PRODUCT INFORMATION
Product Overview
The General Electric IS200EMIOH1A operates within the Mark VI / Mark VIe control series. This Exciter Main Input/Output board manages signal interfaces across multiple external terminal boards. It directly coordinates input and output data from ECTB, EACF, EXTB, and EPCT terminal boards. The hardware functions as a single-slot double-height-versa module Eurocard assembly.
The board transmits gate pulse signals from the backplane directly to the ESEL board. The ESEL board then routes these signals to the EGPA board in the power conversion cabinet. The unit controls contact inputs, pilot trip relay drivers, PT and CT signals, and output relay drivers. Connection to the EXTB board initiates de-excitation and provides control over the associated EDEX board. Front plate indicators include two diagnostic LEDs for visual status and power monitoring.
