In the past century, U.S. manufacturers have made great strides in improving worker safety on the plant floor. Since the 1920s, three generations of machine safety have been used in within U.S. manufacturing facilities. While early manufacturers were required to apply techniques using standard components, manufacturers today are reaping the benefits of proven and cost-effective safety networks and controllers.
More specifically, manufacturers now have the option of replacing hardwired safety systems with safety PLCs and safety networks. By switching from hardwired safety products to internationally certified, automated safety solutions, manufacturers are enjoying lower costs, heightened flexibility, and reduced chances for operator error.
