TERMINOLOGY
•Split Control
Control in which two or more output signals are generated according to different functions by one input signal.
[Example] Control of two valves in different actions in order to keep temperature steady: one for cold water and another for hot
water.
Use a reverse acting Model KMP-2 (-3) for hot water, and a direct acting Model KMP-1 (-4, -V1) for cold water. When setpoint
signal increases, the hot water valve is actuated to open, while the cold water valve is actuated to close. When setpoint signal
decreases, the two valves move to opposite directions.
