Description  
Power supply and input protection, R = 2.2 kΩ:  
I
The SCLT3-8BT8 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.  
– IEC 61000-4-4 transient burst : 4 kV  
minimum  
– IEC 61000-4-5 voltage surge: 1 kV  
minimum  
– IEC 61000-4-2 ESD: 8 kV in contact:  
15 kV in air minimum  
Wide range power supply voltage V :

– + 9 V to + 35 V with 10 mA output current  
– Protected against -30 V reverse polarity
