This 1734D input/output module is a DIN-rail mounted device with
an integrated DeviceNet communication interface, 8 ac inputs and 8
relay 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.
The 1734-IA8XOW8 uses cage-clamp terminations, and the
1734-IA8XOW8S uses spring-clamp terminations.

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.

ATTENTION
POINTBlock is designed to be grounded through
the DIN rail to chassis ground. To assure proper
grounding of POINTBlock and POINT I/O
!
adapters and terminal bases to chassis ground, the
recommended DIN rail material is zinc-plated,
yellow-chromated steel. Mount POINTBlock,
POINT I/O adapters and terminal bases only to
zinc-plated, yellow-chromated steel.

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.)
