3500/25 125792-01 Bently Nevada Output buffered keyphasor

Description

A system with more than four Keyphasor inputs may use a
paired configuration provided there are no more than four

primary Keyphasor input signals. A paired
configuration requires two consecutive
monitoring positions in either the upper/lower
or both half-slot positions. Four Keyphasor
modules will accept four primary and four
backup input channels and provide four output
channels (one per module). A configuration of
two paired and one non-paired (three
Keyphasor modules total) is also possible. In
such a configuration, the user may configure
the one non-paired Keyphasor (order either
two 2-channel or one 1-channel and one 2-
channel option)
The Isolated Keyphasor I/O module is designed
for applications where 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.
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 multievent-per-turn inputs, field-upgradeable
firmware, and asset management data
reporting.
