How Does A Pilz Safety Relay Work

Classic contact based relay technology force guided contacts relay.

How does a pilz safety relay work. Thus the final state is open. A safety relay detects wire breaks and faulty contactors actuators by sending out electrical pulses through the wiring. They meet the requirements of en 60947 5 1 en 60204 1 and vde 0113 1. The design technology is the main difference between the safety relays.

Safety relays now and in the future. When a fault occurs or a detection zone is violated they initiate a safe reliable response safety relays are encountered in almost every area of mechanical engineering mainly where the number of safety functions is quite manageable. For example one may setup a set of light curtains to allow objects to pass through it while the safety mat is activated allowing access to load or unload a machine. Timing is the other fault detection method safety relays use.

This is all done with timing. Pressure sensitive safety relays can be used in conjunction with safety mats to ensure the safety of personnel and further supplement other safety devices. If one relay fails and stays closed the other relay will still open. Two relays in parallel will be turned on together.

Two relays in series will be turned off together. In 1987 pilz patented the first emergency stop relay to protect man and machine. Safety relays are used to reduce risk. When connected to other safety relays they guarantee full monitoring of a plant or machine.
