Product Title

METSO D201131L – High‑Speed Digital Output Module

Product Overview

The METSO D201131L is an industrial‑grade digital output (DO) interface module designed for process automation and control systems in demanding industrial environments. It is part of Metso’s modular I/O family used to interface control logic with field‑level actuators and devices. This module converts digital control commands from the automation system into discrete on/off signals that drive relays, solenoids, indicator lights, and other switched devices.

Built for reliability and electrical noise immunity, the METSO D201131L provides rapid execution of control logic, clear visual diagnostics, and robust protection, making it suitable for industries including pulp & paper, mining, chemical processing, energy generation, and water/wastewater treatment. Its standardized industrial design ensures seamless integration with distributed control systems (DCS), PLCs, and machine automation platforms.
