Product Information
Extended Description
1SVR405621R1000 ABB: The CR-U024DC2 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
The 1SVR405621R1000 is a pluggable CR-U relay designed to fit CR-U sockets and snap onto a DIN rail. It uses circular pin terminals for secure connection and can be combined with standard sockets, logic sockets, and holders, enabling seamless upgrades without rewiring. Ensure the socket is the CR-U family and that mounting space on the DIN rail is unobstructed for reliable insertion.
This relay operates with a 24 V DC control supply and provides 2 c/o SPDT outputs rated up to 250 V AC / 10 A. When using DC-12 and DC-13 ratings, it supports (230 V) 1.5–10 A depending on input. The insulation voltage is 250 V, and the device is IP40 protected, which informs safe operating envelopes and installation clearances in control panels.
Yes. The CR-U range is certified for UL/CSA and CE (EU Declaration of Conformity) with additional UKCA and RoHS compliance. This makes the relay appropriate for regulated industrial environments, machine controls, and OEM equipment, ensuring regulatory alignment across multiple regions.
The relay includes a built-in test button and an LED indicator to verify energization and status quickly during commissioning and maintenance. The plug-in design allows fast replacement, minimizing service interruptions, while DIN-rail mounting and standard accessories simplify diagnostics and spare-part management.
Using pluggable CR-U relays reduces wiring complexity and speeds replacement, cutting labor time during maintenance by enabling quick swaps. The combination of 24 V DC control, SPDT outputs, and robust IP40 protection translates to lower downtime, faster commissioning, and extended panel life, delivering tangible cost savings over traditional fixed-relay solutions.
