Entry-level industrial 10/100BaseT(X) to 100BaseFX media converters
The IMC-21 industrial media converters are entry-level 
10/100BaseT(X) to 100BaseFX media converters designed to provide 
reliable and stable operation in harsh industrial environments. The 
converters are a cost-effective solution that run on either a 12 to 
45 VDC power input or 18 to 30 VAC power input, and can operate 
reliably in temperatures ranging from -10 to 60°C. The rugged 
hardware design ensures that your Ethernet equipment can withstand 
demanding industrial conditions. The IMC-21 converters are easy to 
mount on a DIN-Rail or in distribution boxes.
