Ferstjoer Belied
Wy sille hurd wurkje om items nei jo te besoargjen nei it ûntfangen fan jo oarders en soargje dat se feilich oankomme. Leveringsdetails sille wurde ferskate yn jo befêstiging e-mail.Yn de measte gefallen wurde oarders ferwurke binnen 2 dagen.Under spesjale omstannichheden sil it ferlet wurde as folget: As jo in oardering pleatse op sneon, snein of offisjele feestdagen, sil it ferlet wurde foar 2 dagen..Normaalwei hat it 5-7 wurkdagen (moandei oant freed) nedich sûnder te wurden beynfloede troch fleantúch fertraging of oare miljeu faktoaren..Om't ús ferstjoer tsjinst wrâldwiid is, sille de leveringstiden ôfhinklik wêze fan jo lokaasje, sadat it in pear kear nedich wêze kin en wachtsje as jo yn ôfhandige distrikten of lannen binne.
1. Weromstjoer & Wiksel Belied
Wy akseptearje allinich items kocht fan roymall.com. As jo keapje fan ús lokale distributers of oare detailhandelaren, kinne jo se net weromstjoere op ús side.Lêste ferkeap items of frije kado's binne net akseptabel foar in weromstjoer.Om yn oanmerking te kommen foar in weromstjoer, moat jo item ûnbrûkt wêze en yn deselde steat dat jo it ûntfongen hawwe. It moat ek yn de orizjinele ferpakking wêze.Nei it ûntfangen fan weromstjoer ynstruksjes fan ús, pakket jo weromstjoerde items yn en droech jo pakket ôf by it lokale postkantoar of in oare koerier. Wy sille jo weromstjoer of wiksel item ferwurkje binnen 3-5 wurkdagen nei't wy it ûntfange. De weromstjoering sil wurde ferwurke en automatysk kreditearre oan jo orizjinele betelmiddel.Gjin weromstjoeringen of wiksel kinne akseptearre wurde as it produkt oanpast waard produsearre, ynklusyf oanpaste maat, oanpaste kleur, of oanpaste printe.Mear help nedich, nim dan kontakt mei ús op. service@roymall.com of Whatsapp: +447549870296
2.Weromstjoer Belied
Jo krije in folsleine weromstjoering of 100% winkel kredyt nei't wy it weromstjoerde pakket ûntfange en it kontrolearje. De weromstjoering sil wurde ferwurke en automatysk kreditearre oan jo orizjinele betelmiddel.Tink derom dat ferstjoerkosten en eventuele rjochten of fergoedingen net weromstjoerd wurde kinne. De ekstra ferstjoerkosten binne net weromstjoerdber as it pakket al ferstjoerd is. Jo binne ferantwurdlik foar it beteljen fan dizze kosten en wy kinne se net ôfslachtigje of weromstjoere, sels as de oardering weromstjoerd wurdt nei ús. As wy jo weromstjoerde item ûntfongen hawwe en befêstige, stjoere wy jo in e-mail om jo te warskôgjen dat wy jo weromstjoerde item ûntfongen hawwe. Wy sille jo ek ynformearje oer de goedkarring of ôfkarring fan jo weromstjoering.As jo problemen hawwe mei it weromstjoer proses, nim dan kontakt mei ús op. service@roymall.com of Whatsapp: +447549870296
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!

Q:
What voltage level is used for logic input? Will it work for 12V?

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?
