STEVAL-IFP031V1, EVALUATION BOARD, CURRENT LIMITER

High speed digital input current limiter evaluation board based on CLT01-38SQ7. This evaluation board implements an 8-line protected digital input termination with serialized state transfer for programmable logic controllers. It is based on the CLT01-38SQ7 device, which enhances I/O module density by reducing dissipation (78mW per input) and the number of opto-transistors. A LED driver is embedded in each input section. Its 6.25MHz SPI peripheral output serializes the input state transfer to the I/O module controller. The STEVAL-IFP031V1 evaluation board can be connected in daisy chain with other STEVAL-IFP031V1 evaluation boards. The adapter board can be placed between the first STEVAL-IFP031V1 evaluation board in the chain and the STEVAL-PCC009V2 STM32x microcontroller evaluation board. This adapter offers two buses such as isolated and non-isolated.
