FAQs
Install the CR-MX024AC4 into compatible CR-MX sockets using the flat-pin connections. Ensure the coil is driven with 24 V AC and connect the SPDT outputs to the corresponding relay circuits (common, normally open, normally closed). Use standard mounting provisions and accessories for the chosen socket system. This modular approach enables quick field replacement without disturbing other circuitry.
The relay operates from a 24 V AC control supply. It provides 4 c/o SPDT contacts with a rated operational voltage of up to 250 V AC and a maximum switching current of 5 A. Impulse withstand between coil and contacts is 1.5 kV, and insulation voltage is rated at 250 V, supporting safe operation in standard industrial control circuits.
Yes, it is designed for industrial environments with an ambient operating range of -40 to +70 °C and an IP40 enclosure rating. This makes it suitable for factory floors and control panels where robust switching and reliable signaling are required, while maintaining safe operation and impedance to common electrical noise in automation systems.
The relay carries CE, UL/CSA, and TÜV certifications, reflecting compliance with European, North American, and safety standards. These certifications help meet regulatory requirements for equipment used in global manufacturing, facilitate safer product integration, and streamline customer audits and supplier qualification processes.
A pluggable design minimizes downtime by enabling rapid replacement of function modules while the rest of the control system remains intact. Standard sockets and accessories simplify spare parts management, reduce maintenance hours, and lower total cost of ownership. For panel builders, this translates to faster commissioning and easier lifecycle management of automation projects.
