UT-211 is a RS-232 serial port optoelectronic isolator. It adopts advanced optoelectronic isolation technology, maximally protects RS-232 serial interface devices from bad environment damage, such as ground loop circuit voltage, surge, lightning, ESD, hot-plug and electromagnetic interference, etc. The damage of RS-232 port is related to communication hardware. The reasons 90% are converged on above mentioned. For example, device A connects device B with RS-232 port, if the voltage difference of ground line between A and B is up to 50V (usually up to 80V), RS-232 port will not working normal; the isolated voltage of RS-232 port will reach 2,500Vrms instantly, together with 500VDC continuous peak voltage difference; it also absorbs in ESD and electromagnetic interference, so as to protect RS-232 port. The optoelectronic isolation technology is fully isolating the electrical devices and ground loop circuit on both ends; it converts the electrical signal to optic signal, then transmits the signal to another end, finally converts it back to electrical signal. This protects the communication device from ground loop circuit and surge interference, which greatly improve the reliability and stability of the communication system. UT-211 gets widely application in point to point RS-232 communication system, UNIX multi-user system, monitoring system, and ATM for power, insurance, telecommunications, railway, post office, finance, banking, securities and program control, etc.
