Description
The SCXI-1322 Temperature Sensor Terminal Block, part number 185697A-01 (777687-22), falls under the SCXI & Legacy category. This model is specifically designed for compatibility with the SCXI-1122 module. It features an onboard sensor dedicated to cold junction compensation, enhancing its performance in temperature sensing applications.
The terminal block boasts 48 screw terminals, allowing for robust and secure connections. It facilitates 16 pairs of input connections that link directly to the SCXI-1122 inputs, ensuring a seamless integration with the module. Additionally, there are 7 pairs of screw terminals dedicated to module excitation channels, labeled as VEX/SENSE+ and VEX/SENSE-, providing flexibility in sensor excitation and sensing configurations.
By default, the terminal block is equipped with resistors R3 and R4 loaded for VEX+ and VEX- to accommodate standard operational conditions. However, for applications involving heavy load conditions, an adjustment can be made by removing resistors R3 and R4. This adjustment enables remote sensing, offering an adaptive solution for various operational demands.
It is important to note that the SCXI-1322 has been announced as obsolete by National Instruments. Despite this status, it remains available for purchase and repairs through Apex Waves, ensuring continued support for users relying on this essential component in their temperature sensing setups.
