How does one pulse ON switch close, and one on switch open?
The switch latch device timer (SLT) device in this case will just close a switch (when a momentary button is pressed) for a certain time then open it. I need to take that switching output and send a single pulse (through a NO relay) to the Play/Pause button input of a CD player that is set to Pause. That will then start it playing.
What do you need to know about pulse circuits?
Pulse Circuits – Switch – A Switch is a device that makes or breaks a circuit or a contact. As well, it can convert an analog data into digital data. The main requirements of a switch to
How big is a pulse on a switch?
Attached is a couple of circuits based on crutschows’ suggestion of an XOR gate with an RC time delay; one with a purpose-built XOR gate on the left, and an XOR gate built from 4093 Schmitt trigger quad NAND gates. As shown, the output pulse width is roughly 10mS.
How do you connect a switch to a circuit?
You connect the switch directly to one of the exclusive-or inputs and connect the switch through an RC delay (series resistor, capacitor to ground) to the other input. The exclusive-or pulse width will be approximately equal to the RC time constant. The switch output will require some type of debounce circuit, of course. Thanks for the responses.
Do you know the voltage level and duration of the pulse?
On a button press it closes a switch for a set delay then opens it. As a CD player expects a momentary button press to pause, then another to play, the switch latch and timer does not do the job by itself. Any advice will be appreciated. Do you know the voltage level and duration of the pulse needed?
How does startpulse work on a stack overflow?
Because StartPulse only works on the rising edge of the signal the LatchPulseInitial coil will only ever be set once. When the LatchPulseInitial variable goes true this will start ton1 a Timer On Delay (TON) function block.
