Description
AI
The CLT01 series is an octal industrial digital input IC, which drastically reduces the power dissipation of the digital input modules. Its current-sinking inputs can be configured for type 1, type 2, or type 3 inputs as per IEC 61131-2 with few external components.
The CLT01 series includes a serial interface, which translates, conditions, and serializes the data to CMOS-compatible signals through SPI. Combining its daisy-chaining capability with its accurate current limitation, the CLT01 series enhances the I/O module’s density by cutting the power dissipation and reducing the number of optocouplers.
The CLT01 series can be evaluated thanks to the STEVAL-IFP031V1 evaluation board. For detailed application guidelines, refer to the AN4625.
