Rex Revolutions here, with a compact little control module that knows exactly what job it came to do. 

The Red Lion Controls PRS1-1011 is a plug-in speed switch designed for machine speed monitoring applications where dependable signal response and straightforward adjustment matter. 

Built for 115VAC operation and a 10–100Hz input range, it gives buyers a purpose-built control solution for monitoring rotating equipment, conveyor systems, process machinery, and other installations where speed needs to be watched and acted on. 

This PRS1-1011 module uses a 12-pin plug-in format that makes it a practical fit for panel service, replacement stock, and legacy machine support. A Form C SPDT relay output, LED relay-on indicator, built-in +12VDC regulated sensor power, and 20-turn setpoint adjustment give it the kind of real industrial functionality that makes Red Lion controls popular in maintenance inventories and machine-control cabinets. 

It is a compact, application-specific module meant to deliver clean speed-switching performance without wasting panel space or setup time. For buyers maintaining older equipment, supporting established control systems, or stocking proven industrial components, this is the kind of module that stays useful because it was built to do one job well. 

The PRS1 family’s blend of adjustable speed monitoring, plug-in convenience, and durable industrial design makes the PRS1-1011 a smart fit for control cabinets where reliable response and easy replacement matter.
