POINT I/O Family
Overview
The POINT I/O family has 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 be easily 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 has just-what-you-need
granularity in 1 to 8 points to reduce system cost and size.
Available features include Channel Level Diagnostics for quick
troubleshooting, multiple termination options and flexibility to save money,
cabinet space and commissioning/troubleshooting time, the ability to
mix/match Safety I/O on the same bus, and available DeviceLogix for local
control, fast response time. Self-Configuring modules are also available to
reduce/simplify your design and your inventory.
