Bently Nevada ORBIT 60 SERIES Dynamic Input Modules Connectors

Negative Transducer Input Modules

The following cards work with negative-voltage external sensors offering four variants:

• PAV Negative Dynamic Sampler (Prox, Accel, Velom)

• PAS Negative Dynamic Sampler (Prox, Accel, Seismic)

• PAA Negative Dynamic Sampler (Prox, Accel, Aero)

• PAD Negative Dynamic Sampler (Prox, Accel, DC LVDT)

• KPH High Speed Keyphasor (Prox, Accel, Magnetic Pickup)

Positive Transducer Input Module

The Positive Voltage Transducer (PVT) input module interfaces with industry-standard

third-party IEPE sensors, as well as sensors that use a 3-wire (power, common, signal)

or a custom 2-wire (A/+ and B/-) positive-voltage interface.

The PVT is the preferred module to use for IEPE sensors, including the Bently Nevada

Velomitor (3005xx) and IEPE accelerometers. Using the PVT modules for

these sensors improves noise performance of the sensor.

• PVT Positive Dynamic Sampler (Prox, Accel, Velom)

The PVT module is recommended for new Velomitor installations only.

Projects using the 190501 Velomitor CT or retrofits that reuse other existing 

Velomitor sensors should use the PAV module unless the user can verify the

sensor power limits are appropriate for existing Velomitors.

Connectors

The Dynamic Input module uses an ix Industrial connection to provide access to

four buffered transducer output (BTO) connectors for each of the dynamic channels, with short circuit protection.

The ix Industrial connection is available on the public and utility side of the module.
