Product Overview

LG1093AC01 is a plug‑in excitation control module for Honeywell  generator excitation systems. It performs closed‑loop field‑current regulation for synchronous generators, implements excitation adjustment, field‑loss monitoring and multiple excitation‑related protection functions. The module exchanges real‑time set‑points and status data with main controller via internal rack bus. Comprehensive channel‑level diagnostics capture excitation circuit faults for plant alarm interlock. End‑of‑life OEM excitation hardware; available as refurbished and new‑old‑stock spare parts for power‑plant generator‑excitation‑system maintenance and retrofit projects.

Application Notes

‑ Install inside matched Honeywell  excitation control rack. ‑ Strictly verify field‑current rating against actual generator excitation parameters. ‑ ESD anti‑static handling required during replacement. ‑ Typical deployment: thermal‑power‑plant, hydro‑power‑plant generator excitation cabinet spare‑part stocking.
