1734 POINT I/O Modules

POINT I/O is a family of I/O modules that are ideal for applications where

flexibility and low-cost of ownership are key for successful control system

design and operation. POINT I/O 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 I/O modules feature:

• A highly modular design with 1 point to 8 point modularity

• Broad application coverage

• Parameter-level explicit messaging

• Removal and insertion under power

• Channel-level open-wire detection with electronic feedback

• Robust backplane design

• Built-in DIN-rail grounding

PLC-5 controllers support POINT I/O over these networks:

• DeviceNet

• ControlNet

• PROFIBUS DP

When you select POINT I/O modules, you must also select:

• A communication interface

• I/O devices based on field devices

• Wiring base assembly

• Power distribution modules
