General 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.

Overview
