Red Lion Controls PRS1-115V Speed Switch Relay

The Red Lion Controls PRS1-115V Speed Switch Relay is a plug‑in speed switch module designed for 115 VAC operation, intended to drop into compatible Red Lion control bases to provide timed switching in response to a cycling input signal. The PRS1 family also includes variants for 230 VAC supply, but the 115 V version is specified for 115 VAC ±10% and 50/60 Hz systems, making it suitable for common industrial power networks. In operation, the PRS1 monitors successive input cycles and uses internal timing to switch its relay output, a behavior that supports motor-start sequencing and other cycle‑based control tasks in panel environments. The device’s plug‑in form factor facilitates quick installation and replacement, and the official Red Lion product manual details wiring, mounting, and timing concepts for the PRS1 family.
