CR-S024VADC1CRZ

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.

Key Features Single‑pole changeover output (SPDT) for versatile switching functions. Compatible with 24 V AC/DC control voltage for flexible control inputs. Compact design for DIN‑rail mounting in control panels. Spring terminals for secure and reliable electrical connections. Clear mechanical separation of control and load circuits for safety. Slim width saves space in automation cabinets. Electrical Ratings Rated Control Supply Voltage: 24 V AC or DC (control coil). Output Contact Configuration: 1 changeover (1 C/O / SPDT). Rated Output Voltage: Up to 250 V AC. Rated Current: 6 A at 250 V AC. Operational Current Categories: AC‑12: ~6 A at 230 V AC DC‑12: ~6 A at 24 V DC DC‑13: ~1 A at 24 V DC (for inductive loads). Electrical Isolation: Full isolation between control input and switched output. Mechanical & Installation Terminal Type: Spring‑loaded terminals for flexible and rigid conductors (up to ~2.5 mm² / 14 AWG). Mounting: DIN‑rail (TH35‑7.5) clip‑on installation for quick panel setup. Wire Stripping Length: ~7 mm. Tightening Torque: Approx. 0.5 N·m for terminal screws. Protection Rating at Terminals: IP20 touch protection when installed in enclosure. Environmental Operating Temperature Range: Approximately –40 °C to +70 °C ambient. Storage Temperature Range: Moderate storage range suitable for warehouse conditions. Designed for industrial environments where temperature and vibration vary within standard control panel ratings. Physical Dimensions Width: Approx. 6.2 mm — very slim module. Height: Approx. 76.6 mm. Depth (Length): Approx. 94.7 mm. Weight: Around 0.03 kg — lightweight and compact. Typical Applications Electrical isolation and amplification between control logic and field devices. Switching control signals to actuators, indicators, contactors, or other loads. Panel‑mounted automation systems where board space is limited. Control circuits requiring small footprint relays with reliable switching.
