The ABB CA4-10 is a compact, universal, DIN-rail mounted timer relay from ABB's versatile CA4 series. The suffix "-10" indicates a specific timer function (typically On-Delay) and potentially the supply voltage range (commonly 24-240V AC/DC). It is a solid-state electronic timer designed to provide precise, reliable, and flexible timing control in a wide array of industrial automation and control applications.
