Relay Module, 8 Channels, LEDs, 5V 10A Opto Isolated, Arduino, from Sydney

Relay Module, 8 Channels, LEDs, 5V 10A Opto Isolated, Arduino, from Sydney

This modules contains 8 relays, rated at 5V and 10A. Each relay has a LED indicator. It can be used to control various appliances, and other equipment with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). Each relay has an Optocoupler, providing optical isolation. Each relay also have a freewheeling diode protection. This module has a 10 pin header(standard 2.54mm pitch) for connecting power (5V and GND), and controlling the 8 relays. These pins have the following functions:

  • IN1 to IN8: Controls relays 1 to 8, active Low! Relay will turn on when this input goes below about 2.0V
  • GND: Connect 0V to this pin. Is used to power the board (optocouplers and relays)
  • VCC: Connect 5V to this pin. Is used to power the board (optocouplers and relays)

There is a second 1×3 (2.54mm pitch) pin header for supplying the “relay side” of the board with 5V. At delivery, a jumper is present on this header selecting the 5V signal from main pin header to power the relays. For default operation, don’t change this jumper!
The pins of the 1×3 pin header are marked on the PCB:

  • JD-VCC – This is the 5V required for the relays. At delivery, a jumper is present on this and the adjacent (VCC) pin
  • VCC – This is the 5V VCC supplied on the main pin connector
  • GND – Connected to 0V pin of main pin header

If opto isolation is required, an isolated 5V supply should be used. For normal operation, a jumper between pins 1 and 2 selects the 5V signal from the main pin header. This means both the “input side”, and “relay side” use the same 5V supply, and there is no opto-isolation.

For liability and safety reasons we DO NOT recommend using this module with voltages above 24V. Any use of this module is at your own risk! Always take necessary safety precautions when working with high voltages to prevent electrical shock! We will take no responsibility for any damage, personal injury or death incurred due to using this unit with high voltages!

Please note: The relays used are normally Songle or Tongling, which are both good quality and have the same specifications. During shipping to us from Asia, these modules some times get small scratches on top of the relays (from the other boards rubbing against them).

Please note these are VERY LOW cost boards from China. If you expect a premium product, this is NOT for you. These boards might have scratches on them, might not be the cleanest, and the packaging might have scratches or small tears. For example, if the board has pin headers, they are often ship to us from China all together in a bag, and the pins might be slightly bent or protrude through the bag. If this is not acceptable, please look for a more premium product. After all our costs (10% GST, over 10% eBay/PayPal fee and "Free" shipping we have to pay for), you can appreciate that there is very, very little profit margin left for us. We bring you these products at a very good price, but keep in mind it is a very low cost, cheap and nasty cheap product - exactly the same as similar price products sold by other sellers.

Orders will be shipped within 1-2 business days from receiving payment. In most cases (close to 100%), orders received before 2pm will be shipped the same day. Shipping is via Australia Post, Sendle(Couriers Please) or FastWay. For urgent orders, contact us to see if your order can be shipped the same day.

Item Location - All orders are shipped from Sydney (Castle Hill).  Your order will not be shipped from overseas, or some other location in Australia. 

Shipping - International

Shipping is via DHL eCommerce or UPS Economy. You will receive a tracking number to track your parcel. Delivery to the US and Europe typically takes about 5-7 working days. Parcels can be tracked online at:

Please contact us if you have any questions.

Returns

Faulty item: Faulty items will be replaced, or can be returned for a full refund.
Non-Faulty items: If you changed your mind, or no longer want an item, you can return it for a refund minus our processing fee, shipping fee, and PayPal fee. You must return items in their original packaging and in the same condition as when you received them. You will receive a refund, minus the shipping we had to pay for the items, and the PayPal fee. Please note that we also need to subtract the shipping fee we paid for listings that had "free shipping"! There is of course no such thing as "free shipping" for us, we always have to pay shipping. For small items below 500 grams, it is normally around $8, but can be much more for heavy items, and especially items shipped to non metro areas. For example, if you return an items that was listed with "free shipping" for $50, and we paid $8 shipping, your refund will be 50 - 8 = $42.
PayPal Fee: Since end of 2019, PayPal does NOT refund the PayPal fee any more(between 2 to 3%). So, if you decide the cancel an order, or return a "non faulty" item, you will loose the PayPal fee, because PayPal does not return it any more. Yes, this is very unfair, and there is a lot of anger about PayPal doing this, but there is nothing we can do. To avoid these refund fees, please consider using bank transfer as your payment method.
