Description
Unlike previous systems, the Orbit 60 Series system supports
Keyphasor configurations for any dynamic input channel
through the PAV, PAS, PAA, PAD, and PVT input modules. For
high-phase accuracy applications (over 12,000 rpm) theKeyphasor Input Module must be used. The input speed limit
is 120,000 rpm and can accept input speed signals up to
1,200,000 cpm (20 kHz). Each Keyphasor Input Module canaccept up to four speed inputs. Input configurations to thismodule can also support Acceleration, Differential Expansion,Radial Vibration, and Thrust inputs. The Keyphasor input
Module occupies a single slot.
Although the system allows the user to configure
channels on the Keyphasor Input Module to serve
as non-speed input types as described above,
there will be a decrease in accuracy on thesemeasurements when compared to PAV, PAS, PAA,
PAD, and PVT modules. These non-speed inputs
also cannot be utilized in SIL applications. TheKeyphasor Input Module can only be utilized in SIL
applications when configured for speed inputs.
Any channel on the module can be configured as a onceper-turn Keyphasor or a multiple-event-per-turn speed
signal from a rotating shaft or gear used to provide aprecision timing measurement. The Keyphasor Input Module
works with the following transducers:lllMagnetic pickup
3-wire Prox
3-wire Accel

The module senses the Keyphasor signal when the sensor
reads a notch or protrusion in the target, then digitizes andprocesses the signal to provide machine rotative speed andORBIT 60 SERIES Keyphasor Input ModuleDatasheet

the phase reference for vector parameters,such as 1X amplitude and phase. The
Keyphasor gives phase reference informationfor vibration measurements, providing key
relationships for diagnostic analysis. It also
provides speed/phase reference for thesynchronously sampled waveforms capturedby the Condition Monitoring Module.
The 2-wire input connection provides agalvanically isolated, hi-impedance input
which primarily supports magnetic pick-up
speed sensors. The isolated input eliminates
potential ground loops that can occur when
speed sensors are shared between thevibration system and other instrumentation.
The Keyphasor Input Module provides abuffered transducer output for each channel.
Within Orbit Studio software, each output canbe configured within Orbit Studio Software to beeither a true analog signal representative of theinput or a conditioned/processed digital TTL
signal replicating machine speed andmaintaining phase with the input signal.
The module OK LED indicates when the module
is functioning properly, and the LINK LED
indicates when the module is communicating
to the rest of the system. Four Channel StatusLEDs located on the utility side of the module
indicate a connected sensor is installed and in
OK condition.

2 These sensors can be configured using a Custom transducer configuration.
3 PVT modules are recommended for new sensor installations only. Projects using the Velomitor CT or retrofits that reuse

existing sensors should use PAV or verify sensor power limits.

The PVT is only for positively biased sensors.
The Velomitors® and IEPE sensors can be configured on the PAV as a custom transducer.
