IS220PTCCH1B Thermocouple Input Module
The IS220PTCCH1B Thermocouple Input Module accepts 12 signals at mV levels from the thermocouples wired to the terminal board. The analog input section consists of six differential multiplexers, a main multiplexer, and a 16-bit analog to digital converter that sends he digital data to the adjacent processor board. Each input has hardware and firmware filters, and the converter samples at up to 120Hz.
Type E, J, K, S, and T thermocouples can be used with PTCCH1, and they can be grounded or ungrounded. Type E, J, K, S, T, B, N and R thermocouples can be used with PTCCH2, and they can be grounded or ungrounded. Thermocouples can be located up to 300 meters (984 feet) from the turbine I/O panel with a maximum two-way cable resistance of 450 Ω.
Linearization for individual thermocouple types is performed in software by the I/O pack board. A thermocouple, which is determined to be out of the hardware limits, is removed from the scanned inputs in order to prevent adverse affects on other input channels. If two packs are used, and both Cold Junction (CJ) devices are within the configurable limits, then the average of the two is used for CJ compensation.
