Product Details

The INIIT13 is instruction interface module for ABB Bailey INFI90 and Symphony Plus DCS system.

This INIIT13 module is an important network communication component of distributed control system.

It connects the INFI‑NET redundant token‑ring control network with various functional processor modules inside the cabinet.

It completes bidirectional transmission of process data, configuration download, interlock commands and fault alarm messages.

It adopts independent communication processing chip, will not occupy main controller computing resources, ensures real‑time performance of control loop.

Front‑panel indicator lights display power status and network communication running condition.

Built‑in hardware self‑diagnosis function can detect bus abnormality and module internal failure, output fault alarm signal.

Hot‑swap supported, convenient for on‑site maintenance and replacement.

Widely applied in thermal power plant DCS transformation and maintenance projects.

It is important spare hardware for INFI90 system overhaul, network communication debugging and defective INIIT13 module replacement.
