16-bit digital input card based on CLT01-38S4 high-speed protected digital terminal array

STEVAL-IFP023V1

Overview

The STEVAL-IFP023V1 product evaluation board allows designers to evaluate the performance of the CLT01-38S4 high-speed protected digital termination array in industrial environmental conditions. The board includes two CLT01-38S4 chips connected to an SPI bus in a daisy chain configuration. It offers a 16-bit digital input interface and indicates each sensor logic state with an LED.

Main features

8/16 input channel topology (CLT01-38S4 chip on STEVAL- IFP023V1 board)
Fully integrated current limiter
Termination for IEC 61131-2 type 1 and 3 inputs
SPI communication peripheral working at high frequency
Voltage regulator integrated on chip
Thermal/voltage alarms and checksum
Wide range supply voltage operation
Low power dissipation compared to discrete solutions
Low external component count

Overvoltage protection
ESD in accordance with IEC 61000-4-2, class 3, 8 kV air discharge, 6 kV contact discharge
Excellent EMC immunity
- High energy surge (IEC 61000-4-5), 2 kV / criteria “B” without external protection
- Fast transient burst (IEC 61000-4-4), ± 3 kV criteria “A”
- RF amplitude modulation (IEC 61000-4-6), 150 kHz - 80 MHz, 3 V / criteria “A”
SPI bus provides cost-effective isolation
Reduces overall dissipation
Compact module HTSSOP-38 package
RoHS compliant

Is there any way to make a circuit conduct for 0.1s-0.5s in the closed state and then disconnect immediately?
The time cannot exceed 0.5 seconds. Please help me with details.
This week's review information has arrived!
Hi, everyone~ I went to Shenzhen on a business trip last week and didn't pay much attention to the forum. I'm back this week~ I saw a lot of new evaluation reports~~ Let's take a look~~Southchip SC890
