About the IS420YDIAS1B
This IS420YDIAS1B printed circuit board product offering from General Electric was, as mentioned in the brief supplied product description blurb, was originally designed and produced specifically for placement in the Mark VIe Turbine Control System Series or the Mark VIeS Series. The Mark VIe Series that this IS420YDIAS1B device belong to has a series of specific applications in General Electric-compatible control and management systems of steam, wind, and gas turbine automated drive assemblies; a marked improvement on the previous Mark V Turbine Control System Series' more restricted gas and steam applications. The Mark VIe or Mark VIeS Series that this IS420YDIAS1B modular assembly product belongs to is additionally desirable on the greater automated industrial marketplace as a function of its existence as one of the final-developed General Electric Mark Series to make use of the brand's patented Speedtronic control system technology first seen with the previous rollout of the Mark I Series in the mid to later 1960s.
Hardware Tips and Specifications
This IS420YDIAS1B product offering from the Mark VIe Series is not your typical General Electric Mark Series printed circuit board component; as partially evidenced by its IS420YDIAS1B functional product number's suggestion of a special assembly version involving the atypical S-rated style of PCB product protection. Ultimately, this manifests in this IS420YDIAS1B device's existence as a plastic-encased modular component involving a front faceplate adorned with various diagnostic LED indicators all accompanied by their own factory-printed nomenclature labels detailing various diagnostic values. On the opposite side of this IS420YDIAS1B product offering's cubic rectangular body exist three total ports for various important Mark VIe Series interfacing processes. These ports include two Ethernet-style ports meant for signal transmission, as well as a singular female port existing near this IS420YDIAS1B product's two installation-minded screw standoffs. This female port likely exists as a power source to this IS420YDIAS1B Modular Assembly. This IS420YDIAS1B device is actually not the firstly-developed product of its specific Mark VIe or Mark VIeS Series functionality; that would be the IS420YDIAS1 parent Discrete Input I/O Pack missing this IS420YDIAS1B product's sole B-rated functional product revision.
The above-included information on this IS420YDIAS1B personalized product page here is primarily reminiscent of a visual analysis of the IS420YDIAS1B Modular Assembly itself, given the low general availability of Mark VIe or Mark VIe Turbine Control System Series instructional manual materials online. This lack of original instructional documentation is also deemed responsible for the adoption of the IS420YDIAS1B functional product number as a primary source of IS420YDIAS1B Module hardware information. The IS420YDIAS1B functional product number indirectly describes numerous IS420YDIAS1B Board details in a series of consecutive functional naming components. For instance, this IS420YDIAS1B product number actually begins with a dually-responsible naming component in the IS420 series tag indirectly delegating the IS420YDIAS1B module's special modular Mark VIe Series assembly version as well as its domestic original location of manufacture. This dual-functional initial tag is followed in the IS420YDIAS1B functional product number by an instance of the YDIA functional product abbreviation, which is itself followed by the S1 series grouping tag; another dual-functional segment. The S1 series grouping tag describes this Mark VIe Series assembly's S style of PCB surface coating as well as its B-rated singular functional product revision. The final trailing B digit in the IS420YDIAS1B functional product number reveals this IS420YDIAS1B device's B-rated functional product revision.
