Bently Nevada 3500/50 133442-01 Internal Termination I/O Module for Two-Channel Tachometer

Function Features

• Internal Termination for Simplified Wiring: The internal termination design cancels the need for complex external wiring between the tachometer module and sensors. It shortens the wiring distance, reduces the probability of signal interference and wiring faults, and improves the efficiency of on – site installation and later maintenance.
• Multi – Parameter Collaborative Monitoring: When paired with the 3500/50 tachometer module, it can realize comprehensive monitoring of multiple parameters such as rotation speed, rotor acceleration and rotation direction. It can detect zero – speed and reverse rotation states of equipment, which provides comprehensive data support for judging the operation state of machinery.
• Peak Hold and Data Recording: It supports the peak hold function together with the matching tachometer module. It can store the maximum speed, maximum reverse speed of the equipment or the number of reverse rotations. Users can reset the recorded data according to maintenance and analysis needs, which is convenient for tracking the extreme operation state of the equipment.
• Backplane Signal Sharing Support: It assists the tachometer module in outputting conditioned keyphasor signals to the 3500 rack backplane. This allows other monitoring modules in the same rack to directly obtain and use the signals, which optimizes the overall structure of the monitoring system and reduces the investment cost of additional keyphasor modules.
• Redundant Configuration Adaptability: It supports redundant power supply and rack configurations. When a power supply or rack component fails, it can quickly switch to the standby component to continue working. This ensures the continuous operation of the monitoring system and avoids monitoring interruptions caused by local failures.
• Intuitive Status Display: The front – panel OK, TX/RX and bypass LEDs can directly reflect the module’s operation status, communication status and whether it is in bypass mode. This enables operators to quickly identify faults and handle them in a timely manner, reducing the troubleshooting time.

Application Scenarios

• Power Industry: It is widely used in steam turbines, generators and water pumps in thermal power plants and hydropower stations. It cooperates with the 3500/50 tachometer module to monitor the rotation speed and acceleration of the equipment shaft. It timely alarms when abnormal conditions such as overspeed occur, preventing equipment damage and ensuring the continuous and stable operation of the power grid.
• Petrochemical Industry: It is applied to centrifugal compressors, screw pumps and other equipment in oil refineries and natural gas processing plants. It monitors the reverse rotation and speed fluctuation of the equipment. It avoids safety accidents such as pipeline leakage or material backflow caused by abnormal equipment speed and ensures the smooth progress of oil and gas processing and transportation.
• Metallurgical Industry: It is installed on rolling mills, blast furnace fans and crusher equipment in steel plants and non – ferrous metal smelters. It adapts to the harsh on – site environment with high dust and large temperature changes. It monitors the speed of the equipment in real time to ensure that the production process meets the set standards and reduces production interruptions caused by equipment failure.
• Marine Industry: It is matched with the 3500/50 tachometer module to be used in marine diesel engines and ship – borne power generation equipment. It can work stably in the marine environment with high humidity and salt fog. It monitors the rotation parameters of the power equipment to ensure the stable output of marine power and guarantee the safe navigation of ships.
• Heavy Machinery Manufacturing: It is used for speed monitoring of motors and transmission systems in large – scale engineering machinery such as excavators and cranes. It assists in ensuring that the transmission speed of the machinery meets the operation requirements during the construction process. It reduces mechanical wear caused by speed anomalies and extends the service life of the equipment.
