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!
