Designed to provide an alternative to electromechanical relays, the Allen-Bradley Bulletin 700 solid-state relays (SSRs) support a wide range of input (control) voltages, allowing them to freely interface with a variety of sensors and industrial controllers, such as PLCs and process controllers. Unlike electromechanical relays, which are rated in their number of on/off cycles, the life expectancy of these solid-state relays is rated in energized hours, which suits applications with continuous or rapid switching requirements. The new SSRs also boast of other advantages over electromechanical relays, such as longer life cycles and less energy consumption. Their small size reduces panel space requirements, and a lack of moving parts shrinks maintenance costs. With a 40A switching capability, the Bulletin 700 SSRs also support high current heating applications, such as injection molding, ovens and kilns. With no electrical coil or moving contacts, the solid-state relays also tolerate increased shock and vibration. And some versions include optional diagnostic LEDs.
