Product Overview

The D201138L is a compact integrated digital I/O module exclusively developed for Metso DNA process DCS, marked as IBC series on the housing (IBC4 / IBC6 are internal version identifiers under the same D201138L part number). It consolidates discrete digital signal collection and on-off control output in a single DIN rail unit, serving as the direct field interface between DNA main controllers and on-site switching equipment.

It solves prominent automation system pain points in pulp & paper, fiber processing and chemical industries: excessive rack space occupation caused by separate DI and DO standalone modules, complicated multi-card wiring increasing wiring errors, lack of independent per-channel fault diagnosis for discrete loops, and lengthy production downtime during module replacement without hot-swap function. Pulp and paper plant instrumentation engineers, DCS maintenance technicians and process system integrators achieve streamlined cabinet layout and simplified troubleshooting with this Metso combined I/O module.
