The ABB CR‑S024VADC1CRZ is a compact pluggable interface relay designed for use in industrial automation and control systems. It functions as an electrical isolation and switching device between control logic (such as PLC outputs or sensors) and field devices or load circuits. The relay accepts a 24 V AC/DC control signal and switches a separate circuit via its built‑in changeover contact. Its slim profile and DIN‑rail mounting make it suitable for space‑efficient panel installations.
