This application note introduces the STEVAL-IFP019V1 demonstration board based on the VNI4140K-32 smart power solid-state relay IC, which can be used to drive lamps, valves, relays, and similar loads in industrial applications such as PLCs (programmable logic controllers).
The document introduces the STEVAL-IFP019V1 demonstration board, developed to showcase the functionalities of the VNI4140K-32 device in industrial applications such as PLCs. The board allows for the evaluation of embedded self-protections, power-handling capabilities, operation, diagnostic feedback, thermal behavior, and conformity to IEC standards.
Key features of the demonstration board include four output channels (4 x 1 A), four input channels, four feedback channels for diagnostics, a bi-directional opto-isolated interface for safe MCU connection, and compliance with IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5 standards. The board operates within a 10.5 V to 36 V DC power supply voltage range.
