【 摘 要 】

The paper presents three versions of astable multivibrator structures that can be made with PS-3 (Klöckner-Moeller) PLCs. They have, in their composition, two time-on delay timers (TR type) that can be found in PS-3 PLC. For each astable multivibrator circuits present the principle accompanied by graphic representations of the main signals of the astable multivibrator circuits and the mode of operation of these circuits using time diagrams. These astable multivibrator strucures can be used, special, for teaching PLCs.
