3. Copyright © 2007 Rockwell Automation, Inc. All rights reserved. 3 What is a Solid State Relay? A solid-state relay is a load switching device like an electromechanical relay (EMR). However an SSR uses an electronic component such as a triac or thyristor for switching AC loads and a power transistor for switching DC Loads instead of a coil and contacts like an electromechanical relay. Electromechanical Relay (EMR) Operation SSR Operation

When high frequency On/Off switching capability is required that exceeds the specification of other switching devices When the operating life requirements exceed that of an electro- mechanical switching device When it is necessary to withstand high levels of shock and vibration beyond the specifications of other switching devices When it is necessary to switch a load via a SPST-NO device; at current values of up to 100 Amps Estimated Global Market Size - $300-350 Million for SSRs RA Offers
