Product Brief:
\
MWE485-YG photoelectric isolation repeater, compatible with RS-422 and RS-485 standards, can extend the communication distance of RS-422/RS-485 bus network, increase the number of RS-422/RS-485 network equipment, built-in photoelectric isolator and DC/DC isolation module, which can provide isolation voltage up to 2500 Vrms, with fast transient voltage suppression at both ends of the interface. This protector is designed to protect the RS-422/RS-485 interface. It adopts the advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) transient voltage suppressor. Under normal circumstances, the TVS tube is in a high resistance state. When the two ends of the TVS tube are subjected to instantaneous high energy shock, it can reduce the impedance of both ends of the TVS tube at a very high speed. Receive a large current, thereby clamping the voltage at both ends of the circuit to a predetermined value, to protect the circuit components behind from being damaged by the transient high voltage shock. This protector can effectively suppress lightning (LIGHTNING) and ESD, provide 600W lightning surge protection power per line, surge voltage and transient overvoltage generated by various reasons on the line, and ensure high-speed transmission of RS-422/RS-485 interface with minimal inter-pole capacitance. RS-422 and RS-485 input terminals are connected through terminal connectors. The output terminals of RS-422 and RS-485 are connected by terminal connectors. The converter has zero-delay automatic transceiver and transceiver conversion. The unique I/O circuit can automatically control the direction of data flow without any handshake signals (such as RTS, DTR) and jumper settings to realize full-duplex (RS-422) and half-duplex (RS-485) mode conversion, plug-and-play.
