National Instruments 777687-13 Terminal Block
National Instruments part number 777687-13 is an identifying part number for the SCXI-1313, a High-Voltage Attenuator Terminal Block with 18 Screw Terminals and 1.91 to 0.65 V Cold-junction sensor Output. Each channel on the 777687-13 features a precision 100:1 resistive voltage divider, enabling the measurement of voltages up to 300 VRMS or ±300 VDC when used with the SCXI-1125. For low-voltage measurements, the dividers can be bypassed individually. One pair of 18 screw terminals connects to the SCXI-1125 module chassis ground, while the remaining eight pairs connect signals to the eight analog inputs.
This Terminal Block is managed using the NIDAQmx driver software, which seamlessly integrates with software packages or application development environments like LabVIEW or LabWindows/CVI. Configuration of the device can be easily accomplished using the Measurement & Automation Explorer (MAX) tool. Users have the flexibility to control the attenuator on the 777687-13 by adjusting the standard configuration settings within Measurement & Automation Explorer. Alternatively, they can modify the input limit ranges directly within their application. When using virtual channels, the input limits configured in the virtual channel configurator are applied to correctly designate the attenuation circuitry.
Additionally, this Terminal Block features a built-in temperature sensor that provides voltage outputs ranging from 1.91 to 0.65 V within a temperature range of 0 to 50 °C. In LabVIEW, users can utilize the "Convert Thermistor Reading" function to interpret these readings accurately. It's recommended to gather multiple samples to achieve the highest level of precision, especially in noisy environments where more samples are necessary for accuracy assurance. Electrical safety standards compliance for the 777687-13 includes adherence to IEC 61010-1, UL 3111-1, and CAN/CSA C22.2 No. 1010.1.
