Bortivier 1 PCS PCI Expansion 4 Ports RS422 RS485 Expansion Card PCI-E to -422-485 Multi-Serial Card PC+Metal

Compatible with -422, -485 standard, can convert single-ended PCI-E signal to -422/-485 signal, with fast transient voltage suppression protector, this protector is designed to protect - 422/-485 interface, using transient voltage suppressor, when both ends of the tube are subjected to an instantaneous high- shock, it can reduce the impedance at both ends of the 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. Industrial grade with transient voltage suppression protector This protector can effectively suppress ESD, provide 600W surge protection power per line, as well as surge voltage and transient overvoltage generated on due to various reasons, and the small -electrode capacitance ensures that -422 /-485 connection high-speed transmission.
