UT-794I, 4-port PCI-E to RS485 / RS422 multi-port Serial Card with Ptoelectronic Isolation

UT-794I, industrial grade PCI-E converter, can convert single-end PCI-E signal to balanced differential RS-485/RS-422 signal with built-in photoelectric isolation and TVS. Integrated with 600W lightning surge protection for each line and ESD protection, UT-794I protects your device against surge voltage and transient overvoltage caused by any other factors. It also guarantees the high-speed transmission of RS-422/RS-485 interface.

Applications:

UT-794I is widely used in industrial automation system manufacturing and system integration.
