Functional highlights

Dual-channel flexibility allows radial, axial or tangential vibration measurement on a single shaft section
Remote limit multiplier and trip bypass via Modbus or AMS Suite
High immunity to EMI through galvanic isolation of sensor supply and system power
Compact 3U footprint halves cabinet space versus legacy 6U four-channel cards

Applications

Steam turbines, gas turbines, compressors, hydro turbines for continuous shaft vibration monitoring and protection
Predictive maintenance programs using AMS software for early fault detection and scheduling of repairs
Safety shutdown systems where vibration relays (A6740) initiate alarms or trips to safeguard machinery
