Functional Description
3500/42-PWA125672-02 is a Discrete I/O Module manufactured by Bently Nevada. It is a part of 3300 XL series. It is specifically designed for use with Proximitor/Seismic monitoring systems to provide machinery protection and vibration monitoring for rotating machinery systems. This module plays an essential role in continuously monitoring machine vibrations, ensuring that operators and maintenance personnel are informed of any issues that may affect machinery performance.
Features
- Internal Termination I/O Module: Transducers and recorders need to be wired directly to the I/O module itself. This configuration simplifies the wiring process as it eliminates the need for external termination boxes and helps streamline the installation of the system.
- Channel Configuration: The I/O module is designed to support up to 4 channels. For each pair of channels (Channel 1 and 2, Channel 3 and 4), users can connect the transducer wires directly to the module. The wiring for each channel is done using the Euro Style connectors, ensuring secure and reliable connections.
- Jumper Selection for Transducer Type: To ensure proper operation, the module includes jumpers for each pair of channels (Channel 1/2 and Channel 3/4). These jumpers allow users to select the type of transducer that is connected to the module, such as Proximitor or Seismic transducers, ensuring compatibility and accurate data acquisition.
- INHB/RET and COM/REC Connections:
- INHB/RET (Inhibit/Return): This terminal is used to connect an external switch that inhibits all non-primary Alert/Alarm 1 functions for all four channels. It is typically used for maintenance purposes or when certain functions need to be temporarily disabled.
- COM/REC (Common/Recorder): This terminal connects each channel to the I/O module. It is used for routing signals from the transducers to the module, ensuring accurate vibration readings.
- Continuous Vibration Monitoring: The primary function of the I/O Module is to provide continuous machinery protection. By constantly comparing the machine's current vibration against configured alarm setpoints, the system can trigger alarms when vibration levels exceed predefined limits. This real-time monitoring is critical for preventing damage to machinery due to excessive vibration, misalignment, or other issues.
- Alarm and Setpoint Configuration: The I/O Module works in conjunction with the 3500 Rack Configuration Software to allow operators to configure alarm setpoints for each active proportional value. The software enables operators to set danger levels for vibration thresholds. Two of the proportional values can be configured with danger setpoints, ensuring comprehensive protection of the equipment.
LED Indicators for Status Monitoring
The front panel of the Proximitor/Seismic Monitor is equipped with several LED indicators that provide real-time feedback on the module’s operating status:
- OK LED: This indicator shows that the Proximitor/Seismic Monitor and the I/O Module are functioning correctly.
- TX/RX LED: This LED flashes at the rate of messages being transmitted and received between the monitor and the module, indicating communication activity.
- BYPASS LED: This LED shows when certain monitor functions are temporarily suppressed, typically for maintenance or troubleshooting purposes.

FREQUENTLY ASKED QUESTIONS
What is 3500/42-PWA125672-02?
It is a Discrete I/O Module manufactured by Bently Nevada.
How do I connect the transducers to the module?
The module uses Euro-style connectors for wiring transducers directly to the module. You will need to wire the transducers to the connectors for each respective channel. The module has jumpers that allow you to select the type of transducer (Proximitor or Seismic) for each channel.
What does the INHB/RET terminal do?
The INHB/RET terminal connects to an external switch used to inhibit non-primary Alert/Alarm 1 functions for all channels. This feature is often used for maintenance purposes or to suppress certain monitoring functions temporarily without affecting the primary alarm.
