Product Title

METSO D201190L – Analog Output Module

Product Overview

The METSO D201190L is an industrial analog output interface module engineered for process control and automation systems. It is part of Metso’s I/O module portfolio used in distributed control systems (DCS), PLCs, and machine automation platforms where conditioned analog signals must be generated and sent to field devices such as control valves, actuators, and analog indicators.

This module converts digital command values from a controller into high‑accuracy analog output signals (typically 4–20 mA or 0–10 V), enabling precise control of field devices and continuous process regulation. The METSO D201190L offers stable signal generation, per‑channel isolation, and robust noise immunity—ensuring reliable actuation even in electrically harsh industrial environments such as minerals processing, pulp & paper, water treatment, and chemical production.
