PRODUCT INFORMATION
Product Overview
The Bently Nevada 3500/25 3500 Keyphasor Module provides shaft timing reference signals for 3500 machinery protection systems. This half-height module contains two independent channels. It accepts input signals directly from proximity probes or magnetic pickups. The unit converts these transducer inputs into digital Keyphasor signals for system operation. Each signal delivers shaft timing reference at the Keyphasor mark.
A normal 3500 rack installation supports up to four Keyphasor signals across installed modules. Paired rack configurations can support up to eight Keyphasor signals. For Triple Modular Redundant architectures, two modules operate in parallel. This design delivers shaft timing pulses across designated monitoring channels.
