Product Description:

UT-209 optical isolation repeater, compatible with RS-422, RS-485 standard, can extend the communication distance of RS-422/RS-485 bus network, increasing the number of RS-422/RS-485 network equipment within set opto-isolator and DC / DC isolation module, capable of providing up to 2500Vrms isolation voltage interfaces at both ends with a fast transient voltage suppression protector, this protection is designed to protect RS-422/RS-485 interface TVS tube, TVS (TRANSIENT VOLTAGE SUPPRESSOR) using today's advanced transient voltage suppressor, under normal circumstances, a high-impedance state when TVS tube ends to withstand high instantaneous energy impact, it can be an extremely high speed two The end of the impedance is reduced, the absorption of a large current, so that the voltage across it is clamped at a predetermined value, and to protect the back of the circuit element is not damaged due to transient high pressure shock. This protection can effectively inhibit lightning (LIGHTNING) and ESD, lightning surge protection power line 600W, and for various reasons on the line generated surge voltage and transient overvoltage and electrode capacitance to ensure minimal RS-422/RS-485 interface high-speed transmission. RS-422, RS-485 input terminal connected via DB9 female connector. RS-422, RS-485 output terminals connected via DB9 male connectors. Converter with internal zero delay automatic transceiver conversion, unique I / O circuit automatically controls the data flow direction, without any handshaking signals (such as RTS, DTR, etc.), without the jumper settings to achieve full-duplex (RS- 422), half-duplex (RS-485) mode conversion, plug-and-play. 
UT-209 optical isolation interface converter for point-to-point and point-to-multipoint communications provide a reliable connection, point-to-multipoint each repeater can be allowed to connect 128 RS-422 or RS-485 interface device, data communication speed 300-115.2KBPS, with a power indicator and data flow indicator can indicate malfunction.
