EFP | Pulse Width (PWM) Input | Floating Point Input to Pressure Output Interface Module

The EFP converts a floating point signal into a proportional pneumatic signal ranging from 0-20psig. It is designed with electrical terminals on one end and pneumatic connections on the other, allowing for maximum convenience in wiring and tubing installation when panel mounted. The EFP is a constant bleed interface with branch exhaust response time determined by the bleed orifice and pressure differentials. If power fails to the EFP, it will continue to bleed through the bleed orifice until branch pressure is zero psig. The EFP2 incorporates two valves (one controls exhaust) and does not bleed air at set point. Its branch exahust flow and response time are not limited by an internal restrictor and are similar to its load rate. If power fails to the EFP2, branch line pressure remains constant if the branch line does not leak air. The EFP2FS is a two valve fail safe model. It's 3-way branch exhaust valve allows exhaust of branch line air on a power failure. The EFP is covered by ACI's Two (2) Year Limited Warranty.
