Description  
Input digital filter with adjustable delay: 20 µs  
The SCLT3-8BQ7 provides an 8-line protected  
digital input termination with serialized state  
transfer. This device enhances the I/O module  
density by cutting the dissipation (78 mW per  
input) and reducing the count of opto-transistors.  
An adjustable digital filter and an LED driver are  
embedded in each type 3 input section. Its 2 MHz  
SPI peripheral output serializes the input state  
transfer to the I/O module controller.  
to 3 ms  
Power dissipation: 78 mW per channel  
Complies with following standards:  
IEC61000-4-2:  
– ±8 kV contact discharge  
– ±15 kV air discharge
