IS200EROCHIA

Part Number IS200EROCHIA Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS200EROCHIA is an Exciter Regulator Options Card developed by General Electric for the EX2100 control system. It is used in EX2100 regulator control systems, available in both simplex and redundant configurations. This card is essential for regulating and controlling the exciter, ensuring optimal performance and stability. It is mounted into a single slot of either the Exciter Regulator Backplane (ERBP) or the Exciter Regulator Redundant Backplane (ERRB), depending on the system setup. Features Board Identification Device: Equipped with a board identification (ID) device that interfaces with the M1 or M2 control associated with the specific backplane slot. This device contains essential information such as the barcode serial number, board type, and hardware revision, facilitating proper identification and configuration. LED Indicator: A green LED indicator on the EROC faceplate illuminates when power is applied to the card, providing visual confirmation that power is reaching the card. Installation: Installed into a designated slot on the Exciter Regulator Backplane or Redundant Backplane, depending on the system configuration. Proper alignment and secure mounting ensure reliable operation and integration. Compatibility: Designed to work seamlessly within the EX2100 regulator control system, providing essential support for regulator functions. Its compatibility ensures smooth operation and reliable performance in regulating exciter functions. Keypad Connectors Features two keypad connectors, one on the faceplate and another on the backplane (ERBP simplex and ERRB redundant). Both connectors facilitate keypad data transmission, allowing connection to bezel-mounted keypads, although only one keypad can be connected at a time. The two connectors accommodate different mounting variations of the EX2100 regulator control system, ensuring compatibility with various installation setups. Communication between the EROC and the keypad connectors occurs via RS-232C protocol, supporting baud rates ranging from 1200 to 38.4 K baud. Ground Loop Isolation The EROC incorporates ground loop isolation for the tool connector through the use of a dc/dc converter, preventing ground loops and ensuring stable communication. Tool Connector The tool connector on the EROC faceplate interfaces with an external computer for connecting to the IS200DSPX Digital Signal Processor Control board (DSPX). Connection is made via a 9-pin plug connector, supporting communication with M1/M2 using the RS-232C protocol, with baud rates ranging from 1200 to 38.4 K baud. ECTB Connector The ECTB connector on the EROC provides a positive 70 V dc power supply to the contact output section of the IS200ECTB Exciter Contact Terminal board (ECTB), ensuring its proper operation within the exciter control system. Board Replacement Power Down: Ensure the board rack is deactivated to prevent electrical hazards during replacement. Safety Checks: Open the exciter control cabinet door and test electrical circuits to confirm that power is completely cut off before handling components. Labeling Cables: Check that all cables are labeled with their corresponding connector names to simplify the reconnection process. Disconnect Cables: Disconnect all cables, including redundant connections and ISBus cables if applicable. Carefully remove each cable to avoid damage. Removal of EROC: Unscrew the screws located near the ejector tabs at the top and bottom of the faceplate. These screws should remain captive in the faceplate. Raise the ejector tabs to unseat the board from the rack. Using both hands, gently pull the board out of the rack, being cautious not to damage the electronics. Ensure proper placement in the designated slot to avoid damage. Replacement: Slide the replacement EROC into the appropriate slot within the rack. Seating the Board: Firmly press both the top and bottom of the faceplate simultaneously with your thumbs to start seating the board. Securing the Board: Finish seating the board by evenly tightening the screws located at the top and bottom of the faceplate. Ensure the module is securely seated within the slot. Reconnection: Reconnect all cables that were previously disconnected during the replacement process.EXCITER REGULATER OPTIONS CARD
