About the IS220PTURH1A
The IS220PTURH1A is a printed circuit board modular assembly component created by GE for their Mark VI system. The Mark VI is one of the final Speedtronic systems for gas/steam turbine management that was released by GE, with the Speedtronic control system technology first formally being recognized with the advent of the previous Mark I Series in the mid to later 1960s. This IS220PTURH1A device's Mark VI Series is not quite as far-reaching in its specific intended possible applications as the later Mark VIe Turbine Control System Series is, given the fact that the Mark VIe Series has additional settings in wind turbine automated assemblies and control systems. Given that this IS220PTURH1A product's greater Mark VI Series is one of the final-developed General Electric Speedtronic product series, it is still able to attract some niche demand on the always-evolving automated industrial marketplace. This IS220PTURH1A device is actually not the original product of its specific Mark VI Series functionality produced by General Electric; that would be the IS220PTURH1A Turbine Specific Primary Trip Module notably not utilizing this IS220PTURH1A product's sole A-rated functional product revision.
Hardware Tips and Specifications
The IS220PTURH1A is a Primary Turbine Specific Primary Trip pack. This component provides an electrical interface between a turbine control terminal board and either one or two Ethernet networks. Outputs from this pack occur through a DC-62 pin connector that connects to an associated terminal board. The IS220PTURH1A is built with a black outside casing with openings for air circulation. The front of this case has multiple LED indicators, as well as an IR (infrared port.) This port is not used in this pack. Inside this casing, there is a processor board, a second board specific to turbine control, and an analog acquisition auxiliary board. The pack mounts to the TTURH1C terminal board. The processor board has two 10/100 Ethernet ports, flash memory, and RAM, a read-only chip for identification, an internal temperature sensor, and a reset circuit. The style of terminal block that has been afforded to this IS220PTURH1A product's norma Mark VI Series assembly is the Euro-style terminal block; most likely the most common General Electric terminal block style available across the entirety of their Mark Series product suite.
The IS220PTURH1A allows for Auto-reconfiguration, which will automatically download from the controller to the I/O pack. The reconfiguration includes baseload, bootload, firmware, and parameters. Auto-reconfiguration must be enabled for this to occur. This is enabled or disabled in the Toolbox ST application through the Component Editor. The IS220PTURH1A has an interface with four passive, magnetic speed inputs. Circuit sensitivity can allow detection of 2-RPM turning gear speed to determine if the turbine has dropped to zero speed (turbine has stopped.) The median speed signal on the pack is used for speed control and for primary overspeed trip signal. Consult manuals or datasheets from the manufacturer if you need more information. This IS220PTURH1A product from GE"s Mark Series suite is, as these products often are, a highly voltage-sensitive model of printed circuit board. With this being the case, General Electric is sure to list many of this IS220PTURH1A device's various electrical characteristics in a chart form for your convenience of research.
