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

SCLT3-8BQ7, SCLT3-8BT8 Datasheet Octal industrial digital input current limiter with serialized output QFN-48L 7.0 x 7.0 x 0.

Key Features
