Description

IS200ECTBG1ADE GE Mark VI Exciter Contact Terminal Card

Overview

IS200ECTBG1ADE is the ECTB exciter contact terminal card built for the GE Speedtronic Mark VI control platform. It works inside EX2100 and EX2100e excitation cabinets as an interface between field hard wiring and the EMIO exciter main I/O board. The board routes trip contact signals, auxiliary status inputs and relay output signals for generator excitation protection.

🚀Function & Features

- Routes field contact signals to the EMIO board through D-Sub connectors
- Carries 2 trip lockout relay outputs for excitation trip circuits
- Provides 4 Form-C general-purpose relay outputs for auxiliary control
- Accepts 6 wet contact input channels for equipment status feedback
- Integrates 70 VDC wetting supply for dry contact sensing
- Includes onboard LED indicators for channel and power status
- Adds electrical isolation between field wiring and control logic circuits
- Matches chassis mounting layout of standard EX2100 cabinet assemblies
- Supports signal distribution for Mark VI excitation protection logic

Questions & Answers

💡 FAQ

Q: Can IS200ECTBG1ADE serve as a drop-in replacement for IS200ECTBG1A?

A: The physical footprint is identical. Pin mapping stays consistent, but the EX2100 firmware may require upgrade to match the new board revision.

Q: Does this exciter contact terminal card work in simplex excitation systems?

A: No. IS200ECTBG1ADE is designed for TMR triple redundant Mark VI excitation racks. It cannot run in simplex configurations.

Q: Are the relays soldered on the board or socketed?

A: Relay components are soldered onto the PCB. Individual relay replacement on the board is not supported in field maintenance.

Q: What is the payment method?

A: T/T

Q: What is the warranty?

A: 1 year

Q:What are the available shipping methods?

A: FedEx, DHL, UPS, and others.
