Fail-safe emergency-stop

Monday September 09, 2013
EAO Corporation, a global supplier of Human Machine Interface (HMI) systems and components, has introduced its Series 04 Fail-Safe Emergency-Stop Switching Element, designed to improve end-user safety.The fail-safe element will detect if the stop switch actuator becomes disconnected from the emergency-stop actuator. If there's any defect, the fail-safe contact opens, cuts power and stops the machinery as if in an emergency shutdown routine. These new contact blocks will fit any new design that uses Series 04 emergency-stop switches. Retrofitting existing applications is also an option. Following EAO’s design of other Series 04 modular products and contact block styles, these units simply snap on. Three types of connection are possible: push-in terminals (PIT) with cage clamps, or screw and plug-in terminals.
