National Instruments 781348-01 PXI Temperature Input Module

The part number 781348-01 from National Instruments is the identifying part number for the PXIe-4353 PXI Temperature Input Module. This PXI module is interfaced with a thermocouple for temperature sensing, providing high-resolution data crucial for scientific and industrial environments. It features 32 thermocouple channels with 2 auto zero channels and 8 cold junction compensation channels. It has a delta-sigma analog to digital converter (ADC) with a 24 bit resolution. Its maximum sampling rate is 90 S per second and a voltage measurement range of ±80 mV.

In terms of ambient temperature, the 781348-01 can operate at a temperature of 0 degrees Celsius to 55 degrees Celsius tested per IEC-60068-2-1 standard, and a storage temperature of -40 degrees Celsius to 71 degrees Celsius. Its operating relative humidity is 10% to 90%, noncondensing while its storage relative humidity is 5% to 95%, noncondensing tested per IEC-60068-2-56 standard. This module has a recommended warm up time of 15 minutes with a calibration interval time of one year. 

The 781348-01 module is designed to operate at the power requirement of 570 mA at +3.3 V and 200 mA at +12 V. Physically, this module has a compact structure with dimensions of 16 cm × 10 cm (6.3 × 3.9 in.) and weighs 139 g (4.9 oz).  It is equipped with an I/O connector 96-pin male DIN allowing easy integration into other digital devices. This module can be mounted at a maximum height of 2000 meters with a pollution degree of 2 and should be used indoors where non conductive pollution occurs.

It is designed to endure harsh working conditions with operating shocks of 30 g peak, half-sine, 11 ms pulse tested under IEC-60068-2-27 standard with random operating vibration of 5 Hz to 500 Hz, 0.3 grms and nonoperating vibration of 5 Hz to 500 Hz, 2.4 grms tested under the IEC-60068-2-64 standard. The 781348-01 Temperature Input Module is compatible with many safety standards including the IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1 standards making it suitable for measurement, control, and laboratory use. It is also EMC compatible prevents electrical interference, thus maintaining the efficiency and reliability of the module.
