Split Valve Configuration
A common heat or cool type process requires two valves. In this case the controller has only one output.
The two motor positioners are calibrated differently, one responds to 4 to 12mA and the other responds
to 12 to 20mA. At 12mA, both valves are closed; one opening below 12mA and the other above 12mA.
Refer to Figure 20 for an interconnection diagram for split valve operation using two actuators.
