Introduction
Model277/A is one kind can offer RS-232 serial port carry transparent optic fiber modem of transmission to get end to user, it is the best choice to connect RTU to HOST or SCADA controller. Model277/A adopt optic fiber transmit, have isolate protection, data privacy is fine, working steady, data, such threats to communication equipment as the wave is welled up and interfered with electromagnetically that the effective one has prevented the abominable environment from being struck by lightning, can work in the abominable and dangerous environment reliably.
Can be used in occasions such as various industrial control, course controlling, traffic controlling and intellectual district , especially suit the bank, electricity and interfering with environment department and system with the special requirement electromagnetically.
