Product Overview
The Bently Nevada 3500/25 Keyphasor I/O Module is a critical component designed to provide essential timing information for the 3500 rack. Model 125800-01 is a two-channel, half-height unit that accepts input signals from proximity probes or magnetic pickups. It converts these signals into a digital Keyphasor signal, which indicates the precise timing of a rotating shaft's once-per-turn event. This functionality is vital for measuring shaft rotative speed and vibration vector parameters.
Part of an enhanced product line, the 3500/25 offers expanded signal processing capabilities while maintaining full compatibility with legacy systems. The 125800-01 also features buffered Keyphasor outputs available on both the front and rear of the rack, providing flexibility for a variety of industrial applications. Its robust design ensures reliable performance in demanding environments.
