The Si83418ADA-DC allows designers to evaluate the 4 channel, high-side (sourcing)/low-side (sinking) isolated smart switch with an SPI interface. The kit comes with a daughtercard only, which requires the Si83xx SPI MB to operate. The system is controlled by the Skyworks Industrial I/O Control Panel, a Python-based desktop application that runs on a host PC and interfaces with the devices in the stack via USB. Each Si83418ADA daughtercard comes equipped with 4 output channels that meet IEC 61131-2 requirements for 0.5 A outputs and can be loaded with pluggable terminal blocks for quick evaluation.

The Si83418ADA-DC is part of the Si83xx-SPI-MB portfolio, where you can order the Si83418ADA-KIT that includes the motherboard, or you can order additional daughtercards to evaluate up to 4 devices at a time. Note that KIT options come with a motherboard and daughtercard, while the DC options come with the daughtercard only. Daughtercards require a motherboard to plug into for evaluation and use of the software tool.
