i found this graph in my manual since i want to stop a motor of conveyor built , i am asking if i can connect relay 12 Volts / 2 Amps and R =1.2 kilos
also does sinking 10mA is this the maximum amperage that the camera can support ?

 

Yes a 12V relay with coil resistance of 1K2 will take 10mA, so you can use it on Sink mode.

 

i connected the relay to 12 Volt DC source and 1.2 k ohms but the relay did not work , when i connect the relay directly to 12 Volts it works and the amperage is about 64 mA
