Product overview
Description
The SCLT3 series 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.
