GE D20 MIC 10BASE-T Servo controller

The Multilin D20/D200 Substation Controllers offer an industry leading design embedded with
high value substation automation applications that provide cost savings, increased reliability, and
improved operational efficiencies in electric power substations. The ability to support a wide range
of communication protocols and applications, allows the D20 to be interoperable with a broad range
of intelligent electronic slave and master devices. The D20 can execute simple to complex local logic,
compile and process data [collect and convert] and reports upstream to master stations. The D20’s
distributed, expandable I/O architecture and mission-critical automation control applications reinforce
why the D20 controller is being used in over 40,000 installations around the world.
Key Benefits
In a mission-critical substation-hardened package, the D20/D200 provides:
• Substation client and server functionalities by maintaining a distributed architecture for gathering
and controlling data on substation equipment while sending data to master stations via serial RS-232,
RS-485, fibre optic or Ethernet interfaces for point to point, multi-drop and remote connections.
• Support for a broad range of SCADA host protocols, IED protocols, Communication options, Input/output
(I/O) peripheral modules, and operation and maintenance utilities substation automation applications.
