Inputs

Signal Input: 2 independent differential channels for piezoelectric sensors, supporting piezoelectric accelerometers and velometers.

Input voltage range

A6125/00: 311 ~ 9500 mV peak-to-peak

A6125/10: 16 ~ 450 mV peak-to-peak (variant for high-temperature sensors)

Input impedance: Greater than 100 kΩ

Sensor excitation: 2–8 mA constant current, 30 VDC

Frequency bands

Accelerometer mode: Low 6–1000 Hz / Medium 10–2000 Hz / High 30–8000 Hz

Velometer mode: Low 2–250 Hz / Medium 6–1500 Hz / High 10–2000 Hz

Outputs

Buffered dynamic vibration signal outputs available on front and rear terminals.

Per-channel analog proportional outputs

0/4–20 mA current output with maximum load less than 500 Ω

0–10 VDC voltage output with minimum load greater than 100 kΩ

Alarm relay outputs corresponding to Alert and Danger trip thresholds

Backplane digital communication interface for data exchange within the AMS 6500 rack

The Emerson A6125 is a dual-channel piezoelectric casing vibration monitor module deployed in the AMS 6500 machinery protection system and conforms to the API 670 standard.

Signal Acquisition and Conditioning

It receives differential signals from piezoelectric accelerometers and velometers while providing constant current excitation to sensors. Selectable frequency bands for accelerometer and velometer modes are available for vibration signal filtering.

Real-time Casing Vibration Measurement

The module continuously measures absolute vibration on bearing housings of rotating machinery and computes vibration amplitude to evaluate equipment operating conditions.

Threshold Monitoring and Alarm Control

Configurable Alert and Danger threshold levels are supported. Adjustable alarm delay and hysteresis functions avoid false alarms. Relay outputs will be triggered when vibration values exceed preset limits to execute machinery protection logic.

Multi-form Signal Output

Buffered dynamic vibration signals are accessible from both front and rear terminals. It transmits proportional analog signals including 0/4–20 mA current and 0–10 VDC voltage for interfacing with DCS, SCADA and display units.

Module Self-Diagnosis

It autonomously identifies sensor failures, cable open circuits, abnormal module temperature and hardware errors, and generates corresponding fault alarms.

System Data Communication

Measured data, alarm states and configuration parameters are transmitted via the backplane bus to the AMS 6500 rack to enable centralized monitoring and parameter configuration.

Hot-swappable Function

Modules can be replaced online without powering down the whole monitoring rack, enhancing system maintainability.

Predictive Maintenance Enablement

Vibration data can be forwarded to AMS Suite to facilitate trend observation, spectrum analysis, and early detection of failures such as rolling bearing damage and gearbox mechanical abnormalities.
