4 Port RS232 USB 2.0 to Serial Adapter with Optical isolation - Surge Protection

Optical isolation and surge protection are available on serial port and is individually optically isolated with 2000 volt DC optical isolation on 8 signal pins, GND is isolated by 5V DC-to-DC converter. (GND cannot be isolated by photo-coupler.) meets the high level of optical isolation. The optical isolation protects your computer from spikes and surges, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse.
