6. Control Applications - Master/Slave Arrangement
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 mA to 12 mA and the other
responds to 12 mA to 20 mA. At 12 mA both valves are closed, one opening below 12 mA and the other
above 12 mA. Refer to Figure 29 for an interconnection diagram for split valve operation using two
actualtors.
Current Output Controller
Note: Controller must
be capable of sourcing
the impedance.
