HFD27 005-S PDF

Thus we have two relays in the HFD27 but both are controlled by the same trigger signal. Posted by Tux x at 4: The pins 1 hfdd27 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. 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 x a pulse is given to the relay the arm moved from 6 to 8, thus disconnecting 6 and connecting 4 to 8.

Nikolar 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 x is broken.

The same it true for the pins 13,11 and 9 respectively. Now load the following program into the board. Posted by Tux Think at 4: 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.

In the post we will see the basics of using the HFD27 relay using the Arduino uno board. Apple Guy December 5, at 7: A relay is used to connect or disconnect a circuit based on a trigger signal. Among the three pins 4,6,8 hfv27 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. 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 need to give the trigger pulse. Connect pin 4 to 5v pin on Arduino board. 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.

The following figure shows the wiring diagram for the HFD A relay is used to connect or disconnect a circuit based on a trigger signal. Thus we have two relays in the HFD27 but both are controlled by the same trigger signal.
