Epro MMG1070/02TS MMS Monitoring Module

Product Description

The MMG1070/02TS is a rack-mounted monitoring unit used within Emerson EPRO MMS protection platforms. It processes signals from eddy current proximity probes and converts raw vibration data into evaluated mechanical condition parameters for rotating machinery supervision.

This module is designed for continuous monitoring and protective shutdown logic in high-criticality equipment environments.

System Architecture Integration

The module operates as part of a complete measurement chain:

• Eddy current probe (PR642x series)

• Signal conditioning driver (CON series)

• Rack-based monitoring module (MMG1070/02TS)

It evaluates conditioned signals and executes alarm, warning, and trip logic based on configured thresholds.
