National Instruments SCXI-1163R

The National Instruments SCXI-1163R Relay Switch Module (Part Number: 776572-63R) features 32 Form A (normally open), optically isolated solid-state relays organized into eight banks of four, each sharing a common pole. This module is designed to effectively switch high-voltage loads of up to 240 VAC/VDC and a maximum current of 200 mA, making it suitable for various industrial and laboratory applications. The SCXI-1163R is capable of controlling AC and DC voltage and power signals to field instruments. Complementary accessories include the SCXI-1326 terminal block, PXI-4021 switch controller, and PCI-4021 switch controller, along with various adapters and cable assemblies. The module connects via a 48-pin DIN C male I/O connector.

Programming is facilitated through multiple software options including LabVIEW, LabWindows, NI-DAQ, or register-level programming, allowing for flexible and efficient application development. While using LabVIEW or LabWindows significantly reduces development time, users opting for register-level programming should possess prior experience or utilize programming languages not supported by NI. The SCXI-1163R is CE and UL certified and is built for durability, featuring solid-state relays which lack moving parts, thereby eliminating typical wear and extending their operational lifespan. Important specifications include a maximum switching current of 200 mA, a maximum working voltage of 450 V, and a maximum leakage current of 1 µA. The module dimensions are 6.8 x 8.0 x 1.2 inches, with an operating temperature range of 0 to 50 °C. Although this product has been announced as obsolete, it remains available for purchase and repairs through Apex Waves. A three-year warranty covers the module, and the user and maintenance manuals can be downloaded for reference. For pricing information, please contact a sales representative.
