EMERSON A6500-UM Universal Measurement Card

The Emerson A6500-UM Universal Measurement Card is a versatile and integral component of the AMS 6500 ATG machinery protection system. It is designed to provide high-performance condition monitoring for critical rotating equipment in industrial settings such as power plants, refineries, and manufacturing facilities. Below are the detailed features and functions of the card:

Key Features:
Sensor Inputs:

Equipped with 2 sensor input channels, which can operate independently or be combined based on the chosen measurement mode.
Compatible with a wide range of sensor types:
Eddy-current sensors
Piezoelectric sensors (accelerometers, velometers)
Seismic (electrodynamic) sensors
Low-frequency (LF) bearing vibration sensors
Hall-effect sensors
Linear Variable Differential Transformers (LVDTs) (when used with the A6500-LC module).

Digital Inputs and Outputs:

Includes 5 digital inputs and 6 digital outputs, which can be configured for various control and alarm functions.
Signal Transmission:

Measured signals are transmitted via the RS485 bus to the A6500-CC Com Card, where they are converted to Modbus RTU and Modbus TCP/IP protocols for communication with host systems or analysis tools.
USB Interface:

A USB socket is provided on the front faceplate for direct connection to a PC or laptop, enabling configuration of the card and real-time visualization of measurement results.

Analog Outputs:

The card features 0/4 - 20 mA analog outputs for signal transmission to external monitoring systems or controllers.
The analog outputs share a common ground and are electrically isolated from the system's power supply to prevent interference.
System Rack Integration:

Operates within the A6500-SR System Rack, which supplies power and manages signal connections for the entire monitoring system.

Measurement Capabilities:
The A6500-UM card offers a comprehensive set of measurement functions for various machinery health indicators:

Shaft Absolute Vibration: Measures the absolute movement of the shaft relative to a fixed point (typically for large rotating machines).
Shaft Relative Vibration: Detects the movement of the shaft relative to its bearings, a key parameter in identifying machinery imbalance or misalignment.
Shaft Eccentricity: Monitors the non-uniformity of shaft rotation, providing critical data to prevent excessive wear or damage.
Case Piezoelectric Vibration: Measures vibration directly from the machinery housing using piezoelectric sensors.
Thrust and Rod Position: Provides data on axial movement or displacement, often used in turbines and reciprocating compressors.
Differential and Case Expansion: Measures differential expansion between different components of a machine, such as turbine casings.
Valve Position: Monitors the position of valves to ensure correct op
