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.
