About the IS220PTCCH1A
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
IS220PTCCH1A PTCC Thermocouple Input Module Diagnostics
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.
