Description:

The module uses genuine quality relay, normally open interfaces

Using SMD optocoupler isolation, driving ability, stable performance

The module can be high or low by a jumper setting trigger

Fault-tolerant design, even if the control line is broken, the relay will not operate

The power indicator (green), the relay status indicator (red)

The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient

Specification:

Maximum load: AC 250V/10A, DC 30V/10A

Trigger current: 5mA

Working voltage: 12V

Module size: 73 x 50 x 18.5mm (L x W x H)

Four mounting bolts holes, diameter 3.1mm

Module Interface:

DC+: positive power supply (VCC)

DC-: negative power supply (GND)

IN: can be high or low level control relay

Relay Outputs:

NO: normally open relay interface

COM: Common Interface Relays

NC: normally closed relay interface

High and low level trigger options:

It is low level trigger when jumper connect to LOW pin

It is high level trigger when jumper connect to HIGH pin

Package included:

1 x 4 Channel H/L Level Trigger Optocoupler Relay Module

It's an "optocoupler" relay module operating at 12 Volt.
Does this mean that 12 V is galvanic isolated from the arduino, that should control the relays? My first impression was: I am missing a separate ground for the relay control and for the arduino!
However, after some study I discovered that you CAN operate the board with galvanic isolated 12 V and the arduino's 5 V.
How? Don't use the straps!!
So don't connect the 4 middle pins with straps to Ground or to VCC of the relay module, but connect these 4 pins to the arduino's ground!
Now the 12V and the arduino's 5V are galvanic isolated! See photo!

A:

The module can be high or low by a jumper setting trigger. This may require you to have some circuit knowledge.

Q:
How do I wire and isolate the Arduino if there is no GND for in1-4? Does VCC and JD-VCC share a ground? Does that mean I have to trigger with 12v also?
