Features:
- Separates panel field wiring from the monitoring rack by routing transducer signals through external termination blocks.
- Delivers regulated +23.0 Vdc sensor power with individual channel current restriction set to 24.5 mA maximum.
- Provides front-accessible, inverted, and offset buffered output channels designed for real-time diagnostic instruments.
The Bently Nevada 143737-01 serves as the external termination interface module for the 3500/77M Recip Cylinder Pressure Monitoring system. It is installed in a single full-height rear slot of the 3500 machinery rack to collect dynamic pressure signals from reciprocating compressors.
Unlike internal termination modules, the 143737-01 architecture is built for environments where field wiring must terminate at remote DIN-rail terminal strips. Dynamic dynamic pressure data is transmitted securely from external sensors to the 3500 monitor backplane for protective alarm evaluation.
Please note that external termination blocks (such as model 125808-10 or 128015-10) and 129525 connection cables are required hardware components that must be specified separately when deploying this module.
Availability The Bently Nevada 143737-01 Cylinder Pressure I/O Module is available for shipment with original factory-level specifications guaranteed by the manufacturer (OEM).
