National Instruments 777318-124 Temperature Input Module for Compact FieldPoint
Part Number 777318-124 is the identifying part number for the National Instruments cFP-RTD-124 Temperature Input Module for Compact FieldPoint. The module supports measurement from two-wire, three-wire, and four-wire RTDs which means it is suitable for both low noise and high noise applications.
The 777318-124 mounts on a Compact FieldPoint backplane and its hot plug-and-play feature allows connection even when the backplane is powered on. The module has 8 input channels, all sharing a common ground and isolated from the other modules. Each channel contains a filter followed by an ADC for sampling. The ADC used is of Delta-sigma type and has a resolution of 16 bits. Likewise, the signal input bandwidth is 3 Hz while the channel update rate is once every second. Furthermore, the module requires 350 mW of power.
The temperature input signal range supported by the 777318-124 is –200 to 850 °C while the resistance input range is 0 to 400 Ω. When a resistance greater than 400 Ω is introduced, it throws an "Out of Range" error. It can linearize resistance values and return readings in units of temperature. Since it cannot automatically detect the type of RTD connected, the user must configure this manually on each channel. The RTD types are determined by material composition, TCR, and nominal resistance at 0 °C.
The 777318-124 weighs 3.7 oz and has two green status LEDs. The POWER indicator lights when the module is connected to the backplane and power is applied while the READY indicator lights once the configuration information is transferred to the module.The module is intended for indoor use only and must be mounted inside a sealed enclosure for outdoor use. The operating temperature range for the module is –40 to 70 °C while it can be stored at a wider temperature range of –55 to 100 °C.
The recommended relative humidity is 10 to 90%, noncondensing. The module conforms to electrical equipment safety standards EN 61010-1, IEC 61010-1, UL 3121-1, CAN/CSA C22.2 No. 1010.1 and EMC standards CE, C-Tick, and FCC Part 15 (Class A).
