Access control with bistable outputs, T-input

This example shows the use of the SL-22 Toggle input.

We want to use a clocking to permanently unlock a door and use the next clocking to permanently lock it again.

We are using a standard access controller with a voltage-free output. A short pulse on the access controller’s output toggles the OUT1A (and OUT1B, which can be used to monitor the state of the door lock).
