National Instruments 785189-01 C Series Temperature Input Module.

The part number 785189-01 from National Instruments is the identifying part number for the NI-9226 C Series Temperature Input Module. This module features 8 analog input channels with a delta-sigma analog to digital converter of resolution 24 bits. It has the capability of measuring temperatures of range -200 degrees Celsius to 850 degrees Celsius and resistance of range 0 Ω to 4,000 Ω. Its conversion time on a high-resolution mode is 200 ms per channel. This mode is ideal for applications that require precise and detailed temperature readings. while on the other hand, for the high-speed mode, its conversion time is 2.5 ms per channel providing 20 ms total for all channels.

The C Series Temperature Input Module is designed to operate at ideal temperature readings of -40 degrees Celsius to 70 degrees Celsius and a storage temperature of -40 degrees Celsius to 85 degrees Celsius. Its operating relative humidity range is 10% RH to 90% RH, non-condensing while its storage relative humidity range is 5% RH to 95% RH, non-condensing. This module has an ingress protection of IP40 hence making it resistant to dust and moisture. It is required to mount this module at a maximum height of 5000 meters and has a pollution degree of 2.

To operate this module, it draws power from the PXI chassis with a power consumption of 463 mW in active mode and 90 µW in sleep mode. Its maximum thermal power dissipation is 1.2 W in active mode and 0.76 W in sleep mode. In terms of weight, this PXI module offers different weights, with a spring terminal black connector it weighs 156 g (5.5 oz), with a spring terminal orange connector it weighs 161 g (5.7 oz) and with a DSUB it weighs 143 g (5.04 oz).

The 785189-01 module is manufactured to operate under harsh working conditions with operating shocks of 30 g, 11 ms half-sine; 50 g, 3 ms half-sine; 18 shocks at 6 orientations and operating random vibration of 5 g RMS, 10 Hz to 500 Hz with sinusoidal vibration of 5 g, 10 Hz to 500 Hz.
