By adjusting the maximum and minimum inputs, you can
scale the output appropriately. See Figure 6.2.
Figure 6.2 Linear Scaling of Process Variable
for Retransmit
Maximum Output
Enter the output value (0 to 100%) which corresponds to
the maximum input.
The output will never go above the this maximum output
percentage, regardless of how high the process variable
goes.
Selectable values: 0 to 100%
Process Variable Retransmit Example: Data Logging
The CLS200 controls the temperature of a furnace. The
thermocouple in one of the zones is connected to the con-
troller and is used for closed-loop PID control. An analog re-
corder data logging system is also in place, and a recording
of the process temperature is required. The recorder input
is a linear 4 to 20 mA
Î (dc) signal representing a process
variable range of 0 to 1000˚ F.
