Overview  
Compact FieldPoint  
The NI cFP-TC-12x and cFP-RTD-12x are versatile temperature input  
modules for Compact FieldPoint used to measure thermocouples,  
Compact FieldPoint is designed for industrial control applications that  
perform advanced embedded control, data logging, headless operation,  
millivolt-level voltages, thermistors, and 2-, 3-, and 4-wire RTDs. They are and Ethernet connectivity. Compact FieldPoint, a rugged, reliable NI platform,  
used in applications such as temperature chamber control, device testing, is designed for industrial and mobile environments with high shock,  
and process control. Thermocouples are low-cost, flexible temperature  
devices. RTD sensors are used in applications for acquiring temperatures  
with high accuracy. Two- and 3-wire RTDs work well for applications with  
short signal wires and low noise levels; 4-wire RTDs are well-suited for  
applications with long signal wires or high noise levels. All of these I/O  
modules include overranging and onboard diagnostics to ensure trouble-  
free installation and maintenance. The modules measure and linearize  
signals on board to return scaled values to your control or monitoring  
software. The cFP-TC-12x and cFP-RTD-12x modules have NIST-traceable  
calibration certificates (available upon request) to ensure accurate and  
reliable analog measurements.  
vibration, and temperature extremes.  
Isolation  
The cFP-TC-125 provides 250 Vrms common-mode voltage protection  
between channels, and all cFP-TC-12x and cFP-RTD-12x modules  
feature optical bank isolation with 2,300 Vrms of breakdown isolation.  
In addition, the cFP-TC-12x and cFP-RTD-12x offer double insulation for  
up to 250 Vrms of operational isolation. You can safely use Compact  
FieldPoint with the cFP-CB-1 or cFP-CB-3 connector block in applications  
where hazardous voltages are present.
