Hardware
The following table shows the wiring of the pin strips:
VCC Relay voltage (5 V/DC)
GND Ground relay
IN1 Control signal relay 1 (5 V/DC)
IN2 Control signal relay 2 (5 V/DC)
Jumper
This jumper can be used to disconnect the supply voltage be-
tween the optocoupler and the relay.
- RY-VCC
- GND
- COM
Relay contacts
1 NC
2 COM
3 NO
The relays switch when INx is switched to GND.
The relay outputs are potential-free. You can imagine the contacts
as a simple changeover switch.
The diagram shows the assembly of the switch contact.
If the relay is switched, the respective LED on the relay lights up
as a status indicator.

• 5 V 2-Channel Relay Module for Arduino™
Description
This relay module features 2 separate relays and is ideal for
expanding your microcontroller, e.g. Arduino™, with two relay
outputs.
The control inputs are separated from the relay coils with opto-
couplers. This means that they do not interfere with the microcon-
troller, and provide additional protection against damage to the
microcontroller's digital ports.
Pin strips and screw terminals ensure easy integration into your
circuit.
