8-Channel 12V Relay Module
8-Channel 12V Relay Module

Ready to get switching on your Raspberry Pi?! This neat relay module features 8 x 12V relays rated at 10A/250V each. It's designed to switch up to 8 high current (10A) or high voltage (250V) loads from a microcontroller!

Each relay can be individually switched on/off by an opto-isolated digital input, which that can be connected directly to a microcontroller output pin. It only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 12V. This makes it ideal for 3.3V, 5V & 12V devices.

Features

  • 8 x 12V Relays
  • Board Size: 14cm x 5.5cm
  • Relay Rated: 10A / 250VAC / 30VDC
  • Relay Draw Current: 30mA @ 12V
  • Power Supply: 8V to 12V
  • Fully Opto-Isolated Input Signals
  • Input Signal Voltage: 1V to 12V
  • Individual Indicator LEDS for Each Relay
  • Power On LED Indicator
  • Isolated Input GND
  • 4 x M3 Mounting Holes
  • Manufacturer: Keyes 8R1A

How to Use

Connect a supply voltage of between 8V and 12V to the VCC and GND pins. This is used to power the relay coils when they are switched on. A power Indicator LED indicates when power is supplied. Ensure that power is applied in the correct polarity (+) to VCC, and (-) to GND. Applying power the wrong way round will damage the board!

The jumper acts as a shorting link which links the signal ground to the power ground. If you want full isolation for your microcontroller from potentially noisy relays, this link can be removed.

Therefore, remover the jumper, and input signals from your microcontroller should be supplied between the COM pin and each input pin. COM should be connected to your microcontroller's GND. The relay input pin (IN1, IN2, IN3 etc.) should be connected to the signal voltage line from your microcontroller. We recommend that you place a current limiting resistor in-line with your input pin and the relay input.

To switch your chosen relay e.g. IN1, will switch relay 1, apply the signal voltage.
