, pneumatic valve and damper actuators, fan vane control, and compressor staging.
Flexible input support: Accepts relay contact closure, transistor, or triac signals, making it compatible with a wide range of controllers.
Built-in feedback signal: Provides a 0-5 VDC feedback output proportional to branch line pressure for monitoring and verification.
Manual override for service: Manual/auto switch and potentiometer let technicians vary pneumatic output locally during checkout, setup, or troubleshooting.
Multiple operating models: Choose standard constant-bleed, EFP2 branch-pressure-holding, or EFP2FS fail-safe exhaust models depending on application needs.
Installer-friendly layout: Electrical terminals on one end and pneumatic fittings on the other simplify wiring and tubing in panel-mounted installations.
Reliable panel package: Snaptrack mounting, optional gauge models, LED status indicators, RoHS2/WEEE compliance, and ACI’s two-year warranty support dependable field use.
