Product Overview
The Bently Nevada 81544-01 XDUCR I/O and Recording Terminals are part / the advanced signal interfacing components within Bently Nevada’s machinery protection and monitoring ecosystem. These terminals are designed specifically for connecting transducer (XDUCR) signals—such as those from proximity probes, velocity sensors, and accelerometers—to data acquisition or condition monitoring systems.
This model 81544-01 is a non-relay version, focusing purely on input/output and signal recording functionality, making it ideal for applications that do not require alarm relays or trip contacts. The module ensures low-noise signal handling, stable connections, and efficient wiring from field sensors to the main monitoring system or recording equipment.

よくある質問 (FAQ)
1. What is the function / the 81544-01 module?
It serves as a passive I/O terminal interface for connecting transducer signals to monitors or recorders.
2. Does it include relays or alarm outputs?
No, this model is strictly for I/O and signal recording—it does not include relay outputs.
3. What types / transducers can be connected?
Proximity probes, accelerometers, and velocity sensors from Bently Nevada and other vendors.
4. Is external power required?
No, the module is passive and does not require external power.
5. Can it be mounted on a DIN rail?
Yes, it is DIN rail mountable for easy integration in control panels.
6. Is the signal shielded?
Yes, terminals support shielded signal wiring to reduce electrical noise.
7. What systems is it compatible with?
Any monitoring or recording system that accepts raw transducer input.
8. Is this suitable for hazardous environments?
The module itself does not include intrinsic safety features; use with certified barriers where required.
9. Can I use this module to interface directly with a PLC?
It depends on the signal conditioning needs—typically it’s routed to monitors or intermediate conditioning modules.
10. What is the difference between this and a relay module?
Relay modules provide discrete output alarms or trips; this 台 is strictly for signal routing and recording.
