CLT01-8SQ7 Digital Input Current Limiter 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 CLT01-8SQ7 device, which enhances the I/O module density by cutting dissipation (78 mW per input) and reducing the number of opto-transistors. A LED driver is embedded in each input section. Its 6.25 MHz SPI peripheral output serializes the input state transfer to the I/O module controller. The STEVAL-IFP030V1 evaluation board illustrates the SCTL3-8BQ7 flexibility with: 8/16- bit mode with parity check, temperature and voltage alarms; daisy chain capability; MISOMISO/. The STEVAL-IFP031V1 evaluation board can be chained with many other STEVAL-IFP031V1 evaluation boards. The adapter board can be placed between the first STEVAL-IFP031V1 evaluation board of the chain and the STEVAL-PCC009V2 STM32x microcontroller evaluation board. This adapter offers 2 buses: isolated and non-isolated. 8 inputs - 8-bit SPI output High side input with common ground 5 V voltage regulator Package: QFN 7 x 7 - 48 L 30 V reverse polarity capable Adjustable current limiters LED output for visual status Optional 16-bit mode with parity check, temperature and voltage alarms Daisy chain capable Power dissipation 78 mW per channel RoHS compliant
