8 CHANNEL OPTO ISOLATOR FULL

This is because 1 W of power from the +12V supply only requires about 83 mA ( 12 V x 83 mA = 1 W ) however at say 70% efficiency of the 5 V regulator, this goes up to about 120 mA (83 mA / 0.7) but NOT the full 200 mA. For example: 200mA at +5VDC (1 Watt) does NOT mean the +12V supply needs to supply an additional 200 mA also.

Note that the switching regulator on the Relay Board should somewhat efficiently (say 70%?) convert the board's 5V power usage to 12 V power input requirements.

Because one may use the board's +5 VDC output (2 pins) to power an Arduino/PIC circuit, use a 12V power supply that can provide MORE than 500mA (depending on your circuit's requirements).

So max supply current is 8 mA + (16 x 30 mA) = 488 mA (actual measured was 500 mA).

Each relay requires about 30 mA when on.

About 8 mA is required with all relays off.

The drive to each control input pin must 'sink' 3mA when low (low = relay ON).

8 CHANNEL OPTO ISOLATOR DRIVER

5V 8-Channel Relay Interface Board, each one needs 15 – 20mA Driver current.Optically Isolated relays protect your microcontroller from damage if the equipment being controlled fails.It also has high Impedance input pin so not to draw any more current than required from the controller. You can use it to control both DC and AC lines and it also has LED indicators to indicate the state of operation of the module.

It can be controlled directly with both 3.3V and 5V microcontrollers easily.

This 8-channel Relay module comes with Optocoupler protection is an active low relay module which means that the relay will conduct when the input signal falls below 2V and if it is above 2V then the relay is turned off you can also make it an active module by changing the jumper position on the power module. Relays are also used to provide electrical isolation between two circuits. We use relays in control applications, switching applications, circuit protection applications and load transfer applications. Relays are important part of any electrical and electronic circuits.
