The 135473-01 Keyphasor I/O Module features internal barriers and terminations, offering a complete Keyphasor signal solution. The  135473-01 3500/25 Isolated Keyphasor I/O module is designed for applications in which the Keyphasor signals are tied in parallel to multiple devices and require isolation from other systems, such as a control system. The Isolated I/O module was created specifically for Magnetic Pickup applications but is compatible with and will provide isolation for Proximitor* applications as long as an external power supply is provided. Note that the intent of this I/O module was primarily to measure shaft speed and not phase. The module can provide phase measurements, but this I/O introduces a slightly higher phase shift than the Non-Isolated I/O version. Figure 1 shows the amount of phase shift that the Isolated I/O modules will add at different machine speeds. Enhanced product features include generation of once-per-turn event signals from multi-event-per-turn inputs, field-upgradeable firmware, and asset management data reporting.
