- Two isolated measurement channels support independent case seismic vibration protection
- A one-slot hot-swappable card integrates with the AMS 6500 machinery protection rack
- Configurable signal conditioning, alarms, relays, and diagnostics support critical rotating assets
Emerson A6120 converts velocity-sensor signals into monitored vibration values for two independent machinery channels.
The module combines signal conditioning, limit comparison, alarm logic, analog outputs, and self-diagnostics within the AMS 6500 protection architecture.
Confirm the rack, sensor circuits, channel configuration, relay behavior, address, software record, and maintenance bypass procedure before returning protection to service.
Availability, condition, price, and shipping time for A6120 are confirmed during quotation.

- The input-frequency lower cutoff is selectable as 1 Hz or 5 Hz, while the upper cutoff is adjustable from 50 Hz to 2000 Hz
- Lifting-coil current is configurable from 0...8 mA in 40 µA steps
- The buffered sensor supply is galvanically separated from system voltages and protected against open and short circuits
- Alert and danger setpoints are adjustable from 5...100% of full scale with 1% resolution
- Alarm hysteresis on a decreasing signal is adjustable from 0...20% of full scale
- Alert and danger functions can be configured as normally open or normally closed and can be blocked when the channel is not OK
- Self-monitoring covers power, sensor, cable, module electronics, and watchdog status
- Overload and module-temperature conditions are included in diagnostic monitoring
- Front buffered and rear analog outputs support commissioning and fault isolation
- Protect steam, gas, and hydro turbines using case seismic vibration measurements
- Monitor compressors and other critical rotating machines with compatible velocity sensors
- Use the two independent channels in an AMS 6500 rack after validating alarm and relay configuration
