Product Description

Description

The Bently Nevada 140471-02 is an I/O module designed for dynamic pressure monitoring applications in the 3500 Machinery Protection System. The module processes signal inputs from high-temperature pressure transducers to perform signal conditioning and pass data to the 3500/64M main monitor board. Featuring internal termination wiring connections, the 140471-02 routes transducer signals, provides transducer power supplies, and outputs proportional +4 to +20 mA recorder signals for external control systems.

Features

  • Direct internal termination connections for 3-wire and 2-wire pressure transducer inputs
  • Integrated transducer power supply routing, providing -24 Vdc for 3-wire transducers and 3.3 mA current source at 22 Vdc nominal for 2-wire transducers
  • Support for 4-channel signal routing to the 3500/64M Dynamic Pressure Monitor
  • Dedicated terminal connections for 4 to 20 mA proportional recorder outputs per channel
  • Configurable internal jumpers for selecting 2-wire or 3-wire transducer field wiring configurations

Applications

  • Gas turbine combustion dynamic pressure monitoring
  • Hydro turbine dynamic pressure measurement
  • Reciprocating compressor cylinder dynamic pressure monitoring
  • Industrial machinery protection and condition monitoring

Installation Guidelines

  • Verify internal jumper positions for each channel pair (CH1/CH2 and CH3/CH4) match the connected transducer type (2-wire or 3-wire) prior to wiring.
  • Ensure field wiring is landed securely on the appropriate internal terminal block header (e.g., 8-position, 6-position, or push-in spring type headers).
  • Connect cable shields directly to designated SHLD/SHIELD terminals to maintain electromagnetic shielding performance.
  • Mount the module into the rear slot of the 3500 rack directly behind the corresponding 3500/64M monitor main board.
