Operation
Physical Inputs & Outputs
Current Output An analog output represents a measurement value in a 4–20 mA signal to an external
process. Analog outputs can be mapped to one of the four measurements
(Measurement ID) available for a selected detector (Input ID).
To access the information on the Digital Input tabs using only the remote transmitter
keypad, see Figure A-9 .
Note:
Each input ID (Detectors 1 – 4) has four associated measurement IDs
(Measurements 1 – 4).
The analog output provides the user with additional process information from the
detector, such as pressure and density in the form of an analog signal.
There is one current output on the main board, labeled 4–20 Out A. The two current
outputs on the ISIO board are labeled 4–20 Out B and 4–20 Out C.
In the EZ Cal II software, select Current Output from the menu tree on the left to
bring up the tabs containing the current output screens.
Note:
Unless otherwise noted, the information provided about the Current
Output screens applies to the tabs for Current Outputs A, B and C.
Figure 4-14. Current Output Tabs
1. Select an Input ID and a Measurement ID from the indicated dropdowns. The
measurements in the Measurement ID dropdown are associated with the detector
specified in the Input ID field.
2. Based on the selections in these two fields, Output Type will automatically display
the measurement type, such as density, pressure or temperature, and Source (EU)
will automatically display the configured engineering units.
3. Define the output operating range by entering the Min Current and Max Current.
4. In the Min Value @ Min Current textbox, enter the minimum value, in
engineering units, that corresponds to the value entered in the Min Current
textbox.
