Rockwell Automation Introduces New Line of Solid-State Industrial Relays


Allen-Bradley Bulletin 700 solid-state relays deliver cost-effective, high-performance switching solution

MILWAUKEE, July 8, 2002 - The new line of Allen-Bradley Bulletin 700 solid-state relays from complete automation leader Rockwell Automation gives industrial relay users an energy-efficient current switching alternative. Depending on the application, these solid-state relays offer a number of advantages over electro-mechanical relays, including longer life cycles, less energy consumption and reduced maintenance costs.

"Unlike electro-mechanical relays, which are rated in their number of on/off cycles, the life expectancy of solid-state relays is rated in energized hours, making them an excellent choice for applications with continuous or rapid switching requirements," said Dennis Schneider, product manager, Rockwell Automation. "In addition, the small, compact size of the Bulletin 700 solid-state relays reduces panel space requirements. And because they have no moving parts or contacts that can wear out over time, maintenance costs are lower."

The Allen-Bradley Bulletin 700 solid-state relays support a wide range of input (control) voltages. This allows them to easily interface with a variety of sensors and industrial controllers such as PLCs and process controllers, as well as the new Allen-Bradley Bulletin 900-TC temperature controllers, which together provide a cost- and space-saving solution for a range of electric heating and temperature control applications. The Allen-Bradley temperature controllers and solid-state relays are designed for easy integration into applications where users want to maximize space and functionality, with the ability to easily program, modify and respond to process changes. The 40 amp switching capability of the Bulletin 700 solid-state relays makes them well-suited to high current heating applications, such as plastic wrapping, injection molding, ovens and kilns.

Because the Bulletin 700 solid-state relays use less power and generate less heat than comparable electro-mechanical relays, users can reduce energy costs and conserve panel space due to reduced heat dissipation requirements. With no electrical coil or moving contacts, these solid-state relays offer increased shock and vibration tolerance. Some versions of the new relays also feature optional diagnostic LEDs, which simplify troubleshooting and reduce system downtime.
