Transition Mode Data Acquisition Interface (TDI) 146031-02:

The Transition Mode Data Acquisition Interface (TDI) 146031-02 serves as the interface between the 3500 monitoring system and the control program Machine System 1™ by Bently Nevada. The TDI, in combination with the Chassis Interface Module (RIM) 146031-02, performs several crucial functions:

• Functionality:
  • Collects data from communication processors like TDXnet™.
  • Installs in the chassis 3500’s RIM slot and connects to monitor M series (e.g., 3500/40M, 3500/42M) for continuous data collection, handling stable and transient fluctuations.
  • Transmits signals to the main program via Ethernet computers.
  • Collects static data, but activation channels using disks allow dynamic and transitional mode data collection.
• Improvements:
  • Compared to previous communication processors, the TDI brings several improvements.
  • Achieves common functions within the chassis but is not part of the critical monitoring path, ensuring normal system operation.
• Installation and Requirements:
  • Each chassis requires a TDI and RIM.
  • TDI is located in slot 1, next to the power slot.
  • Suitable for Triple Redundant Module (TMR) applications in 3500 systems, requiring the TMR version of the TDI processor.
• TMR TDI Processor:
  • Executes “Monitor channel comparison” in addition to standard TDI functions.
  • Continuously compares output signals of three redundant monitors in TMR configuration, marking a monitor as faulty if deviations are detected.
• Power Consumption:
  • Consumes 10.5W of power.
• Data Interfaces:
  • RS232 serial interface with a speed of 115.2 KB.
  • Ethernet I/O modules for 10 BASE-T/100 BASE-TX and 100 BASE-FX, providing versatile communication options.
• LED Indicators on Front Panel:
  • OK LED: Indicates successful operation.
  • TX/RX LED: Shows inter-module data exchange.
  • TM LED: Indicates the chassis in multiplication mode.
  • Module OK Relay I/O: Relay for normal working instructions or indicating discrepancies discovered in the chassis.
• OK Relay Parameters:
  • Up to 5A at 24 V DC/120 V communication.
  • 120 W/600 VA transmission power.
  • Normal closed contact to provide arc-extinguishing equipment.
