ZP-503B lightning protection surge type interface converterCompatible with RS-232C, RS-422, RS-485 standard, can convert single-ended RS-232 signal into balanced RS-422 or RS-485 signal, built-in anti-high voltage lightning protection, can provide up to 2500Vrms isolation Voltage, with a fast transient voltage protection protector and discharge tube, this protector is designed to protect the RS-422 / RS-485 interface, using today's advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) transient voltage suppressor and discharge Tube, under normal circumstances TVS tube and discharge tube was high resistance state, when the TVS tube and discharge tube at both ends to withstand the moment of high energy impact
It can be very high speed to reduce the impedance at both ends, absorb a large current, so that the voltage at both ends of the clamp in a predetermined value to protect the back of the circuit components are not damaged by the impact of high voltage. This protector can effectively suppress lightning (LIGHTNING) and ESD, provide 1500W per line lightning surge protection power, and a variety of reasons on the line generated by the surge voltage and transient overvoltage, and minimal inter-pole capacitance guarantee RS-422 / RS-485 interface for high-speed transmission. The RS-232 interface is connected to a RS-232C compliant interface via a DB9 female connector. The RS-422 and RS-485 terminals are connected via RJ-45 and DB9 male connectors. The internal I / O circuit automatically controls the direction of the data stream without any handshaking signals (such as RTS, DTR, etc.), without jumper settings to achieve full-duplex (RS- 422), half duplex (RS-485) mode conversion, plug and play. To ensure that all existing communication software and interface hardware, do not need the previous RS-232-based work to make any software changes.
