In split range control, we will control 2 outputs with time
interval. Eg :(with 4-20 ma signal, for 4-12 ma we are
operating one control instrument like valve & for 12-20ma we
are operating other control instrumet (other valve). If we
get a signal of 15ma to first instrument (Valve 1), what
will happened to the first valve, and if we get signal above
20 ma to 2 valve what will happened ?

Answer Posted / romeo

The first valve will open fully open (100%) and the second
valve will open at about 37.5% only.

Is This Answer Correct ?    1 Yes 2 No
