Product Details:

Bently Nevada 79748-01N is an XDCR I/O Record Terminal Module, serving as the rear rack transducer input terminal block for Bently Nevada 3300 series turbine supervisory instrumentation system. It is designed to work with dual axial position monitors, providing reliable wiring terminals for eddy current proximity transducers, and responsible for receiving shaft thrust displacement signals from field probes. The 79748-01N transmits collected transducer signals to the main monitor board, and it can output analog recording signals for external data recorders, DCS and PLC control systems to realize continuous tracking of rotor axial thrust position. When the thrust position exceeds preset alarm thresholds, the terminal module supports relay contact signal output to trigger on-site alarms or safety interlock commands, protecting thrust bearings from excessive axial force damage. This terminal module adopts industrial reinforced terminal structure and conformal coated circuit board, which can effectively resist electromagnetic interference, mechanical vibration, dust and temperature changes in power plant and petrochemical sites. It maintains low signal attenuation and stable signal transmission performance during long-term continuous operation, ensuring accurate measurement of rotor axial movement. The 79748-01N adopts rear rack mounting design, supporting convenient wiring, installation and routine maintenance, perfectly matching the 3300 dual axial position monitor card. Widely used in power generation, petrochemical and metallurgy industries, this transducer terminal block is a vital component of rotating machinery protection system. It helps plant operators monitor turbine thrust bearing health status in real time, identify abnormal axial movement and bearing wear risks at an early stage, prevent severe mechanical collision and unplanned equipment shutdown, and support predictive maintenance of critical steam turbines, compressors and generators.
