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.

1734 POINT I/O modules offer one to eight points per module. The I/O modules are interfaced to a network through a communication interface, which includes a built-in power supply that converts incoming 24V DC power to 5V DC backplane power.The I/O modules receive power from the power supply through the backplane. Each type of communication interface supports a maximum of 13 to 17 I/O modules, with a maximum of 10 A field power. A POINT I/O assembly can be expanded up to a maximum of 63 I/O modules or 504 channels.

1734 POINT Guard I/O modules communicate by using CIP Safety protocol over EtherNet/IP for GuardLogix controllers or DeviceNet for SmartGuard 600 controllers. The application of CIP Safety protocol allows simultaneous transmission of safety and automation control and diagnostic data over one CIP network. For EtherNet/IP connectivity, use a 1734-AENT or 1734-AENTR adapter. For DeviceNet communication, use the 1734-PDN communication interface module.


POINT I/O System Components

The POINT I/O family consists of modular components. Each component snaps together and mounts onto a DIN rail to form the POINT I/O system. Required system components include:

Component Description
Communication Interface • Communication adapter modules are available for ControlNet, DeviceNet (with and without Subnet connectivity), EtherNet/IP, or PROFIBUS DP networks.
• A low-cost DeviceNet communication interface and a DeviceNet communication interface with up to 16 integrated I/O points are also available.
• Communication modules include a built-in power supply that converts incoming 24V DC power to 5V DC backplane power to power the I/O modules.
I/O Module • I/O modules plug into the POINT I/O mounting base, which mounts on a DIN rail.
• Options include: digital, analog, thermocouple, RTD, and specialty.
• Point Guard I/O modules are TÜV-certified for functional safety up to and including SIL CL 3 and Performance Level (e), Category 4.
Mounting Base • Provides the mounting location for the I/O module and the removable terminal base (RTB).
• Forms the interconnect for the I/O backplane communication and field power distribution.
• The mounting base and RTB are sold pre-assembled as a terminal base assembly.
• A one-piece mounting base with integrated terminal locations is also available.
Removable Terminal Block (RTB) • Snaps into the mounting base and provides the terminal locations for the I/O.
• The RTB separates from the mounting base and I/O module for rapid installation and commissioning of the system.

Optional system components include:

Component Description
Expansion Power Supply • Extends the backplane bus power and creates a new field voltage partition in order to support additional I/O modules, up to the maximum allowed per assembly.
• Choose from 24V DC or 120/240V AC units.
Field Power Distributor Module • Discontinues the I/O circuit power bus in order to change the field power distribution source for I/O modules to the right of the field power distributor.
• Allows a broad range of voltage inputs in the I/O assembly.

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:

Vertical mounting: 1.0 A at 5.2V DC
15.1 W at 264V AC 8.4 W at 264V AC

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.

Terminal Base Assemblies and RTBs

A Terminal Base Assembly consists of a POINT I/O mounting base and a separate removable terminal block (RTB) that plugs into the mounting base. The base mounts directly on the DIN rail, either vertically or horizontally, and includes user-selectable mechanical keying to prevent incorrect I/O module placement. The RTB plugs into the mounting base and provides the terminal locations for field wiring. It also provides vertical access to wire and screw terminations. The I/O module plugs into the mounting base above the RTB. The RTB separates independently from the mounting base and I/O module to facilitate rapid installation and commissioning of the system. Spare or replacement RTBs can be ordered separate from the terminal base assembly.

Alternatively, a POINT I/O one-piece mounting base, which includes integrated terminal locations, is also available. The I/O module plugs into the one-piece mounting base.
