National Instruments 779592-01 Temperature Input Module

Part number 779592-01 from National Instruments is the identifying number for the NI-9217 Temperature Input Module. This reliable C Series module is compatible with CompactDAQ and CompactRIO platforms and comes equipped with four analog input channels. The 779592-01 has a Delta-sigma ADC with 24 bits of resolution and features two distinct conversion time modes, high-resolution and high-speed. 

In high-resolution mode, the 779592-01 operates at a conversion rate of 200 ms per channel (a total of 800 ms for all channels). Alternatively, the swift conversions of high-speed mode equate to 2.5 ms per channel, (a total duration 10 ms for all channels). The noise levels for the 779592-01 are dependent on which mode is used, as it has a level of 0.003 °C for high-resolution mode and a level of 0.02 °C for high-speed mode. 

When the 779592-01 is operating in high-resolution mode, the input bandwidth is 3.3 Hz. The power requirements vary between active mode (maximum 350 mW) and sleep mode (maximum 1 mW), allowing the input module to facilitate precise measurements. The 779592-01 boasts a temperature measurement range that spans from -200 °C to 850 °C (-328 °F to 1,562 °F), allowing for a diverse range of measurements within various testing scenarios. Its common mode range accommodates ±250 Vrms from COM-to-earth ground and 50 mV from Channel-to-COM.

To ensure efficient and secure connectivity, the 779592-01 is designed for screw-terminal wiring capabilities, with single wires in each screw terminal. However, two wires could be used per screw terminal if a 2-wire ferrule is used. The wire gauge range spans from 0.05 mm2 to 1.5 mm2 (30 AWG to 14 AWG) for copper conductors.
