Time delay relays are like normal relays however introduce a timing element in order to intentionally delay when the relay either turns on (energises) or turns off (de-energises). Used typically to control various types of equipment throughout many types of industries. Factory automation, production processes, lighting control, air conditioning, electrical distribution to name a few.
There are numerous types of Time delay relays available, each designed to carry out a particular operation/sequence known as a “function”. Each function has it’s own particular name in order to identify what the relay is designed to do.
When designing an application, it is important to know what particular timing function is required to carry out a specific task. In most cases the most popular timing functions will suffice. These being:
Delay On (Supply Initiated)
Product recommendation: LEDO
Delay Off (Switch Initiated)
Product recommendation: LESW
Interval (Supply Initiated)
Product recommendation: LEIN
Asymmetrical Recycling (Supply Initiated)
Product recommendation: LART
