National Instruments SCXI-1112 Thermocouple Input Module
The NI SCXI-1112 (Part Number: 776572-12) is a Direct-Connect Thermocouple Amplifier Module. This module is featured with 8 channels and is designed to amplify and filter signals generated from a thermocouple. On each of its eight channels, there is a 3-pole lowpass filter featured with a 2 Hz cutoff frequency capable of rejecting 60 Hz noise. In the NI SCXI-1112, each channel also has an amplifier with 100 fixed gain. With this module, the user can multiplex the inputs of the SCXI-1112 to a single output, driving a single DAQ device channel.
This module comes with an onboard voltage reference. Thus, the user can have it calibrated and auto-zeroed easily. The same auto-zeroing mechanism or circuitry can also be used for the removal of offset voltages. The NI SCXI-1112 is created for use with National Instruments MIO devices from the E series or with the SCXI-1200 modules. Several NI SCXI-1112 modules can also be multiplexed into a single channel, significantly increasing the number of analog inputs.
The SCXI-1112 is run using the NIDAQmx driver software driver which can be programmed using application development environments (ADEs) such as LabVIEW, LabWindows/CVI, ComponentWorks, or VirtualBench. Using any of the above ADEs greatly speeds up the development time.
The NI SCXI-1112 comes with an input signal range of ±100 mV. In normal powered on mode, the amplifier operates with an input impedance of >1 GΩ. However, in overload or powered off states the input impedance remains around 10 kΩ. This module has 2 Hz bandwidth. This module comes with a 96-pin male DIN C connector on its front panel and a 50-pin male ribbon cable connector is provided on the rear panel. The SCXI-1112 module requires 15 mA max power to operate normally.
The NI device measures 4.54 x 10.75 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 to 50 °C and –55 to 150 °C respectively, and a non-condensing relative humidity relative range of 5 to 90%.
SCXI-1112 End of Life Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
