Emerson EPRO A6370D Overspeed Protection Monitor

EPRO A6370D Overspeed Protection Monitor

Description

The A6370D 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 (A6370D)
and one backplane (A6371D).
The system is designed for use with Eddy-Current sensors, Hall- Element sensors and
Magnetic (VR) Sensors.
