SUPCON SUP-2119M Industrial Ethernet Switch Module

Product Overview

The SUP-2119M industrial Ethernet switch from SUPCON is designed to deliver dependable Layer-2 network connectivity in control rooms, substations, and industrial network cabinets. It is equipped with sixteen 10/100 Mbps adaptive copper Ethernet interfaces and supports optional fiber uplink modules for extended communication distances.

Built for long-term deployment, the switch emphasizes electrical stability, predictable forwarding behavior, and maintenance-free operation. Its unmanaged architecture allows fast commissioning without configuration software, making it suitable for fixed industrial networks where reliability is prioritized over dynamic network control.

Core Capabilities and Operational Advantages

The SUP-2119M automatically negotiates link speed and duplex mode, enabling seamless interoperability with both legacy and newer Ethernet devices. A store-and-forward switching mechanism verifies frame integrity before transmission, reducing error propagation across the network.

Traffic stability is enhanced through broadcast storm suppression and IEEE 802.3x flow control, ensuring reliable operation even under high data loads. Optional single-mode or multimode fiber interfaces provide long-distance uplinks between buildings, workshops, or network zones while maintaining signal accuracy.

The rack-mount metal enclosure supports continuous operation in electrically noisy industrial environments.
