PCI-E to 4Port 2Port RS-422 RS-485 Adapter Card PCI-E PCI Express Expansion Card
Product Description
PCI Express 4 ports RS422 RS485 Expansion Card PCI-E to RS-422 RS-485 Multi-serial Card Industrial Voltage Suppression Protector product description Industrial grade with transient voltage suppression protector Compatible with RS-422, RS-485 standard, can convert single-ended PCI-E signal to RS-422/RS-485 signal, with fast transient voltage suppression protector, this protector is designed to protect RS- 422/RS-485 interface, using TVS transient voltage suppressor, when both ends of the TVS tube are subjected to an instantaneous high-energy shock, it can reduce the impedance at both ends of the TVS tube at a higher speed, absorb a large current, and thereby reduce its voltage. The voltage across both ends is clamped at a predetermined value to protect subsequent circuit components from damage due to transient high voltage surges. This protector can effectively suppress lightning and ESD, provide 600W lightning surge protection power per line, as well as surge voltage and transient overvoltage generated on the line due to various reasons, and the small inter-electrode capacitance ensures that RS-422 /RS-485 connection high-speed transmission. Package include: 1xPCIe to 4Port/2Port RS-422 RS-485 Adapter Card PCI-E PCI Express Expansion Card Protector
