Product Information
Extended Description
1SVR405621R4000 ABB: The CR-U012DC2 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 12 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.

The CR-U012DC2 features a 12 V DC coil, delivering low control power from PLC outputs while providing robust actuation for two Form C (SPDT) contacts. This enables two independent circuits to be switched from a single control signal, reducing component counts and wiring complexity. The device is designed for DIN rail snap-on mounting with CR-U sockets and circular pin terminals, offering fast installation and straightforward field replacement in crowded control panels. Its 250 V AC / 10 A load rating supports common automation loads, while the IP40 enclosure ensures acceptable protection in typical factory environments. An integrated test button and LED provide intuitive testing and status indication during commissioning and maintenance. Compatibility with standard ABB accessories simplifies expansion and lifecycle management.

FAQs
Install by snapping the CR-U012DC2 into a compatible CR-U socket and mounting the assembly onto a DIN rail. Ensure the 12 V DC coil is connected to the control signal from the PLC or controller. Verify the load connections are within 250 V AC / 10 A, then use the integrated test button for quick commissioning. The circular pin terminals simplify wiring and maintenance, and accessories like holders and markers are available to support organized panels.
The relay provides two SPDT (2 c/o) contacts with a rated operational voltage of 250 V AC and a maximum current of 10 A. The control side uses a 12 V DC coil (U s = 12 V DC). It also supports DC-12 and DC-13 ratings (e.g., 24 V DC switching up to 10 A, 250 V up to 0.1 A in certain modes) and a DC-DC compatibility range suitable for typical automation signals.
Yes. The CR-U012DC2 is listed under CE conformity and UL/CSA documentation, with RoHS compliance per EU Directive 2011/65/EU. It also aligns with CAN/CSA C22.2 No.14 and IEC/EN 61810-1 standards, among others, and benefits from UKCA and other regional certifications as part of the CR-U range.
Ideal for control panels and DIN-rail mounted automation systems that require signal isolation and reliable switching of multiple circuits. Use cases include PLC outputs driving indicators, sensors, or actuators, when compact form factor and easy field replacement reduce downtime. The 12 V DC coil and SPDT outputs enable compact logic interfaces in machine safety circuits and process control panels.
The pluggable design allows quick swaps without de-energizing or rewiring entire modules, reducing maintenance time. An integrated LED and test button aid commissioning and fault finding, while robust circular pin terminals withstand repeated use. Compatibility with standard sockets and accessories minimizes spare parts diversity and supports scalable panel modernization over time.
