Product Short Description
Product Introduction:
Metso D201134 is a high-performance 8-channel analog input module from the AI8/AI8C series, manufactured by Metso (now Valmet) for the DNA Distributed Control System. This module receives analog signals from field devices representing continuously varying physical quantities such as temperature, pressure, flow, liquid level, or voltage, and converts them into digital information for control system processing through high-precision Analog-to-Digital Conversion (ADC).

Working Principle:
Metso D201134 receives analog signals from field sensors representing physical parameters such as temperature, pressure, flow, liquid level, or voltage. The module’s high-precision ADC converts these analog signals into digital information. The digitized data is then transmitted to the central processor for monitoring, analysis, and control. The AI8C variant provides independent 24 VDC transmitter power for each channel, eliminating the need for external power supplies for 2-wire transmitters.
Advantages and Highlights:
-
8-channel independent analog input for multi-sensor monitoring
-
High precision with 12-bit/14-bit resolution
-
Wide signal type compatibility for flexible application
-
Independent transmitter power supply per channel (AI8C)
-
Cost-effective design (40% lower than high-end series)
-
Plug-and-play deployment with 20-minute configuration
-
35 mm narrow-body design for space-constrained cabinets
-
Overcurrent protection prevents sensor short-circuit damage
-
Seamless integration with Siemens S7-1200, Schneider M208, and主流 PLCs
