Thank you for the answer. Sending a digital high or a “1” will trigger the relay. Post as a guest Name.

This voltage is consistent with the operating voltage on the relay”. The relay should have the positive wire of the device being used connected to “IN” and to “Out 1” as shown in figure 2, and any digital signal pin on the arduino end For example jq-3ff Normally closed, which means that when the relay is off a digital low “0” is received from Arduino the device is ON Out1: Sign up using Email and Datzsheet.

Thank you very much for your answer, I hope this topic will be helpful for others too. Signal Vcc Ground On the appliance side there is: You could easily check this with an Ohmmeter or following the traces on the board. Make sure the appliance to be tinckered with is unplugged from mains.

I understand such a question can sound silly for electrical engineer, but I’m software engineer venturing in electrical world and need some guidance. We will use datashert for our example, using “out2” will simply reverse the logic, as explained above. Email Required, but never shown. datasheeh

The relay in use is: I am interpreting the picture of the printed circuit board of the relay module with accompanying notes as follows:.

Please be vary carful not to play with live circuits! So, using Out1 a “1” will turn on the device and a “0” will turn off the device. Do I need to add anything else for relay to work safely and reliably? I’ll already tested wiring and relay using LED before posting.

Retrieved from ” https: This page was last modified on 13 Juneat As Ghanima was a bit jqc-3rf explicit I’ve marked his answer as accepted. Normally open, which means that when the relay is on a digital high “1” is received from Dtasheet the dxtasheet is ON. Moreover, it even looks like relay board has diode already above VCC terminalso I wouldn’t need extra diode on IN line? From the trace on the board it would seem that the middle resistor 1 kOhm is attached to the “IN” pin serving exactly this purpose.

Sending a digital low or “0” will disable the relay. Sign up using Facebook. The diagrams below should help you understand the layout of the relay board. No large currents here, nothing to worry.

Cut and strip a portion of the positive wire so that you end up with two ends of the wire as shown in Figure 2.
