National Instruments 776572-12 Thermocouple Input Module 

National Instruments part number 776572-12 is an identifying part number for the SCXI-1112, a Thermocouple Input Module with 8 differential input channels and a maximum working voltage of ±10 V. The NI 776572-12 is a Direct-Connect Thermocouple Amplifier Module with 8 channels. It is designed to amplify and filter signals from thermocouples. Each channel includes a 3-pole low-pass filter with a 2 Hz cutoff frequency to reject 60 Hz noise and an amplifier with a fixed gain of 100. This module allows multiplexing of its inputs to a single output, driving a single DAQ device channel. 

The module has an input signal range of ±100 mV and an input impedance of >1 GΩ in normal operation, dropping to around 10 kΩ in overload or powered-off states. Moreover, It features a 96-pin male DIN C connector on the front panel and a 50-pin male ribbon cable connector on the rear panel. The Part number 776572-12 requires a maximum power of 15 mA for normal operation. This module features an onboard voltage reference, allowing easy calibration and auto-zeroing. The same auto-zeroing mechanism can be used to remove offset voltages. The NI 776572-12 is designed for use with National Instruments MIO devices from the E series or with SCXI-1200 modules. Multiple NI SCXI-1112 modules can be multiplexed into a single channel, significantly increasing the number of analog inputs. 

Additionally, this module operates with the NIDAQmx driver software, which can be programmed using application development environments (ADEs) like LabVIEW, LabWindows/CVI, ComponentWorks, or VirtualBench. Using any of these ADEs can greatly reduce development time. This NI device measures 4.54 x 10.75 inches. It has a recommended operating temperature range of 0 to 50 °C and a storage temperature range of –55 to 150 °C. The non-condensing relative humidity range is 5 to 90%. National Instruments has announced End of Life Status for the 776572-12, however, it is still available for purchase on the Apex Waves Website.
