16 Channel 16 Way 12V Logic Relay Shield Module With Optocoupler NEW UK Seller
3 in stock
This is a high quality board incorporating 16 x 12V DC Relays which allows for easy switching of higher voltages and are ideal for use with a microcontroller such as a PIC, Arduino, ARM or AVR.
This is a high quality 12V DC Relay module using low power SMD components, allowing for easy switching of higher voltages and are ideal for use with a 12v Power supply.
remember most microcontroller such as a PIC, Arduino, ARM or AVR are
3.3v or 5v and therefore a seperate 12v power supply will be required to
power these relay modules, with the logic control coming from the
The relays used in this module can switch up to 10A at 250V AC, or up to 10A at 30V DC.
An LED indicator shows which relays are currently on.
Inputs are Active Low and need to sink approx. 5ma per input
If the input voltage is low this energises the relay, the relay’s NO (Normally Open) contact is connected to the relay’s COM (common) contact.
If the input voltage is high 12v, this de-energises the relay’s NC (Normally Closed) contact is connected to the relay’s COM (common) contact.
On the 2 way Terminal Block marked VCC and GND, supply your 12v Voltage. For each relay that energises you will need approx. 45ma current to drive each relay coil. So if all the realys are energised your 12v supply must be able to provide approx. 720mA.
