Metso D201126L – DI8P 8-Channel Digital Input Module
Product Overview
The Metso D201126L (DI8P) is an industrial-grade 8-channel digital input module designed for Metso Valmet automation control systems. It collects discrete on/off signals from limit switches, valves, sensors and field devices, then transmits stable state data to DCS/PLC platforms. This module solves signal instability, poor anti-interference performance and difficult system integration issues in mining, pulp & paper, metallurgy and processing industries, supporting continuous reliable process monitoring and closed-loop control.
