Product Description:

UT-208 optical isolation interface converter compatible with RS-232C, RS-422, RS-485 standard, able to single-ended RS-232 signals are converted to balanced differential RS-422 or RS-485 signal, the built-in photoelectric isolation, can provide up to 2500Vrms isolation voltage, with fast transient voltage suppression protector, this protection is designed to protect the RS-422/RS-485 interface, using today's advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) instantaneous TVS tube state voltage suppressor, under normal circumstances, in a high-impedance state, when the TVS tube ends is subjected to instantaneous high energy impact, high speed can be the impedance across the decreased absorption of a large current, thereby both ends of the voltage 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-232 interface port via a DB9 female connector is compatible with standard RS-232C interface connected to the RS-422, RS-485 side through DB9 male connector connected. 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. Ensure that it meets all the existing communication software and interface hardware, do not need to modify any software RS-232-based work.
UT-208 optical isolation interface converter for point-to-point and point-to-multipoint communications provide a reliable connection, point-to-multipoint each converter can be allowed to connect 128 RS-422 or RS-485 interface devices, data communication speed 300-115.2KBPS, with a power indicator and data flow indicator to indicate fault conditions, communication support RS-232 to RS-422, RS-232 to RS-485 conversion.
