Fiber Optical Modem


Model HY-11-28 is a sort of more function and economy HY-11-RS-485/RS-422 interface optic fiber

MODEM. It is the best choice to connect RTU to HOST or SCADA controller. It used

Optic fiber as transfer medium, increase the transfer function of system. Communication equipment abstain menace effective to lightning strike, surge, electromagnetism disturb under the scurviness environment.
