The GE IS200ECTBG2A is an Exciter Contact Terminal Board manufactured by General Electric as part of the EX2100 series used in the Excitation control system. It serves as the interface for the excitation control system’s contact inputs and outputs. Here’s a breakdown of its key features and functions:

Functions:

·Supports Excitation Control System: The IS200ECTBG2A facilitates the operation of the EX2100 Excitation Control system by managing its excitation contact outputs and inputs.
·Two Variations: There are two versions: ECTBG1 for redundant control and ECTBG2 for simplex control.
·Trip Outputs: Two trip outputs are present on each board, typically used to drive a customer lockout managed by the EMIO board.
·General-Purpose Relays: The EMIO board also controls four general-purpose Form-C contact outputs.
·Auxiliary Contact Inputs: The ECTB monitors and powers (wets) six auxiliary contact inputs with 70 V dc.
·52G and 86G Contact Inputs: It also powers and monitors the 52G and 86G contact inputs using 70 V dc.
·Power Supply: Both M1 and M2 controllers supply power for redundant control.

Relay Control and Feedback:

·Trip Relay Outputs (Simplex/Redundant): ECTBG2 controls two trip relays, driven by the M1′s EMIO, often used for customer lockout drivers. Each lockout is driven by one relay with two parallel normally closed contacts, identified as K1M1 and K2M1 on the board.
·Redundant Control System (ECTBG1): Three inputs drive three relays in ECTBG1′s redundant control system, controlling a voting circuit with two out of three contacts.
