Product Information
Extended Description
1SVR405621R1100 ABB: The CR-U024DC2L 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 DC 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
Install the CR-U024DC2L by plugging it into a compatible CR-U socket and snapping the assembly onto a DIN rail in the control cabinet. Wire the 24 V DC coil to the control supply on A1-A2, and connect the two SPDT outputs to the respective load circuits. Use the built-in test button to verify operation and rely on the LED indicator for energization status during commissioning.
The coil is 24 V DC. The relay provides two SPDT outputs with a voltage rating up to 250 V AC and a switching current of up to 10 A. DC-12 ratings are 10 A at 24 V, while DC-13 ratings are 2 A at 24 V or 0.1 A at 250 V. These specs enable reliable control of multiple circuits from a single input signal.
Yes. The device complies with CE, UL/CSA, and UKCA declarations, along with RoHS compliance. It carries IP40 protection, making it appropriate for cabinet interiors and protected assemblies. Its standards alignment with IEC/EN 61810-1 and UL 508 supports safe use in industrial control panels and machinery.
Ideal for machine control panels, sensing-to-actuation interfaces, and general control circuits requiring quick replacement and reliable SPDT switching. The 24 V DC coil is common in PLC and relay logic circuits, while the 2 c/o outputs enable multiplexed control from a single input, improving panel density and reducing wiring complexity.
Consider using standard CR-U sockets, logic sockets, and pluggable function modules to maximize flexibility and ease of maintenance. Accessories like holders and markers simplify panel layout, and CAD drawings support accurate design. The relay is designed to be compatible with the DIN-rail ecosystem for fast deployment and scalable automation.
