MTL advances intrinsic safety isolators
29 Jan 2008
London - MTL has launched two new intrinsic safety (IS) isolator ranges. The backplane-mounted MTL4500 and DIN-rail mounted MTL5500 series are both based on a proprietary One-Core technology that facilates extensive use of automation in manufacture, which, claims MTL, provides advantages in terms of product quality, availability, flexibility and cost.
According to MTL, the new modules achieve a significant reduction in power consumption while increasing channel packing densities due to their advanced circuit design, a common set of components and special transformer construction. Other user benefits, it said, include three-port isolation, low power dissipation and a quick install/release mechanism.
The backplane-mounted MTL4500 Series is designed with the requirements of system vendors in mind, for ‘project focused’ applications such as DCS, emergency shutdown (ESD) and fire and gas monitoring (F&G) systems. The reduced power consumption and high efficiency of the isolators enables high signal densities to be achieved, together with improved freedom in cabinet layout and design.
MTL has developed a wide range of solutions for major system suppliers and the connection arrangement enables new custom solutions to be quickly generated to meet customer demand. The MTL4500 Series is also compatible with the industry standard MTL4000 Series, so existing modules can be replaced with items from the new range, thus protecting substantial customer investments.
The MTL5500 Series is DIN-rail mounting and meets the needs of the IS interface market for application-focused projects. These range from single instrument loops, through various combinations and enclosures, to fully equipped cabinets across all industries where hazardous areas exist. Within the slim, compact housing, the range of module options contains both single and multiple channel devices which enable the user to choose the functionality and integrity needed without sacrificing cabinet space.
The modules can be used for a wide variety of interface tasks for process instrumentation, routing all signal wiring through removable, coded connectors which facilitates fast installation and simple maintenance procedures. By sharing common connector elements, the MTL5500 Series modules can directly replace MTL5000 Series devices, thus keeping system downtime to a minimum.
