John-Glammis The current taken by each Songle relay is about 60-70mA. The current you need to sink at IN1 is 1.5mA (connect to ground to energize relay). The total current with all 4 relays energized is 250mA + 6mA = 256mA. For details and a circuit diagram of the Opto Isolator and transistor, Google "5 Volt 4 Channel Arduino Relay user manual".Je suis désolé, mon français est terrible.

John-Glammis The instructions are a bit incorrect. P2 would be what you need for 24V (e.g. 2 lead acid batteries). I use P4 for 48V.
