110 V DC coil with 2 c/o SPDT outputs enables direct control of loads up to 250 V AC at 7 A, reducing control hardware counts and simplifying panel design. This translates to lower bill of materials and faster commissioning for assembly lines and packaging machines. The plug-in CR-MX interface supports quick module swaps, cutting maintenance time and minimizing production downtime in critical equipment fleets. An integrated LED and a blue test button provide immediate status indication and manual actuation, accelerating fault isolation during startup and routine service without rewiring. Flat-pin connections and compatibility with standard sockets improve installation speed and reduce installation errors, while the compact footprint (21.5 mm width, 37 mm height) fits tight control cabinets. Protection rating IP40 and RoHS compliance help meet industrial environments and sustainability goals. Certifications (CE, UL/CSA, TÜV) strengthen regulatory confidence for global deployments, supporting scalable modernization programs across multiple factories.

FAQs
CR-MX110DC2LT installs by plugging into compatible CR-MX sockets using flat-pin connections. Remove the existing module, align the relay, and press firmly until seated. The compact footprint—21.5 mm wide, 37 mm high—fits tight control panels, while the IP40 enclosure protects against dust ingress. Ensure a 110 V DC control supply and a 250 V AC / 7 A load within rated limits.
Key specs include a 110 V DC rated control coil and 250 V AC output with 7 A contact current. It provides 2 c/o SPDT contacts, flat-pin terminals, and a 1.5 kV coil-to-contact impulse withstand voltage. On the AC side, it supports up to 7 A at 230 V and offers reliable DC-12 and DC-13 performance per datasheet.
Best suited for automation panels in manufacturing, packaging lines, and machine control cabinets, the CR-MX110DC2LT provides robust isolation and fast module replacement. Its miniature footprint and plug-in design support scalable rack systems and standardized sockets in pharmaceutical, food-and-beverage, and automotive assembly environments. The integrated LED and test button speed commissioning and fault diagnosis, reducing downtime during changeovers.
ABB's CR-MX110DC2LT carries CE and UL/CSA certifications, TÜV approval, and a CQC certificate, with RoHS compliance under EU directives.
