JetCon 2401 is a 1-port RS232/422/485 serial to fiber media converter with extended fiber transmission. Single-mode and Multi-mode fiber optic ports meet your needs for long-distance transmission up to 40KM. JetCon 2401 will automatically detect the data baud rate of the connected full-duplex the serial device, ranging from 300 to 921,600bps. By moving up the DIP switch, JetCon 2401 supports an auto setting function without system power reset to change the serial interface, fiber wiring architecture, and termination of receiver and transmission line. Also, JetCon 2401 is specially designed for applications requiring good immunity of EMI/EMS such as power substation, rail and traffic control signification systems under severe electromagnetic interference and wide temperature range.

JetCon 2401 can be easily wall mounted as well as be mounted directly on DIN rail. AC 24V(12~32V) or DC 24V(12~48V) is available for different operating environments. With IP 30 rigid aluminum case, CE/FCC regulatory approvals, and 5-year global warranty, JetCon 2401 is your reliable choice for hazardous applications.

You can place an order for the Beijer JetCon 2401 RS232/422/485 to fiber serial converter online via one of our Middle East branches (Dubai/ Oman/Saudi Arabia) and get it delivered at a low cost at a specific time.
