Description
The Part Number 777687-22 refers to a specialized component categorized under SCXI & Legacy, specifically the SCXI-1322 model. This part is designed to be compatible with the SCXI-1122 module, and it is intended for mounting at the front of the SCXI module. One of its standout features is the onboard sensor for cold junction compensation, which plays a critical role in its operation.
It is primarily used in measurement applications that require isolation, making it a versatile component in various testing and measurement setups. The SCXI-1322 is equipped with 48 screw terminals to facilitate connections. Specifically, it provides 16 pairs for inputs and 7 pairs for module excitation channels, which are crucial for its functionality.
Furthermore, the terminals for excitation are designated as VEX/SENSE+ and VEX/SENSE-, with the factory default setting including resistors R3 and R4 loaded for VEX+ and VEX- terminals. However, it also offers remote sensing capability, which can be enabled by removing resistors R3 and R4, providing flexibility in its application.
Despite its obsolete status, it has been announced that the component is still available for purchase and repairs through Apex Waves. This ensures that users of this specific model can still obtain and maintain their components as needed, keeping their systems operational.
