Lightning protection UT 2216 RS232 to RS485 Active converter 1.2KM

 UT-2216 interface converter, compatible with RS-232C, RS-485 standard, can convert the RS-232 signal single end balanced differential RS-485 signal, transient voltage built rapidly inhibit protector, the protector is designed to protect the RS-485 interface, using today's advanced TVS (TRANSIENTVOLTAGE SUPPRESSOR) transient voltage suppressors, under normal circumstances, TVS pipe is the high impedance state, when the two ends of the TVS tube high energy shock withstand instantaneous, it can with extremely high speed impedance and the two ends of the lower, the absorption of a large current, thus the voltage clamp system at both ends in a predetermined value, protection circuit element back from being damaged due to transient pressure impact. The protector can effectively suppress the lightning (LIGHTNING), provides the lightning surge protection power of each line of 600W, and for various reasons produced on the line surge voltage and transient overvoltage, and minimal inter electrode capacitance to ensure high-speed transmission RS-485 interface. RS-232 interface end through a DB9 female connector and is compatible with the RS-232C standard interface to connect, connector RS-485 end of the DB9 male connection. Inside the converter with zero delay automatic transceiver conversion, automatic control and data flow direction of I/O circuit is unique, without any handshake signals (such as RTS, DTR etc.), without jumper setting for half duplex (RS-485) mode switch, plug and play. Ensure that for all existing communication software and hardware interface, without the need for previous RS-232 mode based on any modification of the software.
