This 1734D input module is a DIN-rail mounted device with an
integrated DeviceNet communication interface, 16 ac inputs,
removable terminations, and a PointBus expansion port. The
expansion port allows you to add up to 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 1734D-IA16 uses cage-clamp terminations, and the 1734D-IA16S
uses spring-clamp terminations.

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 this module
will have this internal power bus voltage
applied, unless you use a 1734-FPD to interrupt
and change the field power-bus voltage.

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.
Installing the POINTBlock 16 Input Module
To install the 16 Input module on the DIN rail, proceed as follows:
1. Position the block module vertically above the DIN rail.
2. Press down firmly to install the module on the DIN rail. (The
locking mechanism will lock the module to the DIN rail.)
Do not discard the end cap. Use this end cap to
cover the exposed interconnections on the last
mounting base/block module on the DIN rail.
Failure to do so could result in equipment
damage or injury from electric shock.
If installing a replacement POINTBlock module to an existing system:
1. To remove the block module from the DIN rail, pull up on the
RTB removal handles to remove the terminal blocks.
2. Use a small bladed screwdriver to rotate the orange DIN rail
locking screw to a vertical position. This releases the locking
mechanism.
3. Lift straight up to remove.
4. Position the replacement block module vertically above the
DIN rail.

5. Slide the block module down allowing the interlocking side
pieces to engage the adjacent module/adapter.
6. Press firmly to seat the block module on the DIN rail. The
module locking mechanism will snap into place.

Communicating with Your Module
I/O messages are sent to (consumed) and received from (produced)
the POINTBlock I/O modules. These messages are mapped into the
processor’s memory. This POINTBlock I/O input module produces 2
bytes of input data (scanner Rx). It does not consume I/O data
(scanner Tx).
