Functional Description

IS200JGPAG1AAB is a Ground and Power Board developed by GE. It is a part of Mark VIe control system. The ground and power board is a component within the control system architecture, especially in conjunction with the PCAA core analog module and TCAT terminal board. The board serves a dual role in the control system setup. Firstly, it facilitates the termination of shield wires, ensuring proper grounding and shielding of signals. Secondly, it provides power outputs for field devices, specifically designed to accommodate 4-20 mA inputs.

Features

• Mounting and Placement: The board is designed to be mounted adjacent to the core analog module, where shield wires are terminated. This strategic placement ensures proximity to the components it supports and simplifies wiring connections.
• Shield Wire Terminal Points: Features shield wire terminal points that can be directly connected to the underlying functional earth sheet metal or wired to a preferred grounding point. This configuration ensures proper grounding and minimizes electromagnetic interference (EMI) in the system.
• Field Device Power Outputs: One of the key functions of the board is to provide power outputs for field devices. It offers twelve individually regulated and protected 24 V outputs, each capable of powering a single 4-20 mA field device. This feature ensures a reliable and stable power supply to connected devices.
• Regulation and Protection: The 24 V field device power outputs provided by the board are individually regulated and protected. This means that each output is carefully controlled to maintain a consistent voltage level and is safeguarded against overcurrent or short circuit conditions, enhancing the overall reliability of the control system.
• Integration with Mark VIe Terminal Boards: Shares similarities with the JGND board offered as an option with other Mark VIe terminal boards. This compatibility ensures seamless integration within the control system architecture and provides users with familiarity and flexibility in configuration and wiring practices.

Installation

• Placement Adjacent to PCAA and TCAT Terminals: The board is installed adjacent to the terminals on the PCAA core analog module and TCAT terminal board. This positioning ensures convenient access to both shield wires and power connections.
• Power Supply Connection: Power is provided to the board through a cable connected from P1 to PCAA or TCAT. This connection ensures that the board receives the necessary power supply for its operation.
• Mounting Bracket and Grounding: It mounts on a sheet metal bracket that is at ground potential. When mounted with conductive hardware, such as metal screws or bolts, the ground path for JGPA shield wires is established through the mounting bracket itself. If an alternate shield wire grounding method is desired, the JGPA board may be mounted with non-conductive washers and hardware. This isolated mounting configuration allows for a separate ground path. In isolated mounting setups, the ground is defined by one or more wires connected from shield ground terminals to the desired ground location, ensuring proper grounding of the shield wires.
• Grounding Considerations: Proper grounding of the board and shield wires is essential for minimizing electromagnetic interference (EMI) and ensuring the reliability of signal transmission within the control system. Care should be taken to establish a secure and low-impedance ground connection, adhering to industry standards and guidelines for grounding practices.
• Compliance with Installation Requirements: During installation, it is important to comply with the manufacturer's recommendations and guidelines provided in the installation manual for the board. This ensures the proper functioning and longevity of the equipment.

Operation

• Power Supply Functionality: Functions as a power supply unit, delivering regulated 24 V DC power to the connected terminals on TB3. This power supply is essential for supplying electricity to various field devices or components requiring 24 V DC power for operation.
• Individual Terminal Protection: In the event of an overcurrent condition detected on one of the 24 V DC outputs, the board is designed to respond appropriately to prevent damage to the affected circuitry.
  When an overcurrent condition occurs on a specific 24 V DC output, only that particular output is shut down while the remaining outputs continue to operate normally. This selective shutdown mechanism ensures that the fault is isolated and does not affect the operation of other connected devices.
• Response to Overload Removal: Upon removal of the overload condition, the affected terminal automatically returns to its normal operating state, providing 24 V DC power as required.
  This automatic recovery feature ensures that normal operation resumes seamlessly once the fault condition is rectified, minimizing downtime and maintaining the functionality of the connected equipment.
• Reliability and Safety: Its ability to individually shut down overloaded outputs enhances the reliability and safety of the control system by preventing damage to components and minimizing the risk of electrical hazards.
  By promptly responding to overcurrent conditions and restoring power upon fault clearance, the JGPA board helps maintain the integrity and stability of the control system operation.
