i have a switching relay and want to log the state of the relay on / off. Can i use the pulse unit to log this and show on the aranet cloud the state of the relay ?

Hi! The pulse counter only counts the amount of pulses, not the state of the relay. Also, there are limitations to the pulse length:

for this type of thing, you should probably be looking at a 0-10VDC transmitter, that would log a voltage across the relay if it is connected.
Although, the sensors also send the measurements only in 1min, 2 min, 5min or 10min intervals.
