The Moxa IMC-21A-S-SC-T is an entry-level industrial 10/100BaseT(X) to 100BaseFX media converter designed for harsh industrial environments. It features one copper RJ45 port and one single-mode SC fiber port supporting distances up to 40 km at 1310 nm wavelength. The "-T" suffix indicates the extended temperature model, operating from -40 to 75°C. Housed in a metal IP30-rated enclosure with DIN-rail mounting, it supports 12-48 VDC redundant power input with reverse polarity protection. Key features include Link Fault Pass-Through (LFPT) for remote fault notification, DIP switches for FDX/HDX and 10/100M configuration, and 1.5 kV built-in magnetic isolation. The compact dimensions of 30 × 125 × 79 mm and lightweight 170 g design make it ideal for space-constrained industrial installations. Typical applications include factory automation, SCADA networks, transportation systems, and power utility communications.
Q: What is the maximum fiber distance for the IMC-21A-S-SC-T?
The single-mode SC fiber port supports distances up to 40 km at 1310 nm wavelength.
Q: What does the "-T" suffix mean?
The "-T" indicates the extended temperature model, rated for operation from -40 to 75°C, suitable for outdoor and harsh environments.
Q: What power supply does the media converter require?
It accepts 12 to 48 VDC with a removable 3-contact terminal block, with reverse polarity protection and 1.1 A overload current protection.
Q: Can this converter be DIN-rail mounted?
