P470EB-1C Johnson Controls Pressure Control

Overview

The Johnson Controls P470EB-1C is a line-voltage electronic pressure control with an integrated display, designed for single-stage, On/Off control across a wide range of HVAC and refrigeration applications. It features a single-pole, double-throw (SPDT) output relay and can be field-set to operate in one of three selectable pressure ranges as either an open-high or open-low control. By utilizing an electronic pressure transducer, it eliminates the physical limitations and leak risks of traditional capillary tubes.

Features

• Three field-selectable pressure ranges up to 750 psi provide broad application flexibility
• Large LCD clearly displays sensed pressure and system status without external gauges
• Lockable three-button front touchpad deters tampering and unauthorized adjustments
• Built-in adjustable anti-short cycle time-delay protects and extends compressor life
• Front-panel LED provides immediate visual verification of the output relay status
• Supports remote transducer wiring up to 100 feet away from the control module
