4.9.2 Analog input configuration
To configure the analog input:
1. Click I/O System on the navigation tree. The Analog Inputs tab displays ( Figure 4-28 ).
Figure 4-28: Analog input configuration
2. Click the Signal field and select 0-30 Volt or 4-20 mA from the drop-down list.
3. Click Send .
4.9.3 Analog output configuration
This configuration defines the AO value as a percentage of the full scale, or in engineering units. The
engineering units depend on the type of external device that connects to the AO.
Calibrate the AO before defining non-default engineering units for the first time. Define engineering
units from the AO Calibration screen after calibration is complete. These defined engineering units
automatically display on the Analog Output tab ( Figure 4-29 ).

See section 7.2 Analog output calibration.
4.9.4 Digital input and output configuration
The six (6) DI/DO ports support configurable input or output modes of operation.
Configure input thresholds in input mode for an input voltage range of 0 to 30 Vdc. Configure the
built-in pull-up resistor to read signals from devices with dry contact and open collector/drain output
types.
In output mode, a MOSFET Open Drain (OD) type output can sink up to 2 amps (direct current).
To configure each digital input or output:
1. Click I/O System on the navigation tree.
2. Click the Digital I/Os tab ( Figure 4-30 ).
