HONGFA PCB Relays Series HFD27

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. Thus we have two relays in the HFD27 but both are controlled by the same trigger signal. Now load the following program into the 050-s. In the post we will see the basics of using the HFD27 relay using the Arduino uno board.

In the post we will see the basics of using the HFD27 relay using the Arduino uno board. 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 hf27 signal or pulse is given to pin1 the connection between 4 and 6 is broken.

The pins 1 and 16 are the pins where we need to give the trigger pulse. 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. Apple Guy December 5, at 7: 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?

The following figure shows the wiring diagram for the HFD 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.

Connect 05-s 4 to 5v pin on Arduino board. The following figure shows the wiring diagram for the HFD A relay is used to connect or disconnect a circuit based on a trigger hdf27. Now load the following program into the board. Connect pin 4 to 5v pin on Arduino board. Newer Post Older Post Home. Posted by Tux Think at 4: Newer Post Older Post Home. The same it true for the pins 13,11 and 9 respectively.

Thus we have two relays in the HFD27 but both are controlled by 005s- same trigger signal. The same it true for the pins 13,11 and 9 respectively. 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.

The pins 1 and 16 are the pins where we htd27 to give the trigger pulse.
