On G1 boards, J1 serves as a factory test jumper for a programmable logic device input. However, on other board types, J1 may have alternative functions or purposes.

Power Supply

The power supply of the board plays a critical role in providing the necessary electrical power for the MBHA (Main Board Hardware Assembly) and ensuring reliable operation. Here are the expanded details about the power supply:

  • Switching Power Supply: The board is powered by a 100 kHz + 5 V dc switching power supply. A switching power supply is a type of power supply that utilizes high-frequency switching techniques to convert the input voltage to a stable and regulated output voltage.
  • Input Voltage Range: The power supply is designed to be compatible with a wide range of input voltages. It is typically powered by an unregulated 24 V dc source, which is commonly used in industrial applications. The power supply can accept input voltages ranging from 15 to 30 V dc, providing flexibility in connecting to different power sources.
  • Power Consumption: The power supply's power consumption is approximately 5 watts. This value indicates the amount of electrical power consumed by the power supply during operation. It is essential to consider power consumption to ensure proper sizing and compatibility with the overall power requirements of the system.
  • Redundant Inputs: The power supply features redundant inputs, which enhance its reliability and resilience. These redundant inputs are wired in a diode OR configuration. This means that multiple input sources can be connected to the power supply, and it will utilize the higher of the two input voltages. This configuration ensures continuous power supply even if one of the inputs fails or becomes unavailable.
  • Fail-Safe Operation: In case one of the two inputs fails, the power supply can still function. The diode OR configuration allows the power supply to seamlessly switch to the remaining operational input without interruption. This fail-safe operation ensures that the power supply continues to deliver power to the MBHA, maintaining the system's functionality and minimizing downtime.

The power supply's design, with its switching capability, input voltage range, redundant inputs, and fail-safe operation, provides a reliable and stable power source for the MBHA on the board. It allows for consistent and uninterrupted operation of the system, even in the event of a power source failure or fluctuation.

Fibre Optic Transmitter/Receiver Pair

  • The system offer high reliability, the Simplex via software-implemented fault tolerance, and the TMR using that and its triple redundant architecture. Ihe system offer a direct sensor interface, built-in diagnostics, online maintenance, and have a common hardware platform for steam and gas applications.
  • The card functions as a Line Protection board. The card is equipped with drill holes in each board corner as well as others along each edge. These allow for mounting options and can be populated by standoffs or by screws. The board also has a vertical female cable connector, stab-on connectors, two terminal strips, LED indicators, a reset switch, and a transformer component.

Mode Control

  • Includes three fiber-optic receivers (CIMODE, CZMODE, and C3MODE) for receiving mode control information (local/broadcast) from Hom individual drives.
  • The CIMODE and C2MODE receivers are 5 Mbaud data links, while the C3MODE link has circm'ts that reduce its bandwidth to 100 kbaud.

Configurable Hardware

  • It features a Berg-type jumper labeled IP1, which provides a hardware configuration option. This jumper serves a specific purpose related to manufacturing testing and should be configured accordingly for normal operation.
  • The Berg-type jumper, also known as a header jumper or pin header, consists of a plastic housing with a row of metal pins that can be inserted into corresponding sockets. In the case of the MBHA board, the IP1 jumper is utilized to modify the hardware configuration.
  • It is important to note that the IP1 jumper is primarily intended for manufacturing testing purposes and not intended for user-configurable options or operational adjustments. The specific configuration of the jumper for normal operation is to connect pins 1 and 2. This connection ensures the correct hardware configuration is in place, enabling the board to function as intended within the system.
  • The purpose of this configuration may vary depending on the specific requirements or design considerations of the board. It is designed to support proper initialization, calibration, or testing procedures during the manufacturing phase. By configuring the IP1 jumper in the prescribed manner, manufacturers can ensure that the board is ready for deployment and meets the required performance specifications.
  • For normal operation and use of the MBHA board, it is crucial to follow the recommended configuration by connecting pins 1 and 2 of the IP1 jumper. This ensures that the board operates in its designated mode and maintains compatibility with other components and systems within the overall setup.
  • It is worth noting that any modifications or alterations to the jumper configuration should only be performed by qualified personnel and in strict adherence to the manufacturer's guidelines and specifications. Any unauthorized modifications or improper configurations may lead to functionality issues, system errors, or potential damage to the board.
