DB9 RS-232 5 Bits Optoelectronic Isolated Converter 2,500Vrms

Description

The GM-1015-B is an RS-232 serial port optoelectronic isolator. It adopts advanced optoelectronic isolation technology, prevents RS-232 serial interface device damage from a bad environment, such as ground loop circuit voltage, surge, lightning, ESD, hot-plug and electromagnetic interference, etc. The damage of the RS-232 port is related to communication hardware. For example, device A connects device B with an 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 work normally; 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 an electrical signal. This protects the communication device from a ground loop circuit and any surge interference, which greatly improves the reliability and stability of the communication system.

The GM-1015-B finds application in point to point RS-232 communication systems, UNIX multi-user systems, monitoring systems, and ATMs for power, insurance, telecommunications, railway, post office, finance, banking, securities and program control, etc.
