About the IS420YAICS1B
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, as hinted at through its full extended series name, has specific applications in the management and control systems of popular, General Electric-compatible wind, gas, and steam turbines; an upgrade on the heavily relied-upon Mark V Series as the Mark V Series only possesses specific applications in gas and steam turbine assemblies specifically. With this being the truth, the Mark VIe Series that this IS420YAICS1B product offering belongs to is additionally considered a desirable General Electric Mark product series as it is one of the final-developed General Electric Mark product series to make use of the patented Speedtronic control system technology first seen with the rollout of the Mark I Series in the mid to later 1960s.
Hardware Tips and Specifications
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. This pack can handle up to ten analog inputs, two of which can be configured as ±1 mA or 4-20 mA current inputs while the remaining eight are ±5 V or ±10 V inputs, or 4-20 mA current loop inputs. This pack can send and receive data through dual RJ45 Ethernet connectors. As detailed in the IS420YAICS1B instructional manual attached above in our manuals tab for your convenience, This IS420YAICS1B I/O Pack is made up of two components; one common processor board and one data acquisition board. This IS420YAICS1B product offering's 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. This IS420YAICS1B device is actually not the originally-developed product of its specific Mark VIe Turbine Control System Series functionality; that would have to be considered the IS420YAICS1 parent Analog I/O Pack notably not making use of this IS420YAICS1B product offering's singular significant B-rated functional product revision.
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. 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 and RAM memory, most of the processor board hardware, and 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.
