Product Details
Manufacturer: Bently Nevada
Series: 3500/25
Model/Part Number: 3500/25-02-03-RU
Model Type: Internal Barrier I/O Module
Description
The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module designed to provide Keyphasor signals to the monitor modules in a 3500 rack. The module receives input signals from proximity probes or magnetic pickups and converts them into digital Keyphasor signals that identify the exact position of the Keyphasor mark on the rotating shaft. The 3500 Machinery Protection System can handle up to four Keyphasor signals in a normal configuration, or up to eight signals in a paired configuration.
Specifications
Inputs
- Power Consumption: 3.2 Watts (typical)
-
Signal:
- Each Keyphasor Module can accept up to two transducer signals from proximity probe transducers or magnetic pickups.
-
Input Signal Range:
- Non-Isolated I/O Modules: +0.8V to -21.0V
