EMERSON A6370D/DP Overspeed Protection Monitor

A6370 Overspeed Protection Monitor

The A6370 Monitor is part of the AMS 6300 SIS Overspeed protection system and is

mounted in a 19” rack (84HP width and 3RU height) in combination with the A6371

system backplane. One AMS 6300 SIS consists of three Protection monitors (A6370)

and one backplane (A6371).

The system is designed for use with Eddy-Current sensors, Hall- Element sensors and

Magnetic (VR) Sensors
