Epro 9100-00049-03 Vibration Monitoring Module

Overview

The 9100-00049-03 is a rack-based processing module developed for Emerson EPRO machine protection platforms. It evaluates input signals from eddy current measurement chains and converts them into actionable vibration and displacement data used for equipment protection and diagnostics.

It is typically deployed in MMS 3000 and MMS 6000 systems where continuous supervision of critical rotating assets is required.

Functional Role in Measurement Chain

Within a complete monitoring loop, the 9100-00049-03 operates downstream of signal conditioning hardware:

• Eddy current probe (PR642x series)

• Signal driver module (CON series)

• Monitoring and protection module (9100-00049-03)

The module processes incoming analog signals and applies configured logic to generate alarms, trips, and system outputs.

Frequently Asked Questions

Q1: Does this module connect directly to proximity probes?
No. It requires a CON-series signal driver between the probe and the module.

Q2: Can it initiate machine shutdown?
Yes. It provides relay outputs for alarm and trip functions based on configured thresholds.

Q3: Is it compatible with all MMS systems?
It is designed specifically for MMS 3000 and MMS 6000 platforms.

Q4: What kind of faults can it detect?
It can identify probe failure, cable disconnection, and abnormal signal conditions within the measurement chain.
