N-TRON 900B-908TX Industrial Ethernet Switch System

The N-Tron 900B-908TX Industrial Ethernet Switch System is a modular, rugged 8‑port Ethernet switch that combines a 900B chassis with the 908TX expansion module to provide eight 10/100BaseTX RJ45 ports for reliable industrial networking. The 900B chassis supports up to three interchangeable expansion modules, enabling scalable deployments in factory networks, control cabinets, and process lines. The 908TX module delivers eight auto‑negotiating 10/100 Mbps ports over Category 5 twisted‑pair cabling and supports Auto‑MDI/MDIX with IEEE 802.3/802.3u standards. Power is supplied to the system via 10–30 VDC redundant inputs. Built for harsh environments, it features a rugged industrial steel enclosure with DIN rail mounting and an operating temperature range of −20°C to 70°C. The unit offers plug‑and‑play unmanaged operation and modular expansion capability, with model‑dependent UL Listed Class I Division 2 hazardous location ratings. It is commonly used in PLC networks, industrial PCs, Ethernet I/O, machine automation, CNC systems, robotics, and other production equipment requiring reliable, scalable Ethernet connectivity.
