Description

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.

The adapter board can be placed between the

first STEVAL-IFP030V1 evaluation board of the

chain and the STEVAL-PCC009V2 STM32x

microcontroller evaluation board. This adapter

provides 2 buses: isolated and non-isolated.
