Product Information
Extended Description
1SVR405621R4400 ABB: The CR-U012DC2LD 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, and a diode, for surge suppression. Standard sockets, logic sockets, pluggable function modules, holders and markers are available as accessories.

FAQs
Install the CR-U012DC2LD by pulling the matching CR-U socket onto the DIN rail, then snap the relay into the socket. The circular pin terminals provide secure, vibration-resistant connections. This modular approach allows quick replacement without rewiring, reducing downtime during commissioning and field maintenance.
The relay uses a 12 V DC control coil and provides 2 c/o SPDT contacts. It can switch up to 250 V AC at 10 A, with rated currents of AC-12 (230 V, 10 A) and DC-12 (24 V, 10 A). The device includes a diode for surge suppression and an integrated LED to indicate energization.
Yes. The module is CE and UKCA declared, with UL/CSA approvals and RoHS compliance. These certifications support compliance across Europe, the UK, and North American markets, simplifying cross-border deployments and supplier audits for industrial projects.
Yes. The 2 c/o SPDT outputs allow one input signal to switch two separate circuits, enabling efficient control schemes in automation panels. This is particularly useful for signaling, interlocks, or interdependent loads in machine automation.
The pluggable design and DIN-rail mounting simplify sourcing and stocking of spare parts, reducing field inventory. Built-in LED and test button streamline commissioning and testing, while the robust terminals withstand high-cycle applications. The compact size also frees panel space, enabling more efficient enclosure layouts and easier compliance documentation.
