The National Instruments Switch, Load, and Signal Conditioning (SLSC) Series enhances PXI and CompactRIO test platforms by providing modular front-end signal conditioning and switching solutions. Designed to simplify system integration, SLSC standardizes connectivity, reducing the need for complex point-to-point wiring and minimizing non-recurring engineering costs. This approach improves test reliability and efficiency, particularly in hardware-in-the-loop (HIL) applications. The SLSC Series includes chassis and a range of modules tailored for various test requirements. The AL-1010 facilitates fault insertion, enabling robust failure mode testing. The ALMA-10201 and ALMA-10401 support advanced signal conditioning, ensuring accurate and reliable measurements. The OP-8913 and OP-8934 provide flexible load switching capabilities for complex test environments, while the OP-8940 offers additional signal conditioning and routing solutions.
