Title: 8x Relay board question
Post by: woujer on Jun 23, 2018, 02:53 pm
Hey i always read in about the neutral screw on a relayboard and a daisy chain connection with eachother.
i'm not to familliar with relays and would like some help and explanation about these things.
Thank you!

A link to what you've read might help us to understand what you're talking about.

To explain a relay, see it as a switch that can be controlled by something else.

This is the text i'm talking about i don't don't understand what the neutral screw is on the relay.


Once adjusted, unplug your power supply. Solder wires to the positive output terminals of the buck converters used to power the pumps, leaving the negative terminals for later. For me this was the 6 and 12 volt buck converters. The length will vary depending how you may wish to lay out the electronics, but 6-12 inches (15-30 cm) should be good. These wires will be attached to the neutral screw terminals on the relay board. Make any relays that will be switching the same voltage adjacent to each other, and daisy chain their neutral terminals together. Make sure the wire you are using can withstand the current it will be subjected to. The relays and pumps will be connected later in the Assembly step.

Sounds like the amateur author is using "neutral" in the same context as "ground, 0 Volts, circuit common," etc. Can you post a link to that text?

Does he mean with neutral screw the common ?
