The 1241000000 is an unmanaged, plug-and-play Fast Ethernet switch designed for industrial network infrastructures. It provides 16 10/100BaseT(X) RJ45 ports that support auto-negotiation, full/half-duplex mode, and auto MDI/MDI-X. The device operates on a wide supply voltage range from 9.6 to 60 V DC, featuring dual redundant inputs and reverse polarity protection for enhanced reliability. Housed in a rugged, IP30-rated metal enclosure for rail mounting, it is built to withstand industrial environments with an operating temperature of 0 °C to 60 °C. Key features include a DIP switch for broadcast storm protection, a 4K MAC address table, and a fault-signaling relay output, making it a robust solution for expanding industrial Ethernet networks.
