P70DA-400C Johnson Controls Pressure Control

Overview

The Johnson Controls P70DA-400C is a high-pressure cutout control designed for commercial refrigeration and air conditioning systems. It utilizes a Single-Pole Single-Throw (SPST) open-high switch action to protect system components from excessive high-side pressure by cycling off equipment when limits are exceeded.
