Farmington Hills, Mich. – PNOZelog electronic safety relays eliminate the need for mechani-cal switches within safety relays increasing life span and reducing maintenance. The product line can be used for many safety applications from emergency stopping to light curtain monitoring. The series meets European safety applications from category 2 up to and including category 4, in accordance with EN 954-1. Two microprocessors within use different hardware and software systems. The same approach is used in the semiconductor outputs. The microprocessors perform continuous self-diagnosis, signalling faults and other information to operators through LEDs.
