Red Lion Controls PRS11021 Relay Module

The Red Lion Controls PRS11021 Relay Module is a 115 VAC, 50/60 Hz accessory designed for use with Red Lion’s PRS Speed Switch family, mounting in a 12-pin base for a compact plug-in interface. This module provides a relay output that is controlled by the PRS Speed Switch to switch external loads in motor-speed monitoring applications, enabling integration with drives, conveyors, and other rotating equipment within an automation system. As part of the PRS lineup, the relay module supports Red Lion’s approach to monitoring and controlling motor speed in industrial environments. Common applications include motor speed control, line automation, and process interlocks in manufacturing settings. The 12-pin base and 115 VAC, 50/60 Hz rating define its electrical footprint and compatibility within the PRS modular controller ecosystem.
