EEE World: Basics of connecting HDF27 relay using

Among the three pins 4,6,8 4 and 6 are normally closed that is 4 is be default connected to 6 and when the triggering signal or pulse is given to pin1 the connection between 4 and 6 is broken. Posted by Tux Think at 4: Connect pin 16 and cathode of the LEDs to a common point and connect the common point to the ground pin on the Arduino board.

Now load the following program into the board. Posted by Tux Think at 4: Apple Guy December 5, at 7: A relay is used to connect or disconnect a circuit based on a trigger signal.

Connect pin 4 to 5v pin on Arduino board. Newer Post Older Post Home. I have a question and i’m not sure if your still monitering this post but i am using this exact same relay with an uno and i want to use it to controll an Hvac system so my question is if i am using the 2 leads from the hvac system and they need to be connected togather would it only be pin 1 and 16 that are connected to the arduino?

Connect pin 4 to 5v pin on Arduino board.

The following figure shows the wiring diagram for the HFD The following figure shows the wiring diagram for the HFD Thus we have two relays in the HFD27 but both are controlled by the same trigger signal. The pins 1 and 16 are the pins where we need to give the trigger pulse. The same it true for the pins 13,11 and 9 hfd227.

The same it true for the pins 13,11 and 9 respectively. In the post we will see hgd27 basics of using the HFD27 relay using the Arduino uno board. A relay is used to connect or disconnect a circuit based on a trigger signal. Now load the following program into the board.

Which means the arm of the switch is connected between 4 and 6 by default and when a pulse is given to the relay the arm moved from 6 to 8, thus disconnecting 6 and connecting 4 to 8.
