Improved one-shot timer circuit composed of 2 PUT

Posted on Feb 6, 2014

Figure 1 is an improved trigger timing circuit composed of 2 PUT. If you add the set signal, the circuit will be set, transistor VT1 turn to the conduction state, the relay K will be energized action. It supplies voltage for the delay voltage at the same time. Therefore, the capacitor is charged by C1. PUT1 is conducted by positive voltage. C1 passes PUT1,..
