KABA TDM Time delay module sequencer relay

Advanced time delay module, allowing the installer to use only one time delay for any automatic door operation, electrically or magnetically locked doors, or vestibule sequencing applications. Takes one to four inputs and converts them to sequential relay outputs. As a make/break relay, eliminates mechanical binding of the locking mechanism on an automatic door. Make relay can be configured as a wet output to directly apply power to an electric locking device. To sequence vestibule sets of doors, unit provides an initial relay output for the first door, a delay between outputs 1 and 2, and another output for the second door. Also provides a delay between outputs 2 and 1, allowing you to sequence your vestibule in both directions with only one TDM. Each delay adjustable from 0.0 to 99 seconds.
