Background

Manufactured by ALSTOM (France). ALSTOM’s energy business was later incorporated into GE Power Conversion. H262‑R‑V1 is the hardware revision marking of this card. It is a rack‑mount plug‑in module for ALSTOM N700‑series control systems.

This part is EOL (End‑of‑Life / discontinued). Original OEM production has been terminated. Most available supplies on market are used or refurbished spare units. It is only for maintenance and replacement of legacy old‑equipment, not for new‑project deployment.
