Rs latch sample

The two sides connected to Timers are inputs and the two sides with just wire are outputs.

An RS Latch is a RedPower2 Logic circuit that is basically an automatic lever that is toggled with a Redstone signal instead of manually. The sides with torches are the outputs and the other two sides are inputs/outputs. Either a constant Redstone signal or just a pulse will toggle the RS Latch to an on state and will remain in that state until the other input receives a constant signal or pulse. The outputs are always in the opposite state of each other.

At least one side is always outputting a signal. If the opposite side receives a pulse, the latch flips and starts outputing on that side and the original output side is now the new input. Also known as a 1-bit counter. Useful for turning a single pulse into a continuous signal.

Said another way, when the input receives a signal, that same input becomes an output for the signal as well. For example, a Timer connected to an input that is off will rotate for its timed duration and pulse a signal, activating the RS Latch. The path the signal used will now remain on (as well as its corresponding output) because that input became an output, which supplies the Timer with a signal that will stop it. To have the Timer start again requires a signal to the other input of the RS Latch. So, to have the Timer continue working without interruption, a Repeater can be used (which will only allow a one-way signal) placed facing away from the Timer. The picture (right) shows a RS Latch connected to two Timers to create a timed delay.  The one on the right has a Repeater/Diode in the path to prevent feedback to the Timer.

If you turn on both inputs at the same time this device will burn out.

Use a Screwdriver or Sonic Screwdriver to rotate the RS Latch.
