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
).
