GE IS200LSGIH1A EX2100e Static Starter Gating Interface Card

Description

Product Overview

The General Electric IS200LSGIH1A is a Static Starter Control Gating Interface for the EX2100e excitation system. It connects the UCSB controller to power conversion bridges. Its main job is to provide instantaneous overcurrent protection without needing the controller. During a fault, it opens the 52SS relay to cut power and protect your system.

This board works with three FGPA boards to control six thyristors on each bridge. It receives 28V DC from the main supply and distributes power to the UCSB, LSTB board, and 8-port switch. The IS200LSGIH1A also passes ±24V DC to the FCSA board to power LEMs. A copper wire connects to a 12-pin plug for signal transfer between the FCSA and LSGI.

Use the GEH-6373 Load Commutated Inverter User’s Manual for installation and daughterboard setup.

FAQ – Frequently Asked Questions

What is the main function of IS200LSGIH1A?
It provides overcurrent protection and gating interface between UCSB and power bridges.

What voltage does this board need?
It needs 28V DC from the main power supply.

Can I use it without daughterboards?
Yes. The board works stand-alone but supports daughterboards for more I/O.

How do I know if the board is faulty?
Check the 12-pin plug voltage (±24V DC). Also monitor SCR data from FGPA.

Which manual covers installation?
Use GEH-6373 Load Commutated Inverter User’s Manual.

How fast does overcurrent protection work?
It opens the 52SS relay immediately, independent of controller scan time.

经验性问答: What fails often on this board?
Most issues come from loose 12-pin copper wire or damaged Augat connector pins. Always secure locking clips.

选购指导: Which redundancy option fits my budget?
Choose Redundant Control, Simplex Bridge for low cost and higher MTBFO. Pick EX2100e Control WBU if you need N+1 power bridge redundancy without a second PCM.

选购指导: Do I need the FHVA card?
Yes for full SCR voltage monitoring. The LSGI receives data from FGPA which gets it from FHVA.

Can I ship this board internationally?
Yes. We use FedEx, UPS, DHL with tracking and insurance.

What is the warranty period?
12 months from invoice date covering manufacturing defects.
