The device carries CE, UL/CSA, and UKCA certifications and is rated IP40, enabling safe DIN-rail operation in demanding environments. With 48 V AC control and 2 SPDT contacts rated up to 250 V/10 A, it delivers flexible logic and scalable panel design for automation and machine control. The pluggable design supports CR-U sockets for modular replacement, reducing spares and maintenance time and improving overall equipment uptime.
Product Information
Extended Description
1SVR405621R5000 ABB: The CR-U048AC2 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 48 V AC 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.
