Product Introduction
Emerson A6370D is a high-performance overspeed protection monitor, which is part of the Emerson AMS 6300 SIS overspeed protection system. It is mainly used to monitor the speed of rotating machinery (such as turbines, compressors, etc.). Once the speed exceeds the set value, an alarm signal will be issued and corresponding protective measures will be taken to prevent equipment damage.

Product Details
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.
