D20/200ME Substation Controler - Legacy

Overview

Manufacturing for D20/200ME Substation Controllers have been discontinued. As alternatives, the supplier references G500 or D20MX/D200MX products. The D20 substation controller is described as an industry-leading design embedded with substation automation applications that provide cost savings, increased reliability, and improved operational efficiencies. It acts as the gateway to SCADA master stations for IEDs in the station, or for downstream substations or feeders, and includes a large protocol library to facilitate communication to most existing substation devices for improved visibility and remote control. The main chassis contains the central CPU(s) and communication ports and provides data concentration, protocol conversion, and customizable local automation functionality; available chassis options are: D20 main chassis - Single or 2 CPU options available, and D200 main chassis - Up to 7 CPUs. The product is described as having a distributed, expandable I/O architecture and mission-critical automation control applications and is reported to be used in over 40,000 installations around the world. D20 I/O options will remain available for use with G500 products. The D20 device is used as a gateway to SCADA master stations for IEDs in the station and for downstream substations or feeders. It provides data concentration, protocol conversion, and customizable local automation functionality to support substation automation applications. I/O with DNP communication is referenced in relation to D20 I/O options, and those I/O options will remain available for use with G500 products.
