STEVAL-IFP030V1

High speed digital input current limiter evaluation board based on SCLT3-8BQ7. This evaluation board implements an 8-line protected digital input termination with serialized state transfer for programmable logic controllers. It is based on the SCLT3-8BQ7 device. The SCLT3-8BQ7 enhances the I/O module density by cutting the dissipation (78mW per input) and reducing the opto-transistor count. An adjustable digital filter and an LED driver are embedded in each input section. Its 2 MHz SPI peripheral output serializes the input state transfer to the I/O module controller. The STEVAL-IFP030V1 evaluation board illustrates the flexibility of the SCTL3-8BQ7 with 8/16bit mode with parity check, temperature and voltage alarms, daisy-chain capability, adjustable digital minimal filter time (20µs /160µs). The STEVAL-IFP030V1 evaluation board can be chained with many other STEVAL-IFP030V1 evaluation boards.
