Abstract

This article described four kinds of time-delay contacts (delayed on of normally open contact, delayed off of normally closed contact, delayed off normally open contact, delayed on of normally closed contact)technique using the PLC timer to implement time-relay, extension, and the timer changed the set value and square-wave generator method for improving the precision of timing. The ladder diagrams and waveforms have been verified in Panasonic FP1-C72PLC control unit, and you can use them directly.
