What it represents
An off-delay timer holds a specified output condition for a documented period after its initiating condition is removed. Its auxiliary power requirements depend on the selected timer.
How to read it
- Determine whether the device needs a continuing supply to complete the delay.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Show trigger removal condition
- State delay interval
- Reference supply retention requirements
A distinction that matters
Off-delay is not the same as a minimum pulse duration generated when the trigger first arrives.
