I have a need to build a reliable Printed Circuit Board that can do the following:
It would be powered by 24 VAC & have 12 latched on 24 VAC outputs that are turned on & off with 13 momentary switches. 13 synchronized outputs for LEDs are also needed. The 13th LED would show its off position --- & would be the default position --- if the PCB was only powered on & not made switchables with the following input.
The momentary switches other than off would only work if there was continuity created by an external 24 VAC timer that was acting as a continuous timed 24 VAC input to the proposed PCB. This would not be the power supply for the PCB. It would be from the same 24 VAC source though.
What triacs to handle the 24 VAC switching would someone more experienced recommend? Also any fresh approaches for the best way to come up with the 13 synchronized LED outputs within the circuit?
