1715 Redundant IO Modules

Our Bulletin 1715 Redundant I/O Modules provide true redundant I/O support for critical process applications in standard and extreme operating environments. These modules offer exceptional ease of use, excellent diagnostics, and flexible configuration to support fault tolerance without the need for additional hardware or software.

Characteristic:

• Provides a flexible modular structure for user-configurable I/O applications
