The Use of Safety Relays in Control Systems
The importance of assuring dangerous areas of machines are protected and are controlled reliably falls on the use of safety relays (relays with force-guided contacts) in the control system. Safety regulations and common practices in protecting man and machine have continued to increase. Safety devices and safety control applied on manufacturing cells and systems, machine tools, robots and robotic systems, and conveyor systems are mandatory today.
Driven by Occupational Safety and Health Administration (OSHA) requirements in North America and the Machine Directive in Europe, a systems safety is achieved by the use of predetermined criteria in the electrical control system. That is, that use of safety relays providing redundant, control reliable safe shutdown when an unsafe situation occurs and the safety circuit is called upon to stop the dangerous motion. It also insures that when the system is called upon to restart, all dangerous faults and potential hazards are no longer present. Riese Safety Relays provide conformance to these demands with a complete range of Safety Relay Technology.
