SPECIFICATIONS
Part Number: 126648-01
Manufacturer: Bently Nevada
Series: 3500
Product Type: Keyphasor I/O Module (External Terminations)
Availability: In Stock
Country of Manufacture: United States (USA)
126648-01 is a Keyphasor I/O Module (External Terminations) developed by Bently Nevada. The Isolated Keyphasor I/O module is intended for use in situations where many devices are connected to Keyphasor signals simultaneously and where isolation from other systems, such as a control system, is necessary. The Isolated I/O module is compatible with and will offer isolation for Proximitor applications as long as an external power supply is available. It was designed specifically for Magnetic Pickup applications.
126648-01 Features
- The Enhanced Keyphasor Module is an enhanced 3500 system module. It improves on the previous design's Keyphasor signal processing capabilities while maintaining total downward compatibility in terms of shape, fit, and function with current Keyphasor modules for usage in older systems.
- The Keyphasor module, PWA 125792-01, has been totally replaced with the more current 149369-01 module. When a system Keyphasor input is required for Triple Modular Redundant (TMR) applications, the 3500 system should use two Keyphasor modules. In this design, the modules function simultaneously to deliver both a primary and secondary Keyphasor signal to the other modules in the rack.
- A system with more than four Keyphasor inputs may use a paired arrangement as long as there are no more than four major Keyphasor input signals. A paired design necessitates two consecutive monitoring stations in either the upper/lower or both half-slot locations. 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 Keyphasor module (three Keyphasor modules total) is also possible.
- In such a case, the user can configure the single non-paired Keyphasor (order either two 2-channel or one 1-channel and one 2-channel option) The Isolated Keyphasor I/O module is intended for situations in which the Keyphasor signals are connected in parallel to many devices and require separation from other systems, such as a control system.
- The Isolated I/O module was designed primarily for Magnetic Pickup applications, although it is compatible with and will offer isolation for Proximitor applications as long as an external power supply is provided. It should be noted that the purpose of this I/O module was to measure shaft speed rather than phase.
- The module can provide phase measurements, although this I/O introduces a somewhat larger phase shift than the NonIsolated I/O version.
