Product Introduction
The Bently Nevada 3500/42M‑01‑00 I/O Module (part number 128229‑01) is a specialized interface module designed to complement the 3500/42M‑01‑00 Proximitor/Seismic Monitor in the Bently Nevada 3500 Machinery Protection System. As an essential link between sensor modules and the backplane, this I/O unit manages connection, power distribution, and signal routing for proximity probes, accelerometers, velocity sensors, and optional 4–20 mA outputs.
Installed in the 3500 rack, the 128229‑01 enables each channel of its paired Proximitor/Seismic Monitor (the 3500/42M) to perform real-time tracking of shaft vibration, radial shaft position, casing vibration, and more. By supporting up to four channels of input and providing diagnostic feedback directly to the system, this I/O module significantly increases system reliability and simplifies field maintenance.

Frequently Asked Questions (FAQ)
1. What is the function of part number 128229‑01?
It’s the I/O interface that supports the 3500/42M monitor by routing sensor signals from the rack backplane.
2. How many sensor channels does it support?
The I/O module supports up to four independent sensor channels.
3. Can it drive analog 4–20 mA outputs?
Yes, each channel can optionally provide proportional 4–20 mA output alongside buffered dynamic signal.
4. Does it provide diagnostic feedback?
Yes. It delivers diagnostic flags—such as sensor ok/not ok, signal dropout—to the 3500 system.
5. Is hot-swappable functionality available?
Yes. It can be swapped with the rack powered, preserving system uptime.
6. Which sensors are compatible with this module?
Compatible with proximity probes (3300 XL, 7200), velocity sensors, and standard accelerometers.
7. How is the module configured?
Using the 3500 Configuration Software via the 3500/22M TDI interface without physical access.
8. Where is this module installed?
In the same rack slot as its paired 3500/42M monitor, acting as its sensor interface block.
9. What power supply is required?
It draws less than 5 W and is powered directly from the 3500 rack power system.
10. What happens if wiring is disconnected or a sensor fails?
The module flags a “not ok” condition via the 3500/22M diagnostics and can be configured to alarm or trip.
