9v Relay Pin Diagram. Used to trigger on off the relay normally one end is connected to 5v and the other end to ground. If you are using a 5 6v relay use a 6v power supply.
Protechtrader 9vdc 9 volt dc relay dpdt pcb 8 pin mount non latching non polarized electronic low signal high sensitivity relay module for diy electronics and arduino. 5v 5 pin relay module. The automotive iso mini relays we have been looking at above are typically available in two types of pin layout designated type a and type b layouts.
These layouts are shown on the two 5 pin relays below pin 87a not present on 4 pin relays.

Now all the pins of relay have been determined as in figure 9 below. The single channel relay module is much more than just a plain relay it comprises of components that make switching and connection easier and act as indicators to show if the module is powered and if the relay is active or not.
