DynaLock 7086 Series Programmable Digital Timer

That's what the 7086 does. It's a 365 day/24 hour digital timer for automated control of electric locks, and it holds up to 50 weekly/daily events plus 10 holiday dates. So you can unlock a lobby door at 7am and relock at 6pm on a weekday pattern, then override the whole thing on the 10 dates you program as holidays without touching the weekly schedule.

The 7086 runs on 12 or 24 VAC or VDC and draws 0.05A. Either polarity of supply works, so a standard 12V or 24V access control power supply feeding your maglocks or strikes will carry it. At 50 milliamps the draw is small enough that it won't meaningfully cut into the lock budget on that supply.

No separate relay needed for typical access control loads. The 7086 has SPDT contacts rated 10 Amps at 120VAC. Single pole double throw means you get both a normally open and a normally closed leg off the same contact, so it can drop power to a fail safe maglock or energize a fail secure strike depending on which leg you land on. Only if your load exceeds that 10 amp contact rating do you need to switch a larger relay with it.

There's one: model 7086. No finish, voltage, or handing options to specify, since the timer accepts both 12 and 24 volts AC or DC on the same unit. You order it as 7086 and wire it for whatever your supply is.

Yes, within the contact rating. The 7086 gives you one SPDT contact set rated 10 Amps at 120VAC, so it's one switched output, not one per door. If several locks are fed from the same circuit and their combined draw stays under that rating, one timer can schedule them together. Doors that need to unlock on different schedules need their own timer, because there's only the single contact set to work with.

Yes, the 7086 programmable digital timer is a commercial grade electronic access control device, not a residential plug in timer. It's meant to be wired into a low voltage access control system alongside electric locks rather than switching a receptacle.
