FAQs
Installation starts with treating the CR-MX024AC4LT as a plug-in module. Align the flat-pin terminals with the socket, press firmly to seat the module, and secure it in the panel using standard mounting practices. The pluggable design allows quick replacement in case of failure, minimizing downtime and facilitating fast field service.
The unit uses a 24 V AC control coil and provides 4 c/o SPDT contacts rated up to 250 V AC at 5 A. Coil-to-contact isolation is rated at 1.5 kV, with operation supported across 50/60 Hz. This makes it suitable for common control circuits while maintaining safety margins in industrial environments.
Yes. It operates from -40 to +70 °C and has IP40 protection. It aligns with CE, TÜV, UL/CSA certifications, and is supported by CQC documentation, which helps meet regulatory requirements across European and North American markets for industrial automation equipment.
This relay is ideal for compact control panels in factory automation, packaging lines, conveyors, and small process control systems. Its 4 SPDT outputs, modular pluggable design, and diagnostic LED with a test button support quick commissioning, easy maintenance, and scalable panel architectures for OEMs and integrators.
Maintenance benefits come from its pluggable architecture, which reduces downtime during replacement and simplifies spare-part stocking. The built-in LED and test button assist rapid fault localization, while compatibility with standard sockets and CAD resources speeds integration. Over time, this translates to lower service costs and faster time-to-market for automation projects.
