The Moxa EDS-205A-M-ST-T is a 5-port wide-temp unmanaged industrial Ethernet switch - 4x copper + 1x 100BaseFX multi-mode (ST) reaching 5 km. Aluminium IP30, DIN-rail, -40 to 75 deg C. ATEX / DNV / LR / ABS / NK / EN 50121-4 / NEMA TS2 certified.
The Moxa EDS-205A-M-ST-T is a 5-port unmanaged industrial Ethernet switch in the EDS-205A Series, with four 10/100BaseT(X) RJ45 copper ports and one 100BaseFX multi-mode (ST) fibre port reaching 5 km. Built for harsh industrial, maritime, and rail deployments, the switch features an aluminium IP30 housing, DIP-switchable Quality of Service and Broadcast Storm Protection, and a comprehensive certifications stack spanning hazardous locations (ATEX, IECEx, Class I Division 2), maritime (DNV, LR, ABS, NK), rail (EN 50121-4), and traffic control (NEMA TS2). The wide-temperature -40 to 75 deg C rating suits outdoor enclosures, rail wayside applications, maritime deployments, and harsh industrial environments.
