16-Channel 12V Relay Module Board
inc. DuPont cable
This is a 16-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, Raspberry, AVR, PIC, ARM, PLC, etc.
Widely used for all MCU control, industrial sector, PLC control, smart home control.
The relay board is able to control various appliances and other equipment with large current.
The 16-channels are optically isolated for safe, reliable & anti-interference operation.
LED lights indicate relay channel operation.
Opto-Isolation
The board includes opto-isolators on the logic inputs.
Opto-isolators provide complete electrical isolation between the logic control input and the relay power as an added layer of protection in case of a lighting strike or some other kind of major failure on the AC load of the relay.
In addition, this module also has an LM2596S voltage regulator to power the relay circuit and possibly an external microcontroller board.
Please note: it is advisable not to power a microcontroller via the relay board and a USB port at the same time.

You will need to pay for the cost of returning the item(s) and the item(s) remain your responsibility until we receive them.
Damaged caused during transit must be notified within two days of the delivery.
All items sold as tested are genuinely tested before dispatch.
Product(s) which show obvious signs of misuse, damage or weather damage will not be eligible for refund or replacement.
All items are security marked.
Please ensure all security markings and stickers are intact or any warranty offered will be void.
All items are subject to satisfactory inspection of the anti-tamper warranty sticker/seal.
Any evidence that these aforementioned stickers/seals have been removed or broken will render the item out of warranty and will not be covered under warranty rules.
If the item becomes faulty within that period a replacement will be issued free of charge upon receipt of the faulty item, back to us, if proved to be faulty upon inspection.
If the item is not faulty or can be repaired, not to the detriment of the item, then this shall be undertaken rather than direct replacement.
Warranty Exclusion: Please note that as batteries are "consumables" we only provide dead on arrival warranty.
The maximum capacity of all rechargeable batteries fades with time depending on application and usage patterns.
This is considered normal - therefore, a change in battery capacity is not covered under warranty.
Battery life is not warranted and will vary depending on usage.
Please note- Any software is not covered by the warranty policy. Please refer to the copyright owner for specific details.
