OverviewUT-794I industrial PCI-E multiport serial adapter with optic isolation is compatible with RS-422/485 standard, it converts PCI-E signal to balanced differential RS-422/485 signal. With built-in optoelectronic isolator and instant voltage control protector, it is designed to protect RS-422/485 ports; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPERSSOR) instant voltage control. It is with lightning and ESD protection, provides 2, 000V each wire with lightning surge protection, and surge voltage and instant overvoltage protection on circuit which causing by all reasons; the tiny interelectrode capacitance ensures high speed transmission for RS-422/485 ports.
