US 9,852,861 B2 · Addressable electric safety contact monitoring system

Abstract

An addressable electrical safety contact monitoring system is described. The system includes an input terminal connected to an external signal relating to a safety fault, a first signal wire connect the input terminal, a switch having a default position and an active position, a first electric connection between the input terminal and a switch, a microprocessor, a second electric connection between the microprocessor and the switch, an address-section mechanism, an output terminal and a third electric connection between the microprocessor and the output terminal. When the external signal is activated, the switch changes from the default position to the active position, the microprocessor is activated and the microprocessor activates a signal on the third electric connection corresponding to the address-selection mechanism.
