Product Description

Our AZ-Delivery Relay modules can connect many switching processes quickly and reliably. Thanks to an additional transistor, the module can handle most switch microcontrollers with little power. The relays used are generously dimensioned to enable long-term work even under unfavourable operating conditions. The optocouplers and diodes protect your controller from damage, and the source of the power supply can be configured with a jumper on the board.

The relays are often used in remote control, communication, mechatronics, power electronics, etc. They can also be used to drive powerful voltage / current electronics (such as AC or DC motors, AC devices, etc.) from microelectronics (microcontrollers, sensors, etc.)

Details

Optocoupler and diodes to protect the controller.
It is a robust module for many reliable switching operations.

Particularities

Compact design and large capacity: this 16-Relay module can switch high currents up to 5A.
Compared to other relay modules, the AZ-Delivery relays are generously dimensioned to enable long-term work even under unfavourable operating conditions.
With the help of a jumper, you can configure the power supply source.

Technical Data

Type:	16-channel
Dimensions:	180 mm x 90 mm [7 x 3.5in]
Maximum DC:	5A 30V
Maximum AC:	5A 50V

TTL Control Signal:	5V DC
Contact Type:	Both (Normally Closed - NC, Normally open - NO)
Power Supply:	12V DC (additionally required)

Big capacity

Thanks to the ability of the module to switch high currents up to 5A and to work in unfavourable operating conditions, it can be used for a variety of projects.

Breadboard compatible

The module has a socket and a pin header which makes connecting with a breadboard extremely easy and prototyping very pleasant.

Very useful
Reviewed in the United Kingdom on 11 January 2021

Quite simple to operate. There are two rows of eight relays that are controlled by 5v data pins. With each data pin connected to a hi/low output from an Arduino the corresponding relay is switched one way or the other. The voltage supplied to the relay in question is then routed to that side of the relay.

Oh the voltage and ground are to supply the circuit itself.

Although the circuit voltage itself is 5v which controls the relays, each relay can use upto 12v.

Very good value. Unlike some of the reviews I can't fault the soldering on the 3 boards I received. I would have preferred if the interface was a shift register, as it requires 16 I/O pins. The pins are active low.

Awful. Buyer Beware.
Reviewed in the United Kingdom on 24 October 2024
Number Of Items: 5Verified Purchase
5 pack of 12v 16 channel relays at face value is a bargain.
Expectations vs what I actually received is the problem.
Of the 5 relay boards, 4 are either badly assembled, damaged components, capacitors with broken legs, partially pulled away from board, no good. Badly soldered components, relays which are all not flush, cold weld spots and overall non functional.

Of the one working board, that is fine. This felt like a 4 were QA rejects which were sold anyway and a one working board was included for good measure. So I have PCBs with components which i might strip and have to spares and use elsewhere, but only because I hate waste. Of the one board which is OK, I am going to treat this as likely to be a problem in future and so this is only going to get light duty low power occasional use, again, waste not.

Spend a few points more and buy something quality.

Arrived damaged. Appears to have been repaired.

Number Of Items: 1Verified Purchase
Arrived sealed in an anti-static bag as expected but after opening was found to be damaged.

Upon closer inspection (See images) you can clearly see awful re-soldering around an LED, the side of one of the relays has been melted (Likely from the re-soldering) and poor soldering on one of the capacitors.

I believe this item was tested before being packaged and it was discovered to be faulty and repaired, badly.

I have no doubts the LED and capacitor have been replaced. A quick test does show this unit to be working.

I haven't decided if I am going to return this item yet but if I do decide to keep this I would have to touch up the poor soldering.

16er Relaismodul
Reviewed in Germany on 6 September 2019
Number Of Items: 1Verified Purchase
Die Platine ist sauber verarbeitet und funktioniert auf Anhieb, so wie wir
das von Produkten, die von AZ-Delivery vertrieben werden gewohnt sind.

