Split Range Operation
Split ranging permits operation of two valves in sequence from one 4-20 mA control signal. To
accomplish this with the 4700E/4800E, the two positioners are connected in series as shown in
Figure 16, with the actual split ranging done by proper cam segment selection per tables in “Cam
Lobe Selection and Lever Arm Orientation” on page 65.
NOTE With this configuration, the voltage burden of the 4-20 mA
controller is 10 V instead of 5 V.
