Emerson EPRO A6500-UM Universal Measurement Card

Product Description

The A6500-UM is a high-performance Universal Measurement Card designed for the Emerson AMS 6500 ATG machinery protection system. This versatile module is engineered to monitor a wide array of critical machinery parameters, including displacement, position, and vibration. With specialized inputs for both eddy current sensors (prox probes) and standard voltage/current signals, the A6500-UM provides the high-frequency response (up to 18,750 Hz) required for precise diagnostics of turbomachinery and rotating assets. It is a core component for facilities moving toward predictive maintenance, offering password-protected configurations and rugged environmental resistance to ensure uninterrupted plant safety.
