Product Overview

AAI135‑S53 is 8‑channel isolated analog‑input module for CENTUM‑VP DCS platform. It acquires 4‑20 mA field‑transmitter signals from pressure, flow, level and temperature process instruments. Channel‑by‑channel isolation suppresses ground‑loop interference; built‑in wire‑break detection improves field‑loop fault diagnosis. Widely deployed in chemical, power‑plant and petrochemical process‑control cabinets. Surplus and refurbished tested spare I/O module for DCS‑rack maintenance‑projects.

Application Notes

‑ Use shielded twisted‑pair field‑cable for 4‑20 mA signal wiring. ‑ Perform channel calibration after module replacement. ‑ Typical deployment: CENTUM‑VP analog‑input‑module spare‑part stocking.
