  • Universal contact input supporting programmable wetting current
    Patent number: 10217573
    Abstract: A system and method according to various embodiments can include a universal contact input status detection circuit. A voltage source wets a contact with a wetting voltage. A current mirror circuit is connected across an input of the contact to provide a constant wetting current over a wide input voltage range. The input voltage can be varied over a range wide enough to include both AC voltages and DC voltages. The current mirror circuit maintains the constant wetting current during varying wetting voltage inputs across the input of the contact. A wetting voltage sensor senses the wetting voltage provided to the contact so that the status of the contact can be determined.
