Could you make marshalling savings?

16 December 2020

Eaton has introduced an online Return On Investment (ROI) calculator designed to help specifiers determine the savings they could expect on a project by choosing Smart Universal Marshalling (SUM) over traditional methods.

When the company launched the MTL SUM5 system, it used an example application (requiring surge protection as well as IS and loop disconnects) to estimate the savings that SUM could deliver. These included:

? 65% reduction in components through standardisation.
? 30-50% reduction in the number of cabinets required.
? Up to 80% savings on marshalling cabinet costs.
? 50% typical reduction in end user lifetime marshalling costs.

These calculations can now be made specific to individual project parameters. Users need to enter details of their marshalling cabinet design and I/O component requirements, together with the anticipated plant lifespan, and the ROI Calculator will generate the savings that SUM5 offers. 

These improvements are said to be due to the modular design and significant footprint reduction of the MTL SUM5. It combines five key marshalling functions – intrinsic safety (IS) isolation, signal conditioning, relay interfaces, surge protection and loop disconnect – into a single compact modular design: eliminating the need for complex wiring and multiple terminations per loop. The MTL SUM5 simplifies procurement, inventory management and documentation significantly. With fewer cabinets to install, project managers can reduce costs associated with installation, commissioning and testing, start-up and maintenance. 

The SUM5 modules are designed for ambient operating temperatures from –40 to +70°C and can be mounted in field enclosures in harsh and hazardous areas, as well as in cabinets within control rooms.
