Schneider Electric 499NES18100 Connexium Ethernet Switch

Schneider Electric's Connexium 499NES18100 unmanaged Ethernet switch provides eight 10/100Base-TX RJ-45 ports for reliable communication between PLCs, HMIs, industrial controllers, I/O devices, and other Ethernet-enabled automation equipment in control panels, manufacturing systems, and process automation equipment. It uses CAT5e shielded copper and supports Ethernet TCP/IP (IEEE 802.3/IEEE 802.3u) with store-and-forward switching and a maximum cable length of 100 m per port. The unit operates from 24 VDC (18–32 VDC SELV), draws about 7 W, features dual redundant power inputs, a volt-free fault contact (1 A max), 35 mm DIN-rail mounting, IP20 protection, CE certification, and an operating temperature range of 0–60°C. As part of the CONNEXIUM family, it is commonly used in PLC networks, HMI connectivity, SCADA, distributed I/O networks, conveyor controls, packaging machinery, process automation, manufacturing cells, and material handling systems where dependable Ethernet communication is essential.
