National Instruments cFP-RTD-122 Temperature Input Module for Compact FieldPoint
The NI cFP-RTD-122 (part number 777318-122) is a flexible, hot-swapping temperature input module for Compact FieldPoint. The device has 8 single-ended input channels. The Compact FieldPoint platform measures temperature and resistance and is used in ovens, furnaces, HVAC systems, and environmental chambers. This module has 16-bit ADC resolution for precise measurements. The user can link straight to industrial sensors or units under test with the safety isolation function of this module. The cFP-RTD-122 temperature input module includes hot plug-and-play operation, simple configuration, and self-diagnostics. The device consumes 350 mW of power from the network.
The NI cFP-RTD-122 mounts onto a Compact FieldPoint backplane, which delivers functioning power to the module. When the user installs the cFP-RTD-122 module onto a powered backplane, it does not interrupt the procedure of the bank. This temperature input module has eight input channels, which have a common ground reference that is separated from other modules in the FieldPoint system. Every channel pulses a 0.25 mA excitation current out of the EX+ terminal. Then, the excitation current comes back through the COM terminal. The SENSE terminal then measures resistance and makes up for lead resistance mistakes. Next, every channel is filtered and sampled by a 16-bit analog-to-digital converter. The NI cFP-RTD-122 module can also be utilized to measure resistance in ohms. The user can complete measurements from RTDs of types that the module does not directly support, including 120 Ω nickel RTDs.
The cFP-RTD-122 weighs 3.7 oz. It has recommended operating and storage temperature ranges of -40 to 70°C and -55 to 85°C, respectively; a non-condensing relative humidity range of 10 to 90%; and random and sinusoidal operating vibrations of 5 grms and 5 g, respectively—all at a frequency range of 10 to 500 Hz. The temperature input module is designed to comply with the following electrical safety standards: IEC 61010-1, EN 61010-1, UL 3121-1, UL 61010C-1, and CAN/CSA C22.2 No. 1010.1.

National Instruments cFP-RTD-122 Frequently Asked Questions
Question: What type of indicators does the cFP-RTD-122 module have?
Answer: The Temperature Input Module has green POWER and READY status indicators.
Question: What are the power requirements for the NI cFP-RTD-122?
Answer: The NI cFP-RTD-122 requires 350 mW of power from the network module.
Question: What are the input signal ranges for the cFP-RTD-122?
Answer: The temperature input signal ranges are 73 to 1123 K, -200 to 850 °C, and -328 to 1562 °F. The resistance input signal ranges for the module are 0 to 400 Ω or 0 to 4,000 Ω.
Question: How often does the cFP-RTD-122 update its channels?
Answer: Each channel on the cFP-RTD-122 updates every 1.08 seconds.
Question: Can the cFP-RTD-122 be used with a LabVIEW application?
Answer: Yes. It is designed to work with LabVIEW, NI-DAQ, and FieldPoint Explorer for configuration, acquisition, and control.
Question: Can the cFP-RTD-122 measure sensors other than Pt100/Pt1000?
Answer: Yes—by using resistance mode, you can read unsupported RTDs (such as nickel sensors) and convert values in software.
