STMicroelectronics STEVAL-IFP030V1 High Speed Digital Input Current Limiter Evaluation Board Evaluation Board

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 (78 mW 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: 8/16-bit mode with parity check, temperature and voltage alarms, daisy-chain capability, adjustable digital minimal filter time (20 μs /160 μs).
The STEVAL-IFP030V1 evaluation board can be chained with many other STEVAL-IFP030V1 evaluation boards.
