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. https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2013-10-11 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2021-04-03 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2021-04-16 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2021-07-17 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2021-12-04 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2022-04-07 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2023-03-23 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2024-01-07 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2024-06-24 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2024-12-26 https://elecena.pl/product/4441398/clt01-38s4-high-speed-protected-digital-termination-array 2025-07-13
