Outputs for analog output modules are set at 4-20 mA. Outputs can be
assigned to represent a measured parameter such as pH, temperature,
flow or calculated values.
1. From the Settings menu, select Network Setup.
2. Select Edit Name and enter a name for the module. Push ENTER to
save the name.
3. Select an output (A, B, C, D) and push ENTER.
a. Highlight an option and push ENTER.
b. Make a selection from the list or update the entries.
c. Push ENTER to save the changes.
Option Description
Select Source Selects the output to configure—None, sensor 1 name,
sensor 2 name, calculation (if set up). For sensor output,
Select Parameter sets the measurement options. When the
measurement is autorange, Set Range sets the range.
Set Low Value Sets the 4 mA value (default: 0.000). (Range and units
depend on sensor)
Set High Value Sets the 20 mA value (default: 1.000). (Range and units
depend on sensor)
Set Transfer Sets the transfer value. Range 3.0 to 25.0 mA (default
4.000).
Set Filter Sets a time-average filter value of 0 (default) to
120 seconds.
For additional information, refer to the sc200 -20 Output Module User
Manual.
Configure the controller analog outputs
The controller analog outputs can be assigned to represent the
measured parameter or secondary measurements such as temperature
and calculations. To configure the options, highlight a menu option, push
ENTER and select an option or update the entries. Push ENTER after an
option is selected or the entries are updated.
1. From the Settings menu, select sc200 Setup.
2. Select Output Setup.
3. Select Output 1 or Output 2.
4. Choose Select Source and select a source from the list. Typically the
source is one of the sensors attached to the system. If an analog
input card is installed, the analog input may be used as a source.
5. From the Output Setup menu, choose Select Parameter and choose
an option from the list. Parameters will vary depending on the type of
sensors installed.
6. From the Output Setup menu, select Set Function and choose a
function. Further setup options will vary depending on which function
is chosen.
Option Description
Linear Signal is linearly dependent on the process value
PID Signal works as a PID (Proportional, Integral, Derivative)
controller
Logarithmic Signal is represented logarithmically within the process
variable range
Bilinear Signal is represented as two linear segments within the
process variable range
7. From the Output Setup menu, select Activation. Use the information
in the table below the chosen function to configure the options.
8. If Transfer is or will be selected as the Error Hold Mode, or if the
Transfer will be used during calibration or other functions within the
sensor menu, select Set Transfer from the Output Setup menu and
enter the transfer value.
