Key Benefits

 D20-D200
The D20 substation controller offers an industry leading design embedded with high value substation automation applications that provide cost savings, increased reliability, and improved operational efficiencies in your substations. The D20 device acts as the gateway to SCADA master stations for IEDs in the station, or for downstream substations or feeders. A large protocol library facilitates communication to most existing substation devices for improved visibility and remote control. The 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
The main chassis contains the central CPU(s) and communication ports and provides the data concentration, protocol conversion, and customizable local automation functionality. Available D20 main chassis include:
  • D20 main chassis - Single or 2 CPU options available
  • D200 main chassis - Up to 7 CPUs
    • Key Benefits
    A complete family of substation hardened I/O modules makes the D20 controller scalable to both large and small substations. A distributed architecture with both ring and star topologies allows for easy expandability and remote placement of I/O modules. The following I/O modules are available in a variety of models with I/O ranges up to 300VDC.
  • D20S - 64 channel status input module
  • D20A - 32 channel DC Analog input module
  • D20K - 32 channel control output module
  • D20KI - 8 external interposer relay pairs module
  • D20C - 16 status input, 8 control output, optional 16 DC analog inputs or 8 analog inputs and 8 analog outputs
  • D20AC - 15 channel direct AC input, 1 DC analog input module
    • Key Benefits
    The DNP I/O modules are data collection and control devices that combine the DNP 3.0 communications protocol with our existing industry proven and robust line of I/O modules. The DNP I/O modules implement the industry standard DNP 3.0 (Level 2) slave protocol over a single RS485 interface to provide expandable I/O functionality for the D400, D25 and iBox product lines, as well as third-party products.
    The following DNP I/O modules are available:
  • DNPIO-DI (D20S)
  • DNPIO-DCAI (D20A)
  • DNPIO-CO (D20K)
  • DNPIO-C (D20C) – available soon
    • Note: The D20AC (AC analog) module is not available with the DNP communication option.
