Product Description:
Danfoss provides the MCA 121 Cable and Accessory for industrial network integration. The product provides stable data transfer in automated environments. It supports efficient communication within multiple drive systems. Dependability in automation is reinforced by consistent diagnostic visibility. The designation MCA 121 signifies the product 130B1119 in the series.
The MCA 121 cable and accessory has a gross weight of 0.633 kg which supports stable handling during installation in compact enclosures. The net weight is 0.51 kilograms. Reduced component mass decreases mechanical load on mounting structures and allows simplified integration in multi-card assemblies. The physical volume is 5.46 liters. This dimensional volume impacts placement flexibility within confined industrial cabinets. The unit includes two RJ45 Ethernet ports. Dual-port configuration provides redundant access paths or line extension in larger drive networks. The supported topologies are line, star and ring. Such variety allows adaptation to both small isolated systems and extended distributed networks. The transmission speed is 10/100 Mbps full duplex. Full duplex communication reduces packet collisions and maintains predictable data flow during concurrent transmission and reception. Diagnostic attributes are built-in with LED indicators. The real-time status signals allow technicians to verify connectivity and detect faults during active operation.
The MCA 121 cable and accessory uses standard shielded RJ45 connectors which reduce electromagnetic interference and maintain integrity in industrial electrical environments. The network conformity includes standard Ethernet switches and EtherNet/IP networks. Such compliance provides interoperability with existing automation infrastructures. The power supply is drawn directly from the host drive. Dependence on the host eliminates the requirement for an external power unit and reduces wiring complexity. The mounting is designed as a plug-in option card for drive controllers. This arrangement provides secure integration without additional mechanical supports.
Frequently Asked Questions about MCA 121:
Q: How does the MCA 121 Danfoss Cable and Accessory enhance industrial networking?
