Info
 

4 Channel Relay Module. Uses optocoupler driven relays to switch higher voltage and/or current applications with an Arduino, Raspberry Pi, Beaglebone, or other microcontroller or ARM boards.

Inputs are opto-isolated to protect your controller or control circuits.

Inputs are active low triggered -- to activate one of the relays requires the input pin being pulled to ground (GND).

You can find 3D printable enclosures for this module on Thingiverse, such as this 4-Channel Relay Module Case.

WARNING: The screw terminals and relay solder connections are exposed on the bottom of the board. Caution must be used especially when using this module with high voltages, such as mains power or any voltages greater than 12V. Always disconnect high voltage from the module before wiring or touching the module. When high voltage is supplied to the module be sure to refrain from touching or pointing to any part of the module. Working with high voltages should only be undertaken by experienced individuals.

4 of 5 Unpowered early review May 1, 2020
By: Stephen Young from Vancouver, BC Canada  
Nice and compact quad module.  A nice touch is a mechanical isolation between the output commons (the relays are Form C / SPDT) and the coil pins, via a PCB cut-through.  Another level of isolation is electrical, you can have a different 5VDC feed to drive the relay, but the DC Common is always common, so not a fully isolated set-up, i.e., keep them power supplies clean and them DC Common lines thick and intelligently routed.
Another good thing about the board are the indicating LEDs, nice touch.  4 mounting holes, a bit too near the components?
Full disclosure:  I have yet to power them up.
