SCLT3-8BQ7中文资料具有数字滤波器的高速数字输入限流器数据手册ST规格书

描述 Description

The SCLT3 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 SCLT3 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 SCLT3 series enhances the I/O module’s density by cutting the power dissipation and reducing the number of optocouplers.

The SCLT3 series can be evaluated thanks to the STEVAL-IFP030V1 evaluation board. For detailed application guidelines refer to AN2846.
