Product Overview

IS200TREGH1B is the termination‑board assembly for generator excitation‑regulator control‑loops used together with GE EX2100 excitation‑control and Mark VIe turbine‑control systems. It provides physical field‑wiring connection points for excitation‑system feedback‑measurements, regulator command‑signals and excitation‑interlock discrete‑status contacts, routing these signals to excitation‑regulator processing boards. It is widely applied on large‑utility generator‑sets for excitation‑voltage regulation‑control‑signal interface. Discontinued excitation‑system spare‑board available as refurbished and surplus tested PCB assemblies for power‑plant‑excitation‑cabinet maintenance‑workshops.

Application Notes

‑ Isolate high‑power excitation‑circuit wiring from low‑level control‑signal wiring to avoid noise coupling. ‑ De‑energise all excitation‑system power before terminal‑board maintenance work. ‑ Confirm signal‑jumper configuration matches generator‑excitation‑system design documentation. ‑ Typical deployment: power‑plant EX2100 / Mark VIe excitation‑regulator terminal‑board spare‑part stocking.
