140471-01 BENTLY NEVADA 3500/72M I/O MODULE 184139-01

BENTLY NEVADA 140471-01 PWA184139-01 I/O Module with Internal Terminations designed for use with the Bently Nevada 3500 Machinery Protection System and the 3500/72M Recip Rod Position Monitor. Installed at the rear of the 3500 rack, it provides the electrical interface between field devices and the monitor, supporting signal transmission and system integration for reciprocating compressor monitoring applications. The module is commonly used in oil and gas, petrochemical, chemical processing, power generation, and other industries where continuous monitoring of critical reciprocating equipment is required.

We provide clear identification of the complete part number, assist in confirming compatibility with existing 3500 system configurations, and support worldwide shipping for planned maintenance and emergency replacement requirements. Each module is checked before shipment, with product photos and packaging details available upon request to help reduce procurement uncertainty and simplify installation planning.

--Designed for the Bently Nevada 3500/72M Monitoring System

The 140471-01 I/O Module 184139-01 is designed to operate with the Bently Nevada 3500/72M Recip Rod Position Monitor, providing the electrical interface between field devices and the monitor within the 3500 Machinery Protection System.

--Rear I/O Module Configuration

Installed at the rear of the 3500 rack, the module provides field wiring connections and supports signal transmission between external devices and the front monitor module while maintaining the standard rack architecture.

--Supports Reciprocating Compressor Monitoring

The module is used in reciprocating compressor monitoring systems to transfer position-related signals required for machinery condition monitoring and protection. It is suitable for applications where continuous monitoring of compressor components is required.

--Compatible with Existing 3500 Rack Systems

Designed for integration into existing Bently Nevada 3500 systems, the module can be used for routine maintenance, scheduled shutdowns, spare parts inventory, and replacement of existing I/O modules with matching specifications.

--Complete Part Number Identification

Each module is supplied with clearly identifiable part numbers and product labels, making it easier to verify compatibility before installation and reducing the possibility of ordering incorrect spare parts.

--Worldwide Supply Support

Support is available for international shipments, product identification, compatibility verification, and quotation requests. Product photos and packaging information can also be provided before shipment upon request.

The 3500/72M Recip Rod Position Monitor, a four-channel device, receives signals from proximity transducers, processes these signals for dynamic and static position measurements, and then compares them to user-set alarms.

Depending on the configuration, each channel typically processes its input signal to produce different parameters known as measured values.

By utilizing the 3500 Rack Configuration Software, you can:

• Set alert thresholds for each active measured value and danger thresholds for any two active measured values.
• Safeguard reciprocating compressors by continuously monitoring parameters against set alarm thresholds, displaying alarms, and activating relays when necessary.
• Keep track of the condition of critical reciprocating compressor machinery. The monitor channels are programmable to meet specific requirements.

The 3500/72M Recip Rod Position Monitor complies with API 618 specifications for reciprocating compressors and is capable of measuring the following parameters:

• Rod position
• Rod drop
• Hyper-compressor functions
