Product Overview

The PRS10101 is a plug-in Speed Switch versatile reliable and economical solution to most machine speed switching problems. It is not affected by over speeding and will operate in either direction of rotation. The heart of the PRS1 is a solid-state CMOS logic circuit, that continuously measures the elapsed time between successive trailing edges (negative going) of an incoming pulse train or waveform. It compares this time with an adjustable set-point reference and determines if the period of the waveform is longer or shorter than the set-point reference. The internal relay is energized during "normal" operation and can be set to de-energize on either under or over-speed by a programming switch. The unit can be connected for simple over or under-speed detection or for latch/trip-OFF operation in a machine STOP/START circuit. It features built-in hysteresis of 5% of set-point speed. This prevents the output relay from chattering when operating at or near the set-point speed.
  • Over-speed, under-speed or zero-speed detection
  • 1/2% Maximum repeatability
  • LED relay ON indicator
  • Programmable input circuit accepts outputs from a variety of sensors
