The National Instruments SLSC-12251 Fault Insertion Module (Part Number: 786444-01) is an integral component within the Switch, Load, and Signal Conditioning (SLSC) Series. Designed to enhance testing protocols, this module features 16 channels, each capable of supporting 8 amperes current rating. The SLSC-12251 enables the creation of precise fault conditions through its switch matrices and current monitoring capabilities. It serves as a versatile interface, connecting channels to various buses including A, B, load, and paired channels, facilitating comprehensive system evaluations. Additionally, the module operates as a voltage provider, allowing the output voltage to be proportional to the current, which can be monitored by external devices.

To ensure optimal performance, the SLSC-12251 requires calibration every two years and is compatible with NI-SLSC version 18.5 or later driver software. The module is compatible with several accessories, including RTI-12306, TB-12396, TB-12397, and the SP18M-SP18F cable. It utilizes three specialized software packages—Configuration.vi, Fault Monitor.vi, and Current Sensing.vi—for effective task execution. Although National Instruments has announced the obsolescence status of the SLSC-12251, it remains available for purchase and repair through Apex Waves. The module measures 6.89 inches by 1.19 inches by 13.21 inches and weighs 37.0 oz., and comes with a warranty of 2 to 3 years. User and maintenance manuals are available for download, and interested parties should contact a sales representative for pricing information.
