Product Overview
The Bently Nevada 81545-01 XDUCR I/O and Recording Terminals are precision-engineered interface components used to connect vibration transducers—such as proximity probes, velocity sensors, and accelerometers—to monitoring or recording systems. This module /fers a streamlined interface for signal transmission without integrated relay functions, making it suitable for applications focused on real-time monitoring, diagnostics, and trend recording rather than active protection or shutdown responses.
Designed for compatibility with Bently Nevada’s advanced monitoring systems, the 81545-01 provides stable, shielded signal pathways in a compact, DIN-rail-mountable form. It ensures that raw sensor signals maintain integrity from the machine to the data acquisition system, allowing accurate analysis / dynamic machine conditions.

よくある質問 (FAQ)
1. What is the main function / the 81545-01 module?
It serves as a signal interface terminal for transducers, facilitating clean signal transfer to recording or monitoring systems.
2. Does this module include relays for shutdown or alarm purposes?
No, the 81545-01 is a non-relay version intended for monitoring and data acquisition only.
3. What types / sensors can be connected to this terminal?
It supports proximity probes, accelerometers, and velocity sensors commonly used with Bently Nevada systems.
4. Does it require external power to function?
No, it is a passive terminal module and does not require power.
5. Can this terminal be installed in outdoor environments?
It must be installed inside a protective enclosure; it is not weatherpro/ by itself.
6. Is it compatible with the Bently Nevada 3500 system?
Yes, it is designed to interface cleanly with Bently Nevada monitoring platforms including the 3500 series.
7. Can the signals be connected directly to a PLC or DCS?
The signals are raw and may need to pass through appropriate conditioning modules before reaching PLC/DCS systems.
8. How does this differ from 81544-01?
While similar in function, model numbers /ten reflect configuration differences; consult datasheets to confirm specific compatibility.
9. Is this product suitable for safety-critical applications?
Yes, for monitoring purposes; however, active trip functionality requires separate relay modules.
10. How many channels does it support?
The exact number depends on configuration and use case—typically supports multiple input/output channels per 台.
