How do I calculate the Power deliviered to an electronic component by using the information found in the datasheet?
The datasheet doesn't really give enough information to calculate power dissipation accurately, and indeed it will probably vary a lot depending on what the part is actually doing.  But you want the worst case, and we can work that out.

The key figures are these lines on the datasheet:


Operating voltage Vsupply 9 V to 30 V DC
Current consumption 70 mA


Now, for a worst case calculation we assume all the energy going in is dissipated as heat in the part. We calculate this as P=IV. I is 70mA, but what do we use as V?  Well, the part will work with supply voltages between 9 and 30V.  It is up to you to choose what voltage within that range you want to use, but remember that you can't apply more than your chosen voltage to the input pins (see the inputs/outputs details table).

So for example, if you run it at 30V, then the power dissipation could be up to 30V x 70mA = 2.1W. But if you can work with 12V, then it's only 0.84W.
