WESDAC D20M++ Substation controller

Description

D20 Substation Controllers:
The Ultimate in Field-Proven Reliability
D20 Main Chassis
The D20 main chassis comes in three distinct types tailored
to meet the varying size and communication requirements of
different automation projects from a few hundred points to over
75,000 SCADA points.
The D20 or D200 main chassis houses the central CPU(s) and
communication ports which provide the data concentration,
protocol conversion, and customizable local automation
functionality.
D20ME II CPU Board
The D20ME II is the sixth generation main processor for the D20
platform. This 32-bit main processor module handles data
collection and delivery to host computers, runs local automation
algorithms and maintains I/O and device data in the system
database.
