Next-generation IS isolators reduce power consumption
MTL is introducing its next generation intrinsic safety isolators that incorporate its innovative One-Core technology. The two new IS isolator ranges will meet the vast majority of current and future user applications. The backplane-mounted MTL4500 and DIN-rail-mounted MTL5500 series represent the next generation in IS isolator design. Both ranges are claimed to be unique, being based on proprietary One-Core technology that makes for the extensive use of automation in manufacture. This ensures the highest quality and availability while maintaining maximum flexibility at lowest cost.
Incorporating advanced circuit design, a common set of components and innovative transformer construction, the new modules achieve a significant reduction in power consumption while increasing channel packing densities. Other user benefits include three-port isolation, low power dissipation and a quick install/release mechanism.
MTL4500 series
The backplane-mounted MTL4500 series is designed with the requirements of system vendors in mind, for project-focused applications such as Distributed Control Systems (DCS), Emergency Shutdown Systems (ESD) and Fire and Gas monitoring (F&G). 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. Easy integration with the input/output assemblies of control or safety instrumentation systems not only simplifies project engineering, but also reduces installation and maintenance costs.
MTL has an extensive range of products for all major system suppliers and the innovative connection arrangement enables new custom devices to be quickly generated to meet customer demand. The MTL4500 series is also compatible with the MTL4000 series so that existing modules can be replaced with items from the new range, thus protecting substantial customer investments.
MTL5500 series
The new 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 that 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 replace the MTL5000 series devices directly, thus keeping system downtime to a minimum.
Dermot Coady, Marketing Director of MTL, says: "MTL has always been recognised as a technology leader and the introduction of these new intrinsic safety isolators will reinforce that reputation. With project timescales and constraints becoming ever tighter, control system vendors and end users are looking for a source they can trust to deliver and implement their IS interface requirements quickly and effectively. Through the innovative use of transformer technology and other advanced electronics, our engineers have produced a product that meets these needs."
