Product Information
Extended Description
1SVR405621R8100 ABB: The CR-U110DC2L 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. 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
Install the CR-U110DC2L by snapping it onto the CR-U socket and placing the socket onto a standard DIN rail. Ensure the 110 V DC control circuit is correctly wired to the coil terminals and verify the 250 V AC / 10 A SPDT output rating matches the load. The built-in test button aids commissioning, while the LED signals coil energization during operation.
2 c/o SPDT outputs provide two form C contacts per relay, enabling simultaneous switching of two circuits from a single input. This supports diverse control schemes, such as driving two loads or creating interlocks. The ratings of 250 V AC and 10 A accommodate common automation loads, improving design flexibility and reducing component count.
Yes. The CR-U110DC2L is designed for plug-in compatibility with standard CR-U sockets, allowing quick field swaps and straightforward maintenance. You can pair it with standard sockets, logic sockets, and pluggable function modules, plus holders and markers, to build a modular and scalable control solution with minimal downtime.
The relay carries CE and UL 508 certifications, with CSA/UR compatibility and additional declarations, matching many global electrical safety requirements. IP40 protection provides enclosure safety, while the device’s compliance with CAN/CSA, IEC/EN standards and UKCA/CE declarations supports global deployment in compliant control systems.
The pluggable design enables fast field replacement without rewiring, reducing downtime and maintenance labor. Built-in LED and test button simplify commissioning and fault finding, lowering commissioning time and spare-parts waste. Over time, this translates to a lower total cost of ownership and improved plant availability for panel builders and system integrators.
