Description

Emerson EPRO A6110 Dual‑Channel Relative Shaft Vibration Monitor Module for AMS 6500 Machinery Protection System

 

Product Details

A6110 is single‑slot plug‑in monitoring module for Emerson AMS 6500 TSI machinery health system, originally manufactured by EPRO (Germany). Origin: Germany. Lifecycle status: EOL discontinued, OEM new production ended; market supply includes NOS surplus and fully‑tested refurbished spare‑parts for power‑plant and petrochemical rotating‑machinery maintenance.

  • Channels: 2 independent relative shaft‑vibration input channels, differential eddy‑current probe input
  • Compatible sensors: PR6422 / PR6423 / PR6424 / PR6425 series eddy‑current probes + CON041 / CON031 proximitor preamplifiers
  • Frequency response: 1 Hz‑2000 Hz, meets API‑670 rotating‑machinery‑protection standard
  • Measurement: shaft radial relative vibration (peak‑peak), also monitors shaft offset/eccentricity
  • Analog outputs: per‑channel 4‑20 mA / 0‑10 VDC proportional output; buffered raw signal output for diagnostic analysis
  • Communication: RS232 / RS485 Modbus‑RTU for configuration and measured‑value readback
  • Relay outputs: 4 independent alarm relays (Alert / Danger / Sensor fault)
  • Power: powered via AMS6500 rack backplane, typical consumption 6 W, max 10 W
  • Hot‑swap support; built‑in sensor cable break / short‑circuit self‑test; password‑protected parameter setup
  • Operating temperature: 0℃ ~ +65℃, storage‑30℃ ~ +50℃, humidity 5‑95 % non‑condensing
  • Weight approx 0.45 kg; 3U single‑slot form‑factor for AMS 6500 chassis

Key Features

  1. Dual‑channel shaft‑relative‑vibration monitor built for AMS 6500 TSI platform, fully compliant with API‑670 machinery‑protection requirements.
  2. Differential eddy‑current input for PR642x probe series; comprehensive sensor fault detection (cable open / short circuit).
  3. Independent high/low alarm and danger relay outputs for machinery trip‑protection logic.
  4. Analog 4‑20 mA / 0‑10 VDC outputs plus buffered raw vibration signal for diagnostic analyzers.
  5. RS485 Modbus‑RTU interface uploads measured values and fault status to plant DCS/SCADA.
  6. Hot‑swappable in‑rack replacement without chassis power‑off; stores start‑up/shutdown transient vibration history data.
  7. Password‑protected configuration prevents unauthorized parameter modification.
  8. Manufactured in Germany; EOL obsolete, only NOS or fully‑tested refurbished spare‑parts available.

 

Main Functions

  1. Receive signals from eddy‑current proximitors, measure shaft radial relative vibration, detect rotor unbalance, misalignment, rub and eccentricity faults.
  2. Compare measured vibration against configurable alarm/danger set‑points, drive relay outputs for alarm or machinery‑trip protection.
  3. Convert vibration values to 4‑20 mA / 0‑10 VDC analog signals for DCS / SCADA system acquisition.
  4. Provide buffered raw vibration output for external spectrum‑analysis and fault‑diagnosis work.
  5. Via Modbus‑RTU upload measurement data, alarm status and fault diagnostics to upper‑level monitoring system.
  6. Capture and store machine start‑up / coast‑down transient vibration waveforms for rotor‑dynamic review.
  7. Perform continuous self‑diagnosis for module hardware and sensor loop faults.
  8. Serve as shaft‑relative‑vibration monitoring unit inside Emerson AMS 6500 TSI protection rack.
