Note that 15-position DO connector plug has 5 common terminals "C" (1–2, 3–4, 5–6, 7–8, 9–10), which are isolated
from each other. This can be useful when powering loads from different 24Vac sources.
A yellow LED status indicator for each relay (D1—D10) is located on the board
through the cover. Under normal operation, each digital status LED indicates activity as follows:
Off—relay open / no current flows.
•
• On—relay closed / load current flows.
Therefore, an On status indicates that the load is powered.

Analog Outputs

Analog outputs (AO) are referenced by the terminals labeled AOn and 0V (ground). Each AO can supply a maximum
of 4 mA over the entire 0 to 10Vdc range. The minimum input impedance of a device controlled by an AO must be
greater than 2500 ohms. Typical wiring for an AO is shown in
For each AO, use a VoltageOutputWritable in the station database.

NrioModule (Software) Representation
In the EC-Net station interface to the EC-BOS and IO-R-34 module, the module's I/O is modeled in the station's
NrioNetwork (copied from the nrio palette), under a child Nrio34Module "device level" component. This
Nrio34Module has a default name of "io34_n".
