The IS220PAICH1A is an analog I/0 Pack developed under the GE Mark Vl series. Simplex and triple Module redundancy (TMR) MarkV control systems can be used in small applications and large integrated systems, with control ranging from a single module to multiple distributed modules. The system’s throughput allows the operation of up to nine I/O boards of a 21-slot VME rack, including data voting, in 40 milliseconds. In an approach called software Implementation Fault tolerance, input votes in software (SIFT). Each control module’s VCMI board receives input from the control module backplane and other modules through its own IONet.
