Product Overview

CE4035S2B4 is signal‑interface board for Cegelec / Alstom large DC drive cabinets. It conditions and isolates motor‑current feedback, armature‑voltage feedback, encoder pulse signals and interlock discrete‑contacts, transmits processed signals to main control‑board CE4003S2B6. Critical intermediate signal‑processing hardware for rolling‑mill, paper‑machine and metallurgy‑industry DC main‑drives. Discontinued spare component, refurbished and surplus tested hardware for legacy heavy‑industry drive‑cabinet repair‑projects.

Application Notes

‑ Observe strict ESD protection rules during card replacement. ‑ Verify field‑signal wiring and terminal‑connection integrity. ‑ Perform signal‑loop check after module installation. ‑ Typical deployment: heavy‑industry DC‑drive signal‑interface‑board spare‑part stocking.
