Description
The Part Number 777687-22 refers to a specific product within the SCXI & Legacy category, more specifically, the model SCXI-1322. This product is described as a Temperature Sensor Terminal Block, designed to be compatible with the SCXI-1122 module. Its primary function includes onboard sensor technology for cold junction compensation, enhancing its utility and efficiency in temperature measurement applications.
The SCXI-1322 boasts 48 screw terminals, providing ample connection points for various inputs and outputs. Specifically, it includes 16 pairs for SCXI-1122 inputs and 7 pairs for module excitation channels, offering considerable flexibility in connecting multiple sensors and devices. Additionally, the terminals VEX/SENSE+ and VEX/SENSE- are significant features, with the factory default settings including R3 and R4 loaded for VEX+ and VEX- usage. However, it’s important to note that remote sensing capabilities are available, but this requires modification by removing R3 and R4.
Another critical feature of the SCXI-1322 is its voltage excitation channel, which is one and is provided by the SCXI-1122. This adds to the versatility and functionality of the terminal block, allowing for precise and accurate temperature measurements.
Despite its advanced features and capabilities, the SCXI-1322 has been announced as obsolete by National Instruments. However, it remains available at Apex Waves, providing an opportunity for users requiring this specific model for their applications. This availability ensures that existing systems using the SCXI-1322 can continue operating without the need for immediate upgrades or replacements.
