CLT3-4 termination in industrial automation logic inputs
STEVAL-IFP008V1

Introduction
The CLT3-4B (Current Limited Termination) is a quadruple logic input termination for sensor
or mechanical switch interfaces. It is designed to work in 24 VDC applications such as
Programmable Logic Controller PLC, Programmable Automation Controller PAC, and
Distributed I/Os systems used in factory automation.
The device optimizes the input VI characteristic to reduce power dissipation. This b
