Hardware interface

Connection type: DR44 female x 1

Bus: 32 bit universal PCI

Transmission rate: 300bps-921.6Kbps

UT-764I opto-isolated PCI converter card is compatible with RS-232 standards, and is able to convert PCI signals into balanced differential RS-232 signal. The built-in opto-isolator provides isolation voltages up to 2500Vrms. It is also equipped with a high-speed transient voltage suppressing protector, which is designed to protect the RS-232 interface. The state-of-the-art TVS, Transient Voltage Suppressor, is being used in the system.

Under normal circumstances, the TVS tube remains in high-impedance status. When two ends of the TVS tube receive transient high energy impact, it reduces the impedance at both ends in an extremely rapid manner to absorb the huge amount of current. Furthermore, it suppresses voltage at both ends to a preprogrammed value to protect circuit components from damages caused by transient high voltage impacts. The protector can effectively suppress lightning and ESD. It also provides 600W of lightning surge protector power for every line, and protections against surge voltage and transient overvoltage caused by any other factors. It also guarantees the high-speed transmission of RS-232 interfaces with extremely small capacitance.

Applications:

UT-764I is widely used in industrial automation system manufacturing and system integration.
