Description
The Bently Nevada 133442-01 is a rear-panel I/O interface module designed specifically for the 3500/50M Tachometer Module within the 3500 Machinery Protection System. This module features integrated internal terminations, which eliminate the requirement for external termination blocks, thereby simplifying field wiring and reducing installation complexity in critical machinery monitoring applications.
Features
- 2-Channel I/O interface for 3500/50M Tachometer modules.
- Internal termination design eliminates the need for external terminal blocks.
- Supports direct connection of proximity probes or magnetic pickups.
- Provides buffered transducer outputs for signal distribution to external monitoring equipment.
- Includes relay output terminals for alarm status indication and control logic integration.
- Supports conditioned Keyphasor signal distribution via the 3500 rack backplane.
Applications
- Upstream Production: Offshore/FPSO pumps, compressors, and turbines.
- Refineries: FCCU and H2 compressors, crude pumps.
- LNG Plants: Refrigeration/methane compressors and cryo expanders.
- Pipeline Stations: Remote booster stations for oil and gas transmission.
- Power Generation: Thermal, combined cycle, and hydroelectric turbines and generators.

Installation Guidelines
- Ensure the 3500 rack is powered down before inserting or removing any I/O module to prevent electrical shock or transient damage.
- Align the module with the guide rails at the rear of the 3500 rack, corresponding to the front-facing 3500/50M monitor.
- Slide the module into the chassis until the backplane connector is fully seated.
- Secure the module by tightening the top and bottom thumb screws to ensure proper chassis grounding.
- Note: This module is not compatible with external termination blocks; it is designed strictly for internal termination configurations.
FAQ
What is the 133442-01?
The Bently Nevada 133442-01 is a 2-channel Tachometer I/O module with internal terminations, designed for the 3500 Series machinery protection system.
What is the function of the 133442-01 module?
It serves as the rear-panel interface for the 3500/50M Tachometer Module, supporting two channels of input (proximity probes or magnetic pickups) and providing buffered signals and relay outputs.
Does this module support Keyphasor signals?
Yes, when paired with the 3500/50M module, it can be configured to supply conditioned Keyphasor signals to the 3500 rack backplane for use by other monitoring modules.
Can I use External Termination Blocks with this module?
No. The 133442-01 is specifically designed for internal terminations and is not compatible with external termination blocks.
