Product Information
Extended Description
1SVR405621R6000 ABB: The CR-U048DC2 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 48 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. Standard sockets, logical sockets, pluggable function modules, holder and marker are available as accessories.

FAQs
Installing the CR-U048DC2 is straightforward: it plugs into a compatible CR-U socket and mounts on a standard DIN rail for snap-on installation. Ensure the coil is powered at 48 V DC (A1-A2) and connect the two SPDT outputs to the load. The device features robust circular pin terminals for secure wiring.
Electrical ratings include a 48 V DC control supply, 250 V AC maximum operating voltage, and 10 A output per SPDT contact. The DC-12 rating shows 24 V loads up to 10 A, while DC-13 limits are 2 A at 24 V or 0.1 A at 250 V. The relay supports IP40 protection and UL/CSA and CE compliance.
Commonly used in machine control and automated panels, the CR-U048DC2 enables safe, modular switching of multiple circuits from a single control input. Its plug-in architecture simplifies field upgrades and spare-part replacement, minimizing downtime. For testing and commissioning, the integrated test button and LED indicator speed validation and provide immediate feedback during startup.
Certification coverage includes UL 508, CAN/CSA C22.2 No. 14, CE, UKCA, RoHS compliance, CCC, CQC, EAC, UR, and VDE recognition. This broad compliance supports safe procurement for global automation projects, ensures traceability of components, and reduces supplier risk when specifying relays for safety and control circuits in industrial environments. Compatibility with international standards helps verify conformity across regions.
From a maintenance and ROI perspective, the CR-U series reduces downtime with modular, plug-in design and an integrated test button. Availability of compatible sockets and markers simplifies expansion and spare parts stocking. In practice, simple field replacement lowers service costs, while clear status indication supports faster fault isolation and reduced mean time to repair.
