Metso D201126L (DI8P) – Meesoo Digital Input Module

Metso D201126L (DI8P) – Meesoo Digital Input Module
I. Basic Information
Brand: Metso (now part of Valmet after the automation business was separated)
Full model: DI8P D201126L
Product type: 8-channel PNP type digital input module (Digital Input Unit)
System affiliation: Metso/Valmet D series DCS control system, mainstream IO cards for papermaking, pulp production, and power plants

Core Electrical Specifications
Channel Configuration
8 Digital Inputs DI8, PNP high-level active
Rated Power Supply: DC24V, Current per channel approximately 40mA
Isolation and Protection
Electrical isolation between channels and system bus, resistant to on-site surges and interference
Wide Temperature Operating Range: -20℃ ~ +60℃, suitable for paper-making humid and power plant high-temperature cabinet environments
Hardware Structure
Rack-mounted front-insert card, standard D-series backplane bus slots
Panel equipped with operation, fault, transmission and reception status indicator lights (RUN/FAULT/TX/RX)
Weight approximately 0.4kg, compact rack IO board

Differentiation of the Same Series (DI8P / DI8N)
D201126L DI8P: PNP input, sensor output triggered by high-level signal (European standard NPN/PNP commonly used)
D201127L DI8N: NPN input, triggered by low-level signal, both have the same hardware shape and cannot be interchanged with program logic

Function and Usage
Collect on-site passive contacts, limit switches, proximity switches, valve feedback, motor operation/fault dry contact signals;
Upload switch status to DCS controller, used for interlock, sequential control, and equipment status monitoring;
Typical industries: Paper-making and pulping production line, thermal power plant, biomass energy, chemical process DCS.
