IS200DAMEG1A

Part Number IS200DAMEG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockThe IS200DAMEG1A is a gate amplifier/interface board developed by General Electric as part of the GE drive control system. This board connects power switching devices in the Innovation Series control rack. Designed specifically for low-voltage drives, it interfaces between IGBTs (Insulated Gate Bipolar Transistors) and the control rack. Notably, the board lacks test points, configurable items, or fuses and serves as an interface without amplification or power input. Features Interface Without Amplification: The DAME board connects IGBT power switching devices to the control rack without amplifying signals or requiring power input. It is one of six board variations and is rated for drives with 65 frames. Single Board for Three Phases: The DAME board is designed for use with phase leg drives, and a single board can interface with all three phases. Although different IGBTs are used per phase leg, this board includes only one IGBT module for all phases. Input/Output Connections: The board features three connectors (CPL for phase C marked as U, BPL for phase B marked as V, and APL for phase A marked as W) for connection with the Bridge Personality Interface (BPIA) board. Pin Descriptions: The board has six connectors, with each pin serving different functions. For instance, pin five (_PCOM) is a common pin that connects to the emitter of phases in the upper IGBT model. Replacement Requirements: If the board needs replacement, both the DAME board and IGBT must be replaced together since they are soldered together. Ensure the power is turned off before removal or insertion to prevent electric shock. Product Attributes Signal Input: The board receives low-level input signals from field devices (sensors, switches, etc.) and amplifies them for further processing. Amplification: An onboard amplifier boosts the input signal to a level suitable for control system processing. Isolation: Electrical isolation is provided between the input and output signals, protecting the control system from electrical noise and surges. Signal Output: The high-level output signal can trigger alarms, control motors or valves, or interface with a PLC or DCS system. Protection: Overvoltage and short-circuit protection features safeguard connected equipment. Board Replacement Procedure Ensure the drive has been deactivated. Open the cabinet door. Use high-voltage equipment to test circuits, ensuring power is off. Place the heatpipe heat exchanger assembly and IGBT modules (with DAME boards) directly below. Disconnect cables from the APL, BPL, and CPL connectors and move them aside. Disconnect the nuts, washers, and spring lock washers holding the shunt cables to the IGBT studs. Reposition the cables to avoid interference during board removal. Remove the two nuts, washers, and spring lock washers holding the outer flex circuit to the IGBT studs. Remove the four Allen-head bolts and washers holding the IGBT module to the heatsink, and remove the module and board. Unscrew the IGBT modules seven studs, washers, and spring lock washers. To Install the IGBT Module with Board Install the seven studs, washers, and spring lock washers in the new IGBT module with DAME board and fully tighten them. Apply an even layer of Dow Corning 340 silicon grease (or equivalent) to the IGBT module's back mounting surface. Insert the four Allen-head bolts and washers, and mount the IGBT module to the heatsink in the same position as before. Tighten the bolts in a diagonal pattern to 40 inch-pounds torque. Reattach the flex circuits to the mounting studs with nuts, washers, and spring lock washers. Reinstall the shunt cable assemblies on the IGBT module studs. Reconnect cables to the new DAME board芒聙聶s connectors (APL, BPL, CPL). Inspect connections and drive cabinet for any tools or debris before closing the cabinet door. Output Processing System outputs are portions of calculated data transferred to external hardware interfaces and actuators that control the process. The output voting hardware votes on TMR (Triple Modular Redundant) outputs. Signals are calculated independently by the three controllers, and a voting mechanism combines them into a single output. Output signals are categorized into three types: non-redundant individual I/O network outputs, outputs merged into a single signal by output hardware, and outputs routed separately to the controlled process via external voting hardware. For critical protective signals, a voting relay driver feeds three independent signals into relays with a six-contact voting configuration.GATE DRIVE CARD,68A
