System compatibility

Designed for Yokogawa CENTUM VP DCS distributed control system,collect 4-20mA signal from pressure,flow,temperature,level transmitters,widely used in petrochemical,power,chemical and refining process control.

Function

AAI143-S00 is 16-channel isolated analog input module without HART function.It converts 4-20mA field analog signal into digital data and transmits to FCS controller.Channel can be set for 2-wire or 4-wire transmitter individually.No digital HART communication,only analog signal acquisition.

Installation

Install on CENTUM VP FCS node unit backplane,connect field transmitters via pressure clamp terminal block or MIL connector cable,configure parameters by CENTUM VP engineering software.Hot swap supported.

Interface

‑Field signal terminal connector

‑Internal ESB bus backplane connector

‑LED indicators for run,alarm and channel fault

Circuit feature

Channel isolation design,anti-interference,overcurrent protection,continuous self-diagnosis,stable for harsh industrial environment.

Feature

AAI143-S00 belongs to Yokogawa CENTUM VP FIO series DCS I/O module,non-HART standard version.Common faults:terminal contact poor,cable damage,input circuit failure.Verify firmware version before replacement.

Diagnostic

Wire break,overrange,overcurrent or module hardware fault triggers alarm and upload diagnostic message to DCS controller.

Built‑in function

Collect process analog signals for DCS control system,used for industrial DCS spare replacement.
