This 1734D input/output module is a DIN-rail mounted device with
an integrated DeviceNet communication interface, 8 inputs and 8
outputs, removable terminations, and a PointBus expansion port.The
expansion port allows you to add up to a maximum of 12 additional
POINT I/O modules.
The module includes a non-isolated DeviceNet communication
interface. The 24V dc from the DeviceNet connection powers a
non-isolated dc/dc converter that generates +5V dc which powers the
POINTBlock electronics and connects to the PointBus port to power
the expansion I/O electronics.

ATTENTION
Whatever field power you supply is connected to
the internal field-power bus. For example, if
120V ac is applied to the power connections,
there will be 120V ac applied to the modules
through the internal field-power bus.
POINT I/O modules to the right of the module
will also have that internal power bus voltage
applied, unless you use a 1734-FPD to interrupt
and change the field power-bus voltage.

To set the node address, set the combination of 1’s and 10’s to
correspond to the required address. (For example, for 61, set
the 10’s switch to 6 and the 1’s switch to 1.)
