From Kamamilabs.com - Wiki
Description
KAmodRPi Zero 2Relay is a two-relay shield module designed for the Raspberry Pi Zero. It allows you to control devices with an operating voltage of up to 250 V AC and a current of up to 3 A or a voltage of 30 V DC and a current of 3 A. In addition to the power supply indicator, the board also features LEDs to indicate the relay's activation status. The module is suitable for home automation, industrial, and security applications.

The GPIO line outputs are connected to the control circuit via a jumper, allowing you to disconnect the corresponding pins if necessary.
Jumpers connecting the Raspberry Pi pins to the relay activation circuits
Indicator LEDs
The module is equipped with a LED indicating the presence of the supply voltage ("PWR"), and two LEDs indicating the activation of the corresponding relay ("RL1") and ("RL2").
Relay Outputs
The relay outputs are connected to screw terminals, allowing for the connection of both bare wires and wires with crimped ferrules. Both normally closed (NC) and normally open (NO) contacts are available.
