The , with enhanced functionality and features, has now replaced the MTL4000 series for all new installations. The MTL4000 series is now in the termination process. Spares, of most module types, to support the installed base are still available.

For customers migrating to the MTL4500 series,  to download a comprehensive list of module comparisons.




The backplane mounting MTL4500
Series is designed with system vendors
in mind for "project-focussed" applications
such as Distributed Control System (DCS),
Emergency Shutdown Systems (ESD) and Fire
and Gas monitoring .
