About the IS420UCPAH2A
The IS420UCPAH2A module is the second of the two Controller Programs with Integral I/Os as part of the Mark VIe Turbine Control System Series produced by General Electric. The Mark VIe Series, as you have have been able to guess based off of its full extended series name alone, has specific turbine-based applications across a range of gas, steam, and even wind options. With this being true, the Mark VIe Turbine Control System Series is also describable as desirable on the figurative automated industrial marketplace as it is one of GE's final-developed GE Mark product series to make use of their patented Speedtronic control system technology which was first released alongside the rollout of the Mark I in the mid to later 1960s. This IS420UCPAH2A device is not the originally-developed product of its specific Mark VIe or Mark VIeS Series functionality; that would in fact be the IS420UCPAH2 parent Integral I/O Controller Module not utilizing this IS420UCPAH2A device's sole A-rated functional product revision.
Hardware Tips and Specifications
This controller is nearly the same as the previous UCPA controller save for the IS400WEXPH1A expansion I/O board which allows for additional I/O capabilities. The additional I/O capabilities on this controller are four additional DIOs, which totals eight; six additional AIs, also totaling eight, and two analog outputs. Same as the previous controller the input-output points on this controller also have the capability to be configured on a per-point basis. After installation, the IS420UCPAH2A controller is mounted directly on a sheet metal panel and is contained within a single module. When operating properly the controller will run on a nominal power supply of twelve volts of direct current, within the range of nine to sixteen volts of direct current. The power input will be powered by a Class II protection level. When wiring the controller input terminals please ensure that they are no longer than ninety-eight feet in length. According to this IS420UCPAH2A device's originally-devised Mark VIe Series instructional manual materials, this IS420UCPAH2A device is actually a modular assembly composed out of three separate components. These specific components include the:
- IS400BPPCH2A Processor Board
- IS400STWCH1A Input/Output Board
- IS400WEXPH1A Input/Output Expansion Board
The WEXP-abbreviated Board in this IS420UCPAH2A device's special modular Mark VIeS or VIe Series assembly provides a series of unique I/Os to this IS420UCPAH2A product, including various analog inputs, analog outputs, as well as four total DIOs, as delegated in the IS420UCPAH2A instructional manuals and datasheet attached in our manuals section below for your convenience. The IS420UCPAH2A controller has several LEDs, DIO1-8, Pulse 1 and 2, and an attention LED. The DIO and Pulse LEDs will be solid yellow but the attention LED will be red and green with multiple flash codes. There are both green and red ATTN LED flash codes, some of which are as follows, a red four hertz LED at fifty percent indicating that the diagnostic alarm is active, a red one hertz LED at fifty percent which indicates that no firmware is available, and a green one/two hertz LED at fifty percent indicating that the component has completed power up. All information needed to properly operate the IS420UCPAH2A controller is located in the GEI-10071 Mark VIe Controller UCPA Instruction Guide.
