It features a single changeover (1CO) contact, allowing the relay to switch between normally open and normally closed positions. The "AU" designation could indicate a specific feature or material used in the relay, while "C1D2" signifies that it is certified for use in hazardous environments (Class 1, Division 2), where flammable gases or vapors may be present under certain conditions. For detailed specifications, it’s best to consult the manufacturer’s datasheet.
