Allen-Bradley 1715 redundant I/O platform

Rockwell Automation’s Allen-Bradley 1715 redundant I/O platform requires no user programming code or add-on instructions, special wiring or additional hardware to operate. It supports multiple configurations and applications in standard and harsh environments.

Rockwell claims the 1715 I/O lets users put redundancy where it is needed. It offers simplex (non-redundant) or duplex (redundant) module operations. Modules offer native device intelligence so that they can monitor their own health with internal diagnostics. The modules perform multiple samples of a single signal using different criteria to alert users to issues such as open and short circuits, unexpected rate of change and thresholds.

In addition, the 1715 platform includes redundant ethernet adapters, which may be used to provide greater fault-tolerant capabilities.
