ABB A6120 Enclosure Seismic Vibration Monitor Module

Product Brief Introduction The A6120 is a dual-channel enclosure seismic vibration monitoring module for the ABB CSI 6500 machinery health monitoring system, designed for structural and housing vibration measurement.
Tag:

Technical Specifications 2 independent seismic sensor input channels; compatible with electro-dynamic seismic sensors; 0-100 mm/s RMS adjustable measuring range; 3U 1-slot plug-in form factor; API 670 compliant hot-swappable design; operating temperature -20°C to +65°C.

Functional Features Dual-channel seismic vibration measurement; adjustable measurement range; RMS and peak value calculation; sensor fault self-diagnosis; hot swap support.

Application Scenarios Turbine housing vibration monitoring, generator structural vibration measurement, large rotating machinery enclosure seismic monitoring, power plant equipment condition monitoring.

Performance Parameters High measurement linearity; low frequency response capability; stable measurement under harsh conditions; hot swap without system interruption.

Material Composition Metal shielding chassis, precision analog front-end circuit, digital signal processor, gold-plated backplane connector.

Structural Characteristics 3U rack plug-in card structure, front panel status indicators, rear backplane bus interface, sensor input terminals.

Working Principle Acquires low-frequency seismic vibration signals from enclosure-mounted sensors, processes and calculates vibration parameters, transmits measurement data to the system controller via backplane bus for machinery health analysis.

Installation Requirements Insert into CSI 6500 system rack slot; connect seismic sensor cables; configure measurement parameters via system software; verify hot swap function before operation.

Usage Notes Follow API 670 installation standards; calibrate sensor matching during commissioning; avoid strong electromagnetic interference near module.
