IS220PTCCH1A

About the IS220PTCCH1A

• Model Name: IS220PTCCH1A.
• Type: Thermocouple Input Module (PTCC).
• Originality: Not the originally-developed product for its specific Mark V Series functional role; it is a revision (A-rated) of the IS220PTCCH1 parent module.
• Internal Components:
  • Internally placed BPPx processor board.
  • Acquisition board for thermocouple input functions.
• Application Compatibility: Can be used in simplex, duplex, and triple modular redundant (TMR) applications.

Thermocouple & Input Support

• Supported Thermocouple Types: E, J, K, S, and T standard thermocouples.
• mV Inputs: Supports mV inputs with a span of -8 to 45 mV.
• Thermocouple Grounding: E, J, K, S, and T thermocouples can be either grounded or un-grounded.
• Distance from Turbine I/O Panel: Can be located up to 984 feet (300 meters) from the turbine I/O panel.
• Cable Resistance: Cable resistance must be kept to a maximum of 450 Ω.
• Input Quantity based on Pack Quantity:
  • Qty 1 IS220PTCCH1A: 12 Thermocouple Inputs.
  • Qty 2 IS220PTCCH1A: 24 Thermocouple Inputs.
  • Qty 3 IS220PTCCH1A: Used in TMR Configurations.

Diagnostics and Performance

• Maximum Software Error/Conformity Error: 0.25 degrees Fahrenheit.
• Common Mode Voltage: ±5 volts.
• AC Common-Mode Rejection: 100 dB @ 50/60Hz (includes hardware and software filtering).
• Normal Mode Rejection: 250 mV RMS @ 50/60 Hz (±5%).
• Limit Checks: High/low hardware and software limit checks.
• Operating Ambient Conditions: -22º to +149º Fahrenheit (-30º to +65º Celsius).
• Self-Diagnostics: Performs multiple self-diagnostics, including:
  • Power-up self-tests of flash memory, RAM, processor board hardware, and Ethernet ports.
  • Continuous monitoring of internal power supplies.
• Voltage Suppression & Limitation: Utilizes series-standardized limiting hardware components (capacitors, resistors, transistors, diodes, specialized integrated circuits).
