受保护的数字输入端接与序列化状态转移 Protected digital input termination with serialized state transfer
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.
