9 To 24 VAC/DC @ 750 ohms Digital Input Signal, 45s, 90s, 1 min, 2 min Input Pulse Range, 0 To 5 VDC Feedback Output Signal, 0 To 20 psig Output Pressure Range, 750 SCIM Exhaust, Exhausts On Power Failure, Includes Gauge.
Features
3 Way Mixing Valve Control, Chiller Loading, Pilot Positioner Control, Pneumatic Valve And Damper Actuator Control, Fan Vane Control, Compressor Staging Applications
The EFP Converts A Floating Point Signal Into A Proportional Pneumatic Signal Ranging From 0-20 psig
The Pneumatic Output Is Proportional To The Signal Input
The EFP Has A Manual Override Switch With Terminal Strip Contacts To Indicate Its Status And A Potentiometer To Vary The Pneumatic Output
Two LEDs Indicate UP Or DOWN Excursions, With An Additional One For Power Indication
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 Size And Pressure Differentials
