Time Delay Relay Circuit Diagram. Circuit diagram working the operating voltage of this circuit is 9 12v dc. In this circuit if you want to use the 5v dc supply then use the 5 volt relay instead of the 12 volt relay.
The delay timer is a device that is used to take some duration before switch on the main input supply to any equipment. How to wire a time delay relay diagrams wiring diagram is a simplified enjoyable pictorial representation of an electrical circuit. Delay timer takes on hold the supply some moment and then starts to flow.
The first circuit diagram shows how a transistors and a few other passive components may be connected for acquiring the intended delay timing outputs.
A special class of electromechanical relays called time delay relays provide delayed action either upon power up or power down and are commonly denoted in ladder logic diagrams by td or tr designations near the coil symbols and arrows on the contact symbols. The comparator two output is connected to set pin of. The wiper terminal of the variable resistor is also connected to the cathode of the zener diode. The above proposed circuit is a 1 10 minute timerwhen pot is minimum it gives 1 minute delaywhere maximum value of pot can produce 10 minutes.
