Programmable current limited termination

Keywords:programmable current limited termination? PCLT? proximity sensor?

The PCLT or programmable current limited termination is a dual input digital active termination device designed for 24Vdc input modules used in industrial automation. Each channel circuit terminates the connection between a high side proximity sensor and the I/O module. The PCLT features an input voltage protection. This input protection makes this device robust against EMI as defined in IEC 61000-4-x standards: ESD, fast transient bursts and voltage surges.

This document will describe the PCLT behavior, give useful recommendations to achieve robust PCLT designs regarding EMI test (IEC 61000-4-5 and 4-4) as well as give information on thermal behavior of PCLT in its application and describe the demonstration board and recommendations for use.