Das Modul besitzt eine leicht zugängliche Doppel-Pinreihe an der kurzen
Seite, die nach oben ausgeführt und auf der Platine beschriftet sind, leider ist die
Schrift etwas zu klein - ohne Lupe nicht erkennbar. Die Anschaltung
ist auf einem Bild bei amazon.de gut ersichtlich, auch gibt es ein eBook
aus dem die Beschaltung problemlos hervorgeht. Das Beschaltungsbild
von amazon.de sollte auf der AZ-Delivery-Homepage auftauchen. Die
Beschaltung ist (von oben nach unten, Pinreihe links, linke Reihe):

VCC (mit +5V vom Netzteil beschaltet)
IN1 (kann direkt am µC-Port angeschlossen werden)
IN3 (kann direkt am µC-Port angeschlossen werden)
IN5 (kann direkt am µC-Port angeschlossen werden)
IN7 (kann direkt am µC-Port angeschlossen werden)
IN9 (kann direkt am µC-Port angeschlossen werden)
IN11 (kann direkt am µC-Port angeschlossen werden)
IN13 (kann direkt am µC-Port angeschlossen werden)
IN15 (kann direkt am µC-Port angeschlossen werden)
GND (Ground, mit 0V vom Netzteil beschaltet)

(von oben nach unten, Pinreihe links, rechte Reihe):

VCC (mit +5V vom Netzteil beschaltet)
IN2 (kann direkt am µC-Port angeschlossen werden)
IN4 (kann direkt am µC-Port angeschlossen werden)
IN6 (kann direkt am µC-Port angeschlossen werden)
IN8 (kann direkt am µC-Port angeschlossen werden)
IN10 (kann direkt am µC-Port angeschlossen werden)
IN12 (kann direkt am µC-Port angeschlossen werden)
IN14 (kann direkt am µC-Port angeschlossen werden)
IN16 (kann direkt am µC-Port angeschlossen werden)
GND (Ground, mit 0V vom Netzteil beschaltet)

Das Relaismodul muss durch eine externe Spannungsversorgung
beschalten werden, so dass die benötigte Energie nicht vom µC geliefert
wird (benötigte Ströme zu groß). µC und externe Spannungsversorgung
müssen dazu massegleich verschaltet werden, dafür sind für die eSV
Lüsterklemmen vorgesehen. Die Spannungsversorgung ist zudem
durch Kondensatoren stabilisiert/gepuffert.

Laut Beschaltungsbild (Amazon oder eBook (PDF) sind 12V
notwendig, abgebildet ist aber ein 9V-Block. Gut wäre, wenn
der benötigte Spannungsbereich angegeben wäre. In meinen Tests
hat die Schaltung nicht mit einer 9V Batterie funktioniert, es war eine
12V eSV notwendig.

Die Stromaufnahme ist im eBook (PDF) leider nicht angegeben :-(

Die Ausgänge des Relais' sind auf der Platine beschriftet, so dass klar ist,
wo COM / NO und NC verdrahtet sind.

Leider sind die PINs nicht abgeklebt, so dass bei Beschaltung mit
Netzspannung bauseits eine Isolierung vorgesehen werden muss.

Der Relaisbaustein schaltet bei einer logischen 0 am µC das Relais,
der µC ist durch den Optokoppler ideal vom Relais abgeschirmt.

Die Relais werden zuverlässig ab 3,6 V ein- und ab 3,7 V ausgeschaltet.
Leider ist deshalb der verwendete Optokoppler nicht für die Schaltung mit
3,3V geeignet, dadurch kann das 16-Relais Modul nicht mit dem
Raspberry Pi genutzt werden :-(
Optional kann hier 2x das 8-Relais Modul genutzt werden oder
es muss eine Transistor-Treiberstufe vor das Modul geschaltet
werden.

W opisie tego moduł przekaźników, firma AZDelivery podaje, że posiada on separację galwaniczną obwodów poprzez zamontowane opto-izolatory. Faktycznie moduł ten posiada zamontowane opto-izolatory ale nie są one prawidłowo połączone.

Brak opisywanej przeze mnie separacji obwodów można bardzo łatwo sprawdzić - podłączając moduł przekaźników pod zasilanie 12V oraz 5V i GDD bezpośrednio z płytki przekaźników do płytki Arduino. Przy takim podłączeniu (którego szkic znajduje się w tej ofercie ), Arduino działa - czyli jest zasilane bezpośrednio z płytki przekaźników! Gdzie jest więc separacja obwodów zasilających od sterujących ??
