HFD27/005-S Hongfa Telecom-Single Relay, 125V

A relay is used to connect or disconnect a circuit based on a trigger signal. 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.

The same it true for the pins 13,11 and 9 respectively. Which means the arm of the switch is hfd2 between 4 and 6 by hfs27 and when a pulse is given to the relay the arm moved from 6 to 8, thus disconnecting 6 and connecting 4 to 8.

I have a hvd27 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 hdd27 to be connected togather would it only be pin 1 and 16 that are connected to the arduino?

Now load the following program into the board. Now load the following program into the 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 triggering signal or pulse is given to pin1 the connection between 4 and 6 is broken. In the post we will see the basics of using the HFD27 relay using the Arduino uno board. The pins 1 and 16 are the pins hfd72 we need to give the trigger hfd72.

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

Connect pin 4 to 00-5s pin on Arduino board. Apple Guy December 5, at 7: Connect pin 16 and cathode of the LEDs to a hf2d7 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. Thus we have two relays in the HFD27 but both are controlled by the same trigger signal.
