IS200EROCH2A GE EX2100, EXCITER REGULA. OPTION CARD

Description:

Functional Description
The IS200EROCH2A is an Exciter Regulator Options Board developed by General Electric (GE). It forms part of the broader EX2100 system. This board plays a crucial role within the EX2100 regulator control systems, providing essential regulatory functions. Specifically engineered to ensure precise control and regulation of excitation systems, it meets the stringent demands of industrial power generation applications.

Features
Mounting and Interface: The EROC is designed for seamless integration into either the Exciter Regulator Backplane (ERBP) or the Exciter Regulator Redundant Backplane (ERRB), occupying a single slot. Its compact design and standardized interface facilitate easy installation and compatibility with existing control systems.
Board Identification and Compatibility: The EROC includes a sophisticated board identification (ID) device that communicates seamlessly with the M1 or M2 control associated with the specific backplane slot. This ID device contains critical information such as the barcode serial number, board type, and hardware revision, ensuring accurate identification and compatibility with the control system.
Power Status Indicator: A prominent green LED on the faceplate serves as a power status indicator, illuminating when power is applied to the card. This visual cue enhances operational visibility, allowing for efficient monitoring and troubleshooting.
Version Differentiation: Available in two versions—EROCH1 and EROCH2—each version offers specific features tailored to different application requirements or system configurations. This versatility enables users to select the appropriate EROC variant based on their operational needs and control system specifications.
Reliability and Performance: Engineered to withstand the harsh conditions of industrial environments, the EROC uses robust components and advanced circuitry to ensure reliable performance under various operating conditions. Its high-quality construction and adherence to stringent quality standards contribute to its exceptional reliability and longevity.
Keypad Connectivity
The Exciter Regulator Options Card (EROC) features two keypad connectors, one on the faceplate and another on the backplane (for both ERBP simplex and ERRB redundant configurations). These connectors support keypad data transmission for system control through bezel-mounted keypads.
While the EROC can transmit data to both connectors, only one keypad can be connected at a time. This dual connector setup accommodates various mounting configurations of the EX2100 regulator control. Communication between the EROC and the keypad connectors utilizes the RS-232C protocol, with baud rates ranging from 1200 to 38,400.
Tool Connector and Interface
The EROC includes a tool connector on its faceplate, serving as an interface point for connecting an external computer to the IS200DSPX Digital Signal Processor Control board (DSPX).
This connection is established via a 9-pin plug connector and supports communication protocols using RS-232C, with baud rates ranging from 1200 to 38,400. The tool connector enables seamless communication between the EROC and external computing devices, facilitating system monitoring, configuration, and diagnostics.
Ground Loop Isolation
To ensure robust and reliable operation, the EROC incorporates ground loop isolation for the tool connector through a dc/dc converter. This feature mitigates potential ground loop issues, enhancing system stability and performance during operation.
ECTB Connector
The EROC also includes an ECTB connector, which supplies positive 70 V dc power to the contact output section of the Exciter Contact Terminal board (ECTB).
This connector powers and interfaces with the ECTB, enabling seamless communication and control between the EROC and the contact output section of the ECTB. This integration facilitates efficient coordination and management of exciter contact terminal functions within the overall excitation system.
