About the IS420YAICS1B

Greater Mark Product Series Information

This IS420YAICS1B modular assembly product offering from General Electric was originally devised and produced with a specific functional role of an Analog I/O Pack in mind, for placement in the greater Mark VIe Turbine Control System Series. The Mark VIe Series that this IS420YAICS1B modular assembly belongs to has:

• specific applications in the management and control systems of popular, General Electric-compatible wind, gas, and steam turbines
  • the Mark V Series only possesses specific applications in gas and steam turbine assemblies specifically
• a status as a desirable General Electric Mark product series
  • one of the final-developed General Electric Mark product series to exhibiting the patented Speedtronic control system technology first seen with the rollout of the Mark I Series

IS420YAICS1B I/O Pack Intended Functionality

The Analog I/O Pack IS420YAICS1B is part of the Mark VIe Series produced by General Electric. This I/O pack can:

• interface between up to two Ethernet networks and a terminal analog I/O board
• handle up to ten analog inputs
  • two of which can be configured as ±1 mA or 4-20 mA current input
  • the remaining eight are ±5 V or ±10 V inputs, or 4-20 mA current loop inputs
• send and receive data through dual RJ45 Ethernet connectors

Additional IS420YAICS1B Device Hardware Information

This IS420YAICS1B I/O Pack is made up of two components;

• one common processor board
• one data acquisition board
  • diagnostic fault detection processes are completely handled solely through its data acquisition board

The associated terminal boards adopted in the robustly-supported modular assembly of the YAIC Analog I/O Pack here are the TBAISIC and STAIS2A terminal boards, which are both also considered component members of the greater Mark VIe Turbine Control System Series. While a variety of the units in the Mark VIe Series can be used in dual, TMR, or simplex redundancy applications, the IS420YAICS1B I/O pack can only be used in TMR or simplex applications, please note that when using this pack in a TMR redundant application three I/O packs will be used while only one I/O pack will be used in a simplex redundant application.

IS420YAICS1B Device Diagnostic Detail

Another vital note is that all of the I/O packs within the TMR set must be in the same hardware form. There is another version of the YAIC I/O pack that is labeled as the IS420YAICS1A pack, please note that the pack versions cannot be mixed on the same T-type terminal board. The IS420YAICS1B I/O pack can perform several self-diagnostic tests, some of which are:

• a power-up self-test that will check the:
  • flash memory
  • RAM memory
  • most of the processor board hardware
  • the Ethernet ports on the pack

This pack can also continuously monitor the internal power supplies to ensure correct operation. As detailed in the IS420YAICS1B functional product number, this IS420YAICS1B device exists within the very first grouping of Mark VIe Turbine Control System Series products.
