Product Overview

NXPP‑03C is pulse‑processor input module for ABB NX series DCS system. It receives pulse‑type signals from flow meters, speed sensors and encoders, converts frequency‑pulse signals into digital process values for DCS controller processing. Built‑in channel diagnostics detect abnormal input signals. This legacy DCS module is end‑of‑life; available as refurbished and new‑old‑stock spare parts for power‑plant and process‑plant DCS‑system overhaul projects.

Application Notes

‑ Install in matched ABB NX‑series DCS rack. ‑ Isolate field pulse‑signal cables from high‑voltage power cables to reduce interference. ‑ Apply ESD protection during module replacement. ‑ Typical deployment: thermal‑power‑plant DCS cabinet, chemical‑process‑plant pulse‑measurement spare‑part stocking.
