About the IS420ESWBH3A
As with any General Electric printed circuit board product offering made available to our extended new and reconditioned inventory here, this IS420ESWBH3A IONET Switch Board belongs to a specific product series; the Mark VIe Turbine Control System Series in particular. This IS420ESWBH3A printed circuit board or PCB for short's greater Mark VIE Turbine Control System Series is something of a self-explanatory GE Mark product series, given the fact that it possesses specific applications across a range of different products including various styles of Mark VIe Series-compatible wind, steam, and gas turbine automated drive assemblies. With this being true, this IS420ESWBH3A IONET Switch Board device's greater Mark VIe Turbine Control System Series can additionally be identified as a desirable GE Mark Series given the fact that it is one of the lastly-developed GE product series to make use of the patented Speedtronic control system technology first seen alongside the rollout of the initial Mark I Series in the mid to later 1960s.
Hardware Tips and Specifications
Industrial Ethernet Switch IS420ESWBH3A is part of the Mark VIe Safety Control System designed by General Electric. This switch does not have any fiber ports but has sixteen copper ports, the copper ports are 10/100Base-TX RJ45 ports. The primary operation of the switch is to perform as a level one Ethernet switch which will center on the capability to buffer multi-cast and broadcast packets. There should be enough space to allow for the buffer of one packet per port; if multiple incoming streams are being sent to the switch, it can only accept one incoming stream out of the multiple streams and will buffer the remaining streams for later transmission. Given this IS420ESWBH3A product's General Electric original manufacture, it has been attributed with a standard functional product number designed to highlight a number of critical IS420ESWBH3A Board details in a series of consecutive functional naming elements. For instance, the IS420ESWBH3A functional product number begins with a dual-functioning initial naming segment in the IS420 series tag delegating this IS420ESWBH3A Mark VIe Series product's special modular Mark VIe Series assembly version as well as its domestic location of original GE manufacture. Some of the other relevant hardware details that can be discovered through analysis of functional product number include this IS420ESWBH3A PCB's:
- ESWB product acronym
- Conformal PCB coating style
- Group three Mark VIe Series product grouping
- A-rated primary functional product revision
There are LED indicators on the IS420ESWBH3A switch. There is a power LED and the remaining LEDs are activity and link functions. When the link LED is solid yellow it indicates that a 10 MB link is being used and when solid green a 100 MB link is being used, and no LED light indicates that there is no link. The colors for the activity LED are also green and yellow but they will flash, when the LED flashes green it indicates that the activity is at full duplex and when flashing yellow the activity is at half duplex. The IS420ESWBH3A switch can be mounted in a variety of ways, the switch can be DIN-rail mounted in a parallel or perpendicular application and also has the possibility to be panel mounted if needed. Please note that when the switch is DIN-rail mounted there are different clips needed which are the 259B2451BVP1 and 259B2451BVP4 clips. According one again to one of the various General Electric instructional manual materials attached above, this IS420ESWBH3A device's H3 Mark VIe Series product grouping indicates the fact that this IS420ESWBH3A board is actually the only Mark VIe ESWB Board group version to not make use of a single style of Mark VIe Series fiber port component in its special modular Mark VIe Series assembly.
