Product Description
The ProTech 203 Overspeed Protection System is a digital overspeed trip device
that senses prime mover speed through three magnetic pickups (MPUs). It
consists of three identical, independent, speed-sensing units which continuously
monitor prime mover speed and activate a trip relay when an overspeed
condition is detected. The trip relays of the three units are connected in a twoout-of-three voting configuration so that if any single unit fails, the ProTech
system will still provide the correct output. The units' functions include the ability
to display the actual speed from each speed probe, display the highest speed
signal, on-line testing, and modular design that allows a single failed unit to be
replaced while the device is running. Light emitting diodes (LEDs) and digital
displays on the unit front panel indicate the functional status.
