Signal conditioners for safe areas

May 2015 IS & Ex

Eaton has launched a new series of signal conditioners for safe-area applications – the MTL1000 series. Process managers can now specify Eaton’s signal conditioners for all areas of the plant, enabling them to reduce the complexity of their supply chain and save on operational costs. The MTL1000 series is designed to ensure reliable and high quality communication between the field device and control units located in the plant, and are ideal for safe areas in the oil and gas industry, chemical, petrochemical and pharmaceutical plants.

These compact devices are quick and easy to install and feature a special power system which reduces wiring by up to 30% and lowers installation time and associated costs. With less wiring, risk of installation error is also reduced, assisting with on-time plant start-up and improved reliability over the lifetime of the installation. In addition, more space is available in the panel board which allows for a higher density of signal conditioners.

“For large installations of signal conditioners, a wiring reduction of up to 30 percent can save a lot of space and allow users to have clear access to the modules,” says product line manager Roger Highton. “With the new MTL1000 Series, we bring more than 40 years of hazardous area experience and industry expertise to safe-area applications, enabling customers to benefit from a single source supplier that will enhance the integrity of their supply chain and lead to cost savings. Using the MTL1000 Series, our customers can now specify reliable signal conditioners for use throughout their plants, in both hazardous and safe areas.”

Eaton’s intrinsically safe isolators are reliable in hazardous areas and the new MTL1000 Series complements this range and offers high quality signal conditioning for general purpose applications. With an operating temperature range of -25 to 60°C, the MTL1000 Series is designed for long-term protection with a product life in excess of 10 years in even the most demanding of environments.

Eaton’s signal conditioners use galvanic isolation which is designed to prevent transmission and control errors which can lead to an interruption in the safe processing and monitoring of control signals. The MTL1000 Series is engineered to make sure that excessive voltages and noise do not affect the overall communication and can amplify, convert or isolate signals. The new signal conditioners provide excellent protection for equipment and personnel, so equipment and plants can operate safely and efficiently.
