TDM Universal Time Delay Module

Time Delay Module, Provides up to 4 Inputs, Can be Converted to Sequential Relay Outputs, Each Output Adjustable 0-99 Seconds, High Current

The TDM-HC is a multipurpose microprocessor based timing module that can be used for a variety of applications. Its unique design and open architecture allows the TDM-HC to be used in any type of application that requires timing control of up to two outputs with up to four inputs. The first output of the TDM-HC has a capacity of 20 amps, making it compatible with every electronic locking device, including electric latch-retraction exit devices.

Common Applications include:

• Using the TDM-HC to provide a simple time delay of 0-99 seconds.
• Using the TDM-HC as a make/ break relay to eliminate mechanical binding of the electrical locking mechanism on an automatic door.
• Using the TDM-HC to sequence vestibule doors. One unit is capable of sequencing the vestibule doors from both directions.
• The four inputs on the TDM-HC allow sequencing or independent operation of the two outputs.
  • Input 1 will sequence Output 1 then 2.
  • Input 2 will sequence Output 2 then 1.
  • Input 3 will operate Output 1 independently.
  • Input 4 will operate Output 2 independently
