UOTEK Industrial 4 Port PCI-E to RS485/422 Multi Serial Card PCIE to RS-485 RS-422 PC Serial Expansion Card with Serial Cable 9-pin Com Port with DR44 Female UT-794

Overview ●UT-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.
