The National Instruments 786444-01 (SLSC-12251) Fault Insertion Module is a highly versatile 16-channel solution tailored for testing and validating electronic systems within the NI Switch Load and Signal Conditioning (SLSC) platform. Each channel supports a maximum continuous current of 8 A and allows for flexible switching configurations, enabling any channel to engage with a load. With a maximum handling voltage of 100 Vpeak, this module is well-suited for high-power applications.

Each channel features a current measurement output that provides a proportional voltage for precise monitoring, allowing real-time current tracking with a full-scale output of ±2 V. The module is equipped with current and overtemperature protection to ensure stable operation in demanding environments, with adjustable overcurrent limits for the Device Under Test (DUT) and buses ranging from 10 A to 29 A. Utilizing dual FET technology, the 786444-01 achieves a maximum switching rate of 30 Hz, delivering fast transition times of 5.0 µs for opening and 3.6 µs for closing, thus minimizing disruptions during automated test sequences.

In addition, built-in temperature sensors enable real-time thermal monitoring with a measurement range of -40 °C to 150 °C and an accuracy tolerance of ±2 °C, ensuring safe operation within thermal limits and significantly reducing the risk of overheating. Designed to fit into a single SLSC slot, the module has compact dimensions of 175 mm × 31 mm × 336 mm and features connections that include a female connector for the load and an 18-pin Positronic Scorpion male connector for the DUT. The 786444-01 is robustly engineered to operate under challenging conditions, with an operational temperature range of 0 °C to 40 °C and storage capabilities between -40 °C and 85 °C. The module weighs 1,050 g (37.0 oz) and is backed by a warranty of 2 to 3 years, making it a reliable choice for rigorous testing environments.
