1734 POINT I/O
POINT I/O
POINT I/O™ is a family of modular I/O modules that are ideal for applications where flexibility and low‐cost of ownership
are key for successful control system design and operation. As a key element in the Rockwell Automation Integrated
Architecture, its comprehensive diagnostics and configurable features allow the product to easily be applied to any
automation system and reduce engineering costs through standardization. It can be used in remote device panels, local
control panels, and can be accessed from many locations including the Internet. This product is just-what-you-need
granularity in one to eight points to reduce system cost and size.
POINT Guard I/O™ modules are safety‐rated I/O modules designed to fit into the standard POINT I/O system, offering
automation and safety functionality in a maximum density I/O solution. They are ideal for use in applications requiring
safety and automation control. POINT Guard I/O and POINT I/O can be controlled by a single GuardLogix controller for both
safety and automation control through one node. If separate safety control is required, a GuardLogix controller can be
used with POINT Guard I/O modules for safety control and a ControlLogix controller can be used with POINT I/O modules
for automation control. No changes are required to the POINT I/O system.
Benefits
Extremely fast I/O backplane uses change-of-state (COS) connections to maximize performance (polling available in
configuration mode).
Module assembly mounts horizontally or vertically (no derating required) to fit your needs.
Compact design lets it fit into limited panel space.
Auto Device Replacement (ADR) allows OEMs to add machine features and I/O modules without making changes to
the machine’s control software.
Removal and Insertion Under Power (RIUP) makes it possible to replace a module while keeping the rest of the system running.
Modular components install easily by sliding together; pull apart easily for maintenance and troubleshooting. No tools needed.
Removable wiring system for economic system commissioning, troubleshooting, calibration, and diagnostics – 70% time and cost savings.
Efficient network solutions with multiple DeviceNet interfaces, ControlNet, EtherNet/IP, and PROFIBUS DP communication adapters.
Point Guard I/O is TÜV­certified for functional safety up to and including SIL CL 3 and Performance Level (e), Catagory 4.

I/O Adapter and Communication Interface Modules
POINT I/O has two classes of communication interfaces.
An I/O adapter module provides an isolated DC/DC converter between field 24V DC and 5V backplane. You can connect up to 13 I/O modules and an I/O adapter with a
maximum of 10 A field power. Additional I/O modules require the use of one or more POINT I/O 24V DC expansion power units. An I/O adapter supports up to a
maximum of 63 I/O modules. The I/O adapter modules are available for ControlNet, DeviceNet (with and without subnet connectivity), EtherNet/IP, or PROFIBUS DP
networks.
The DeviceNet Communication Interface module interfaces I/O modules to the DeviceNet link and converts field 24V DC power to 5V DC backplane power. The
backplane power is derived from the DeviceNet network and is not isolated. I/O circuits require a power supply specified for the I/O module connected to the right of
the communication interface module. You can connect up to 13 I/O modules to the DeviceNet Communication Interface module, with a maximum of 10 A field power.

Power Supplies
All POINT I/O modules are powered from the backplane by a POINT I/O adapter module, which includes a built-in power supply, or an expansion power supply. For POINT
I/O adapters power specifications see I/O Adapter and Communication Interface Modules.
Expansion Power Unit
The POINT I/O Expansion Power Supplies extend the backplane bus power and create a new field voltage partition segment for driving field devices for up to 17 I/O
modules, depending on the current required for each module and the DIN-rail mounting position. The expansion power unit separates field power from I/O modules to
the left of the unit, effectively providing functional and logical partitioning for:
Separating field power between input and output modules.
Separating field power to the analog and digital modules.
Grouping modules to perform a specific task or function.

Field Power Distributor
The POINT I/O Field Power Distributor Module (1734-FPD) passes through all POINT I/O backplane signals, but does not provide additional POINTBus backplane power.
The field power distributor gives you the ability to change the field power distribution source for I/O modules to the right of the field power distributor. This facilitates
logical or functional partitioning of low-channel count, high I/O mix applications using any of the communication adapters. Use the field power distributor with a broad
range of voltage inputs including 5V DC to 250V DC and/or 24V AC to 240V AC applications and I/O modules.
