Function: Dual Channel/Dual Port Input Output Module
Series: Drive control
Availability: In Stock
Country of Manufacture: United States(USA)

IS200ADIIH1A is a Dual Channel/Dual Port Input Output Module manufactured and designed by General Electric. It functions as an auxiliary drive to ISBus interface board. An AcDc2000 drive is connected to an ISBus Local Area Network via the Auxiliary ISBusInterface board (ADII) (LAN). The ADIIboard is located on the backside of the AcDc2000 drive's first board carrier. The LNPL ribbon cable and COM1 wire connect the ADII board to the Drive Control/LAN Communications board (LDCC).

IS200ADIIH1A Functional Description

  • The ADII board receives power from the AcDc2000 drive's power supply board via the 2PL power cable. If the drive is turned off, the ADII board includes a bypass relay to maintain ISBus electrical continuity (no external bypass module is required).
  • The Innovation Series drive system applications signal map is used to generate the interface signal map. Many references and feedbacks are generic, and AcDc2000drive blockware must be developed to mimic the functionality of the Innovation Series drives. The ADII board connects the drive and controller via an integer variable map.
  • Scaling the integers to AcDc2000 units is required (given in the signal map definition). The interface is configured using either the LDCC board's local keypad or the GE Control System Toolbox (toolbox).


  • The ISBus has a single controller (drop 0) and a maximum of 31 nodes (1-31). The master sends out a stream of bytes containing the references to each ISBus node.
  • When the nodes receive the stream of bytes, they pass it on to the next node, replacing their reference data in the stream with their own feedback data. When the stream of bytes returns to the master, it contains feedback data from each node.
  • The ISBus frame rate can be set to 1, 2, 4, or 8 milliseconds (ms). A time delay of 200 seconds is required by the ADII board.

IS200ADIIH1A Connections

  • The ADII board interfaces to the ISBus through two RJ45 connectors, P2 (TX/OUT)and P3 (RX/IN). The userís cables are run into the drive package and directly to theADII board.The TX/OUT connector (P2) ties to the RX/IN connector (P3) of the next device onthe ISBus.
  • The RX/IN connector (P3) ties to the TX/OUT connector (P2) of theprevious device on the ISBus.

Application Data

There are no fuses or hardware jumpers on the ADII board. The ADII board includes LED indicators and testpoints for diagnostic and configuration purposes. Faults on the ISBus or ADIIboard will be displayed on the drive's display. The ADIIboard's testpoints are for manufacturing, diagnostic, and setup purposes.


  • The controller sends control bits and references for each drive on the ISBus in a single stream of bytes.
  • The first drive connected to the controller receives the stream of bytes, retrieves its command bits and references, and passes the stream of bytes to the next drive, which replaces the command bits and references with feedback bits and variables.
  • The controller receives the feedback bits and feedback variables from the drives when it receives the stream of bytes from the bus. The ISBus scan time can be set to 1, 2, 4, or 8 milliseconds. The number of devices on the bus limits these times.
