IRS-C250
Industrial RS-485/422/232 to Fiber Converter
IRS-C250 is a Multi-serial to fiber media converter which adopts RS-232/RS-422/RS-485 triple mode circuits with auto baud rate and direction control. It extends the serial signal link distance to 2KM ( Multi-mode Optical Fiber) or 20KM (Single-mode Optical Fiber) and also provides good immunity of EMI/EMS. To ensure nonstop transmission in hazardous environment, IRS-C250 supports operating temperature-10°~60°C. Further more, IRS-C250 supports Chassis and DIN rail mount for quick and easy installation.
