GE IS200EPCTG1AAA Product Description

The IS200EPCTG1AAA is an Exciter PT/CT terminal board designed for GE EX2100 excitation control system and Mark VI Speedtronic turbine control platform. This rack‑mounted printed circuit board serves as the front‑end signal conditioning interface for generator voltage and current measurements. It accepts raw signals from generator potential transformers (PT) and current transformers (CT), provides galvanic isolation, signal scaling and noise filtering, then transmits conditioned measurement data to EMIO main board for excitation closed‑loop calculation and generator regulation. Built for power generation environments, it features isolation transformers, surge protection components and multiple test points for commissioning and troubleshooting.

Product Features

• Dedicated PT/CT signal acquisition: supports two sets of three‑phase PT voltage inputs and two sets of generator CT current inputs
• Built‑in isolation transformers delivering galvanic isolation to protect control electronics from high‑voltage transients and fault surges
• Integrated surge suppression components including MOV devices to mitigate power‑system noise and transient disturbances
• Multiple onboard test points and jumper settings for convenient on‑site calibration, signal verification and diagnostics
• Rack‑mount form factor, directly plug‑in compatible with EX2100 excitation rack backplane
• Conditions raw PT/CT signals into low‑level standardized signals for downstream EMIO processing
• Wide industrial operating temperature range, suitable for continuous operation inside turbine control cabinets
• Supports redundant hardware configuration for high‑availability generator excitation control applications

Application Scenarios

• EX2100 generator excitation control systems for steam turbine power plants
• GE Mark VI Speedtronic gas turbine generator control cabinets
• Utility‑scale thermal power generation main generator voltage regulation loops
• Combined‑cycle power plant excitation signal measurement and conditioning subsystems
• Industrial captive power plant generator control and protection signal interfaces
• Retrofit and spare‑part replacement for existing GE turbine‑generator control racks
• Co‑generation facilities requiring high‑reliability generator excitation monitoring
