The Sentry E. Labs Timed Relay can control multiple locks and devices hooked up to the same power supply. This timer can be set between seconds and minutes. The Sentry E. Labs timer uses 12v DC and you can choose from Sentry E. Labs Transformer or Sentry E. Labs Transformer with Battery backup.

This timer is compatible with all of the locking devices that we carry that do not have a built in time relay. The Sentry E. Labs timer will be the access control device for your lock system.
