MTL F809F-Plus fieldbus diagnostics module

The Crouse-Hinds series MTL F809F-Plus Fieldbus Diagnostic Module continuously monitors the performance of eight fieldbus segments, providing information on the health of the network physical layer. It mounts on a range of MTL power supply carriers and collects diagnostic information without interruption to normal fieldbus communications.

As a Foundation Fieldbus™ device the MTL F809F-Plus easily integrates with the chosen host control system via a fieldbus segment, allowing the network status and measured parameters to be displayed in the control system’s instrument management software.

The F809F-Plus builds on the success of the F809F, the industry’s first fieldbus-connected diagnostic module. New features of the F809F-Plus version include superior immunity to noise on the ‘communicating’ segment, enhanced short-to-shield detection and extended power supply voltage measurement range for compatibility with new MTL power supply types. It may be used as a direct replacement for F809F in existing installations; when installed using appropriate DD files the full feature set of F809F-Plus become available with immediate effect.

The F809F-Plus is available with fully updated versions of eEDDL and FDT/DTM user interfaces that are free to download from the eaton.com website. Improvements include faster operation and clearer screen layouts, leading to an enhanced user experience. The user interfaces comply with NAMUR specification NE107 'Self-Monitoring and

Diagnosis of Field Devices', providing clear standardised diagnostic alerts using three of the four categories; maintenance required, out of specification, and failure.
