Metso D201136 Control Module

Metso D201136 Control Module (DCS / PLC Hybrid I/O Control Module – D20 Series Family)

The Metso D201136 is a Metso/Valmet DNA DCS system module, typically belonging to the D20 series I/O control platform. Depending on system configuration, it is commonly used as a PLC/DCS hybrid I/O module (often analog input/output or mixed signal control module in rack systems).

Product Information

• Brand: Metso (Valmet)
• Model: D201136
• Series: D20 / DNA DCS platform
• Type: Control / I/O module (PLC/DCS hybrid architecture)
• Function: Signal processing, I/O handling, process control interface
• Installation: Rack / backplane module (not DIN rail standalone)

What it actually is

The D201136 is part of a modular distributed control system, meaning:

• Works inside a DCS rack cabinet system
• Communicates via backplane bus
• Handles process signals (analog and/or digital depending configuration)
• Interfaces between field devices and the main control system

Some sources describe it as:

• Analog input module (A04 / AI-type family)
• Or mixed PLC/DCS control module depending on revision and plant configuration

System Role (Simple)

Field instruments (sensors, transmitters, switches)
→ I/O processing modules
→ D201136 control module (this unit)
→ DCS controller system
→ operator station / plant control system

So it acts like a “core signal processing or interface module inside a DCS rack.”

Key Features (typical D20 family behavior)

• Rack-based plug-in module design
• High reliability for continuous 24/7 operation
• Industrial signal processing (analog / digital depending version)
• Backplane communication with system controller
• Designed for harsh process environments
• Modular replacement within DCS cabinet

Typical Applications

• Pulp & paper plants (Metso core industry)
• Oil & gas process control systems
• Chemical production plants
• Power generation systems
• Water treatment automation
• Large-scale industrial DCS installations

Advantages

• High system stability in DCS architecture
• Modular plug-in replacement (easy maintenance)
• Long lifecycle industrial design
• Suitable for continuous process control
• Integrates tightly with Metso DNA systems

Important Notes

• Not PLC standalone CPU ❌
• Not sensor ❌
• Not power supply ❌
• Not communication switch/router ❌
• It is a DCS rack I/O or control module (system-level component) ✔

Precautions

• Must be used in compatible Metso/Valmet DCS rack system
• Not interchangeable with generic PLC modules
• Requires correct backplane system configuration
• Version/revision compatibility is critical (D20 platform variants)
• Do not operate outside specified rack architecture
