描述

The 2891029 is an unmanaged industrial Ethernet switch designed for reliable network communication. It provides four RJ45 ports that support 10/100 Mbps transmission speeds with autonegotiation and autocrossing, plus one SC-D single-mode fiber optic port for 100 Mbps full-duplex communication. The fiber optic interface supports long-distance connections up to 25 km with a wavelength of 1310 nm. Housed in a compact aluminum enclosure for DIN rail mounting, it operates on a supply voltage from 12 V DC to 48 V DC and within a temperature range of -10 °C to 60 °C. Features like store-and-forward switching and LED diagnostics for link and activity status make it a simple and effective solution for expanding industrial networks in star or linear topologies.
