Quick Summary
CR-U024AC2 pluggable interface relay is a universal signaling device for DIN-rail control panels. Engineers struggle with maintenance and testing of pre-wired relays in tight panel spaces. This ABB module carries CE and UKCA declarations, UL/CSA certification, RoHS compliance, and an IP40 rating for rugged industrial environments. By delivering a 24 V AC control input with two SPDT outputs and easy plug-in replacement, it reduces downtime and spare-parts complexity while supporting modular automation and efficient panel design. That combination of reliability, fast deployment, and accessible accessories supports faster time-to-value for machine builders and system integrators.
Product Information
Extended Description
1SVR405621R0000 ABB: The CR-U024AC2 pluggable interface relay is a univeral relay and is also commonly referred to as an ice cube relay. CR-U relays may be plugged into CR-U sockets and this combination of relay and socket may be seemlessly snap-on mounted onto a DIN Rail. CR-U relays have robust circular pin terminals, designed and manufactured to handle tough, repetitive-use applications and are more durable than standard relays.This relay operates with a 24 V AC rated control supply voltage and has a 2 c/o (SPDT) output with contacts rated at 250 V / 10 A, enabling the possibility of switching multiple circuits with a single input signal. The relay has an integrated test button which is used for the manual actuation of the relay by locking it's output contacts. The test button facilitates easy testing and commissioning. The relay also has an integrated LED, which provides the visual indication of the energization of the relay coil. Standard sockets, logic sockets, pluggable function modules, holders and markers are available as accessories.

FAQs
The CR-U024AC2 is a pluggable interface relay with two SPDT outputs driven by a 24 V AC coil, designed for DIN rail mounting. It is ideal for modular control panels, signaling circuits, and interlock logic where quick replacement and compact form factor reduce maintenance time and space requirements.
Install by snapping the relay into a CR-U socket mounted on the DIN rail. Connect the 24 V AC control to A1-A2 and wire the two SPDT outputs to the respective load circuits, observing 250 V AC at up to 10 A. The circular pin terminals provide robust connections suitable for vibration and frequent switching.
The relay is rated for DC-12 loads up to 10 A at 24 V (IE) and DC-13 ratings of 2 A at 24 V or 0.1 A at 250 V. For high-current DC switching, ensure your load is within these ratings and consider derating factors and contact wear in continuous DC service.
The device complies with CE and UKCA declarations, UL/CSA certifications, and RoHS conformity. It also carries EAC and VDE recognitions and is tested to CAN/CSA C22.2 No. 14, IEC/EN 61810-1, and UL 508. This broad certification supports global procurement and regulatory adherence.
An integrated test button and LED indicator provide immediate feedback on energization and contact status, simplifying commissioning and troubleshooting. This feature reduces commissioning time and helps technicians verify proper operation without external test equipment.
