chapter product introduction
1、 Product overview
2PORT RS485is a type of industrial automation system communication, solveRS-485bus star structure networking, andRongRS485standard, able to extendRS485the communication distance and transmission rate of the bus network reach115.2kbps, increaseRS485the number of network devices. Built-in photoelectric isolator, able to lift up1500Visolation voltage,Abinterface with fast transient voltage suppressionTvsthe protector can absorb the impact of high energy and large current and protect the circuit components behind. This protector can effectively suppress lightning and lift each line600Wlightning Surge Protection power, as well as surge voltage and transient voltage generated on the line for various reasons.RS485The judgment Circuit adopted in the working mode of can automatically sense the direction of data flow, and can automatically switch the control circuit, which can be easily solvedRS485send and receive conversion delay problem.RS485Interface transmission distance greater3000m, can directly adapt to all kinds of upper computer configuration software,PLC,DCS, power data collection and monitoring, etc. Modular power supply,RS485communication electrical signals are isolated from each other, effectively inhibiting all kinds of serial mode and common mode interference, and ensuring the stable and reliable operation of the module at the same time.
