125800-01 Bently Nevada Keyphasor I/O Module

3500/25 Enhanced Keyphasor Module

Description:

• The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module.
• It provides Keyphasor signals to monitor modules in a 3500 rack.
• Converts signals from proximity probes or magnetic pickups into digital Keyphasor signals, indicating when the Keyphasor mark on the shaft aligns with the Keyphasor transducer.
• Supports up to four Keyphasor signals in a normal configuration and up to eight Keyphasor signals in a paired configuration.
