Smart universal marshalling system from Eaton

Commenting on the accreditation milestone, Simon Westwood-Marsh, Product Line Manager for MTL Process Connectivity at Eaton, says: “We knew MTL SUM5 represented a major step-change in marshalling technology and took the latest international standards into account when we were developing the system. Third-party accreditation proves that SUM5 can be used with confidence in virtually any industrial application.”

The pioneering modular design of SUM5 brings marshalling design into the 21st century by combining five key marshalling functions – intrinsic safety (IS) isolation, signal conditioning, relay interfaces, surge protection and loop disconnect – into a single cabinet: eliminating the need for complex wiring. This simplifies procurement, inventory management and documentation significantly.

With fewer cabinets to install, process managers can reduce costs associated with installation, commissioning, 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. MTL SUM5 therefore delivers the lowest lifetime costs and lowest installed cost while saving valuable space in a control room.

MTL SUM5 now holds SGS approval to UL913 and CSA-C22.2 standards for connection to IS devices in Class I, Div 1 and Class I Zone 0, and to UL and CAN/CSA 61010 for mounting in Ordinary Locations. It has also gained approval for mounting in Class I, Div 2 and Class I Zone 2 locations.

Additionally, SGS BASEEFA has issued ATEX and IECEx certificates for mounting the MTL SUM5 in a Zone 2 hazardous area. The equipment is certified Ex ec to IEC 60079-7:2015 (Equipment protection by increased safety “e”) and so meets the Equipment Protection Level requirements for mounting in Zone 2.

This gives users confidence that the MTL SUM5 can be put into use in hazardous environments long after Ex nA protection becomes invalid and is no longer part of an ATEX harmonised standard. The certification requires the equipment to be installed in an Ex e certified enclosure providing a degree of protection of at least IP54. Eaton offers standard and customised enclosure solutions with the MTL SUM5.

In addition to these latest accreditations, MTL SUM5 holds ATEX and IECEx certifications for connection to intrinsically safe equipment.
