Receiving devices are placed in series with the ITXPlus and introduce
additional load resistances into the loop. The total loop load for a
-20 mA loop powered by supply voltage V

s

is R

loop

= 50 x (V

s

-10).

So, for example, a ITXPlus powered from a 2 V DC supply can drive a
700 Ω loop load.
