Description
The Honeywell RP971A1015 4-port ratio relay is used for controlling the pneumatic signals in HVAC systems with high accuracy. It functions by controlling a downstream pressure to output pressure in accordance to a certain proportion of inlet pressure. It offers versatility in control since it has an input pressure of 5 PSI and an output pressure of 3-13 PSI. The relay is small and has low airflow 0.039 SCFM usage making it ideal for use in different applications. This is the reason for the direct-acting mechanism which guarantees fast and accurate response rates. The following are the benefits associated with this ratio relay; increased system efficiency, increased control accuracy, and decreased energy consumption.
