Emerson EPRO A9360/08-09-00 Rack Interface Module

Product Description

The A9360/08-09-00 (often part of the Emerson CSI 9360 series) is a versatile, high-precision industrial control module designed for machinery protection and condition monitoring. While often categorized as a "Modbus and Rack Interface Module," it primarily functions as a Vibration/Position Transmitter that integrates with Eddy Current Sensors (such as the PR6423 series). It converts raw sensor signals into industry-standard 4-20 mA outputs and digital Modbus data, making it ideal for monitoring shaft displacement, vibration, and expansion in turbines, compressors, and other critical turbomachinery.
