Description
D20ME II Main ProcessorThe D20ME II, the fifth generation of D20/D200 processors, builds on the increased memory,performance and communication port speed introduced with the D20ME. Where the D20MEsupports up to eight RS-232 serial ports (one of which is reserved for the maintenance port), theD20ME II supports:• Seven serial ports, each of which can be configured as either RS-485 or RS-232, and• One RS-232 maintenance port.Each D20ME II RS-485 port can communicate with up to 32 devices and operate over distances upto 4000 feet, without the use of repeaters (see note below). The D20ME II is backwards compatiblewith VME and non-VME versions of the D20 chassis, and with the D200 chassis.
The D20EME allows VME-based D20 and D200 systems to be connected directly to any 10 MBEthernet-based network. Available configurations of the D20EME module include:• Ethernet only• Memory only• Ethernet and MemoryFor more information, see section 2.3, Ethernet/Memory Expansion (EME) Kit.New D20/D200 I/O PeripheralsSeveral new I/O peripherals have been added to the D20/D200 product family.D20AC, AC Analog Input PeripheralThe D20AC, AC analog input peripheral provides AC analog computing and monitoring. It hasthe following features:• Up to 132 analog values and 18 accumulator values• Direct AC analog inputs from current and voltage transformers for up to three 3-phasecircuits, eliminating the need for transducers and/or metering IEDs• Integrated key substation functions such as metering, analog processing and power qualitymeasurement• 3-element and 1-element (balanced system) metering• Meter calculations include kW, kVArs, kVA, power factor, frequency, kWh, kVARh, kVAhand symmetrical components.• Power quality data: %THD (total harmonic distortion), 21For more information, see section 2.4.11 , D20AC, AC Analog Input Peripheral
