The unit includes an integrated LED indicator and a manual test button, simplifying commissioning and troubleshooting. It mounts easily on a standard DIN rail and works with CR-U sockets, logic sockets, and modular accessories, reducing spare parts while boosting maintenance efficiency. Engineers gain predictable performance, faster testing, and easier future expansion, translating into lower lifecycle costs and improved system uptime.
Product Information
Extended Description
1SVR405621R8400 ABB: The CR-U110DC2LD 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 110 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
This relay is designed for DIN rail installation and uses CR-U sockets and modular accessories. Ensure a 110 V DC control signal is available, connect the two SPDT outputs to their respective loads with proper isolation, and verify the IP40-rated enclosure is maintained. Use the built-in test button during commissioning to verify operation before full load energization.
Key ratings include a 110 V DC rated control voltage, 2 c/o SPDT contacts, and output capability of 250 V at up to 10 A. Insulation voltage is 250 V, with DC-12 ratings of 24 V at 10 A and DC-13 ratings of 24 V at 2 A (or 250 V at 0.1 A). The device supports UL 508 and CE/CSA compliance with IP40 protection.
Yes. The CR-U family is UL 508 listed and includes CE/UKCA declarations, meeting essential electrical safety and performance standards for industrial control panels. Its IP40 rating and -40 to +70 °C operating range further support compliant deployment in diverse factory environments.
The CR-U relay is designed to snap into CR-U sockets and is compatible with standard logic sockets, pluggable function modules, holders, and markers. This streamlines upgrades and replacements, reduces wiring complexity, and minimizes panel real estate requirements during installation.
The built-in LED aids quick energization checks, the test button speeds commissioning, and its robust DIN-rail mounting reduces installation time. With reliable SPDT outputs and surge protection, coil failures and mis-wiring are minimized, leading to lower maintenance costs, reduced downtime, and faster project delivery in automation environments.
