About the IS220PTCCH1A
The IS220PTCCH1A is a thermocouple input manufactured by General Electric for function specifically within the Mark VI/Mark VIe systems. These systems were some of the later Speedtronic controls system technology systems developed and released by General Electric for the management and control of gas, hydro and steam industrial turbine systems. The Mark VIe Series that this IS220PTCCH1A Thermocouple Input Module belongs to must be considered a decently-strong step up from the Mark V Turbine Control System Series even, given the fact that the Mark V Series has a more-restricted set of specific applications in steam and gas turbine automated drive assembly settings alone. While this is true, this IS220PTCCH1A device's greater Mark V Turbine Control System Series is still definable as one of the lastly-developed GE Mark product series to make use of the patented Speedtronic control system technology as mentioned above, while increases its overall market desirability by itself.
Hardware Tips and Specifications
This pack has an internally placed BPPx processor board as well as an acquisition board that is used for thermocouple input functions. Before even considering any ultimate purchase decision on this IS220PTCCH1A device, it is crucial to understand the fact that this IS220PTCCH1A device is actually not the originally-developed product of its specific Mark V Series intended functional role, as that would in fact be the IS220PTCCH1 parent Thermocouple Input Module noticeably not adopting this IS220PTCCH1A device's sole A-rated functional product revision. The IS220PTCCH1A can be used in simplex, duplex, and triple modular redundant applications. This board can support E, J, K, S, and T standard thermocouples as well as mV inputs with a span of -8 to 45 mV. E, J, K, S, and T thermocouples can be either grounded or un-grounded and can be located up to 984 feet from the turbine I/O panel. Cable resistance must be kept to a maximum 450 Ω. The number of packs used dictate the following:
- Qty 1 IS220PTCCH1A - 12 Thermocouple Inputs
- Qty 2 IS220PTCCH1A - 24 Thermocouple Inputs
- Qty 3 IS220PTCCH1A - Used in TMR Configurations
The IS220PTCCH1A offers a maximum software error/conformity error of .25 degrees Fahrenheit. Common mode voltage is +/- 5 volts with AC common-mode rejection of 100dB @50/60Hz. Common mode rejection includes filtering for both hardware and software. The unit also includes normal mode rejection of 250 mV RMS @ 50/60 Hz (+/-5%) and high/low hardware and software limit checks. The unit is designed for operation in ambient conditions from -22 to +149 degrees Fahrenheit. The IS220PTCCH1A can perform multiple self-diagnostics including power-up self-tests of flash memory, RAM, processor board hardware, and Ethernet ports. It also offers continuous monitoring of its internal power supplies to ensure proper functions. Additional information about the IS220PTCCH1A, including important handling and installation instructions and warnings, can be found in GE product manuals and guides. Generally, this IS220PTCCH1A device's voltage suppression and limitation strategy involves its normal Mark V Series assembly's acceptance of various series-standardized limiting hardware component such as various styles of capacitors, resistors, transistors, diodes, and specialized integrated circuits.
