EMERSON A6370D 9199-00040
- Product Name
Emerson EPRO A6370D Overspeed Protection Monitor
- Product Description
The Emerson EPRO A6370D is a key component of the AMS 6300 SIS overspeed protection system. It is specifically designed to reliably protect industrial machinery by continuously monitoring rotational speed and promptly triggering safety measures once overspeed occurs. This module is engineered to be mounted in a 19-inch rack with 84 HP width and 3 RU height, working in conjunction with the A6371 system backplane. A complete AMS 6300 SIS is composed of three A6370 protection monitors and one A6371 backplane.
It supports a variety of sensors such as eddy current, Hall element, and magnetic (VR) sensors, and is equipped with multiple communication interfaces including USB, RS – 485, and Profibus DP. These features enable seamless integration with various industrial control systems. It is widely used in turbines of chemical plants, pumps on oil platforms, and test engines in the aerospace field to ensure operational safety and prevent equipment damage caused by excessive speed.3.
