Input/Output (I/O) Modules

Every module (Monitor, Keyphasor, Power Supply, Communication Processor, etc.) requires a corresponding I/O module. Main modules connect to the backplane inside the rack,3500/90 125728-01and I/O modules connect with the other side of the backplane, behind their associated main modules. For bulkhead-mounted racks, only,3500/90 125728-01each I/O module connects to the face of the backplane above its associated main module.

Keyphasor Module

The 3500/25 is a halfheight module that provides power and termination for up to two Keyphasor transducers. When applications require one or two Keyphasor transducers, simply install a single3500/90 125728-01module. The 3500 System can accommodate up to four Keyphasor transducers per rack by installing two3500/90 125728-01Keyphasor modules in the rack. When two 3500/25 Keyphasor modules are used, they must be installed in the same rack slot,3500/90 125728-01one above the other. Keyphasor signals from the 3500/25 module(s) can be routed to appropriate monitor modules via the 3500’s rack backplane for use in speed, phase, tracking filter, and other measurements
