Detailed Product Overview
The Metso D201139L is a dedicated power supply module used within Metso Automation systems. It converts incoming AC mains power into the regulated DC voltage required by control electronics, I/O assemblies, and related system modules.
The unit is commonly listed under the dual designation D201139L and DDC7940-D201139L. It is designed for fixed mounting in industrial control cabinets and forms part of the power distribution infrastructure of Metso DNA or earlier Damatic-based automation platforms.
Because the module supplies critical system power, correct upstream protection, proper grounding, and adequate ventilation must be observed according to the host system documentation. The module itself contains no fieldbus or communication interfaces; its sole function is AC-to-DC power conversion for the control system.
Replacement requires confirmation that the exact order code matches the installed unit, as different power supply variants exist within the Metso product range.
