3-Range Electronic Pressure Control w/ Display

The P470 Electronic Pressure Control with Display is a single-stage, On/Off, electronic pressure control with an SPDT (Single-Pole Double-Throw) output relay. The control may be field set to operate in one of three pressure ranges (0 to 100 psi, 0 to 500 psi, or 50 to 750 psi), as either an open-high or open-low control.

The P470 control features a large LCD that displays the sensed pressure and other system-status indicators, as well as the adjustable setpoints in the programming mode. The P470 control has a lockable, 3-button touchpad for adjusting setpoints, and a front-panel LED (Light-Emitting Diode) that indicates the output relay status.

The P470 control uses a P399 Electronic Pressure Transducer to generate a pressure signal and WHA-P399 Wiring Harness, which eliminates many of the constraints of capillary-tube control applications.

Features

• Easy to Read Liquid Crystal Display (LCD): Clearly displays the sensed pressure (and other control information), and in many situations pressure may be monitored without applying gauges to the controlled equipment
• Three Field-Selectable Pressure Ranges Between 0-750 psi: Provides the flexibility to cover most HVAC/R pressure applications with three fieldselectable pressure ranges; 0-100 psi with 5 psi minimum differential, and 0-500 psi or 50-750 psi with 20 psi minimum differential
• 24 VAC, and 120 or 208/240 VAC Models: Increases application options, with two controls that cover most common voltages
• Lockable, 3-Button, Front-Panel Touchpad: Deters tampering and over adjustment of control settings by unauthorized personnel
• Built-in, Adjustable, Anti-Short Cycle Time-Delay: Reduces compressor short cycling and nuisance lockouts, which can extend compressor life
• Uses an Economical and Versatile Transducer and Wiring Harness: Eliminates many of the constraints of capillary control applications and allows up to a 100 ft (30.5m) cable between control and transducer
