Red Lion Controls PRA1-1022 Pulse Rate to Analog Converter Relay

Red Lion Controls PRA1-1022 Pulse Rate to Analog Converter Relay is an obsolete Red Lion module that converts a pulse-rate input into an analog control signal while providing a relay contact for signaling in process control. The unit is designed for 230 VAC operation and mounts in a 12-pin base/socket configuration, a footprint associated with the PRA1 family. Red Lion's literature notes that PRA1 is an older design and is superseded by PRA2 for new installations. Retailers catalog the part as PRA11022, confirming the 230 VAC supply and 12-pin form factor across distributors. The PRA1-1022 is discontinued by the manufacturer, making it primarily suitable for legacy systems that require frequency-to-analog conversion in combination with a relay output. In legacy automation contexts, it translates a pulse or frequency signal from sensors into an analog output for controllers or measurement equipment while offering a discrete relay contact for signaling or interlock purposes.
