GE IS200ECTBG2A Exciter Contact Terminal Board for EX2100 System

The IS200ECTBG2A is an Exciter Contact Terminal Board (ECTB) from GE Industrial Solutions, designed for the EX2100 Excitation Control System. This board operates exclusively in Simplex Mode, unlike the G1 version, which is used in redundant configurations.

Key Features

• Simplex Mode Operation: The IS200ECTBG2A functions in Simplex Mode, offering a reliable, single-path solution for excitation control in the EX2100 system.
• Flexible Inputs and Outputs: It includes six auxiliary contact inputs, two trip contact outputs, and four Form-C relay contact outputs, providing versatile control options.
• Power for Wetting Contacts: The +70V DC supply from the EPSM Module powers the contact terminals, ensuring reliable operation even in demanding environments.
• Input Monitoring: The board monitors two specific inputs: 52G and 86G, facilitating comprehensive monitoring of system states.

Technical Specifications

Overview

The IS200ECTBG2A is an essential part of the EX2100 Excitation Control System from GE Industrial Solutions. Unlike the G1 version, which is designed for redundant systems, this model operates specifically in Simplex Mode, making it a perfect choice for single-path excitation control.

With six auxiliary contact inputs, the board provides an extensive range of monitoring capabilities. It offers two trip contact outputs and four Form-C relay contact outputs, enabling it to adapt to different control scenarios. Additionally, the board can monitor 52G and 86G contact inputs, enhancing its ability to oversee important system parameters.

Powering the contact terminals with +70V DC from the EPSM Module, the IS200ECTBG2A maintains stable performance even under challenging conditions. The board integrates seamlessly with other terminal boards, such as the EXTB, EACF, and EPCT, under the management of the EMIO board. The EMIO board collects input and output data, then sends logic signals over the backplane to the ESEL board, ensuring efficient communication within the EX2100 system.

For installation and operation, refer to the GEH-6632 EX2100 Excitation Control User’s Guide, or the GEI-100457 Exciter Contact Terminal Board Instruction Manual for detailed guidance on the IS200ECTBG2A.

Applications

The IS200ECTBG2A is ideal for:

• Excitation control applications in Simplex Mode.
• Monitoring and controlling discrete inputs and outputs in industrial automation systems.
• Integration with the EX2100 system to manage generator excitation and maintain optimal performance.
