low power consumption and high immunity to electromagnetic interference. The bus pins on the bus side of the NSi8308xE is designed with ±10kV ESD protection to ground at system level. This product is designed with a fail-safe circuit that ensures the receiver output is logic high when the ...
A circuit is described that provides fully isolated RS-485 full-duplex data communication with only two integrated circuits (ICs). An internal transformer-coupled isolated supply and internal optocouplers in the data path provide typical isolation to 1600Vrms for 1 minute or 2000Vram for 1 second...
equipment,achieve function of RS-485network connection.The isolation RS485circuits of using a piece of power isolation module,three light couplings and RS485transceivers and device are only need to adopt a RS485isolation module now.Simplify the customers on the isolation requirements of the design.
the circuit is simple, the remarkable characteristic is that the circuit and the logic and strong electricity part of an electric energy meter are isolated strongly, 8kV isolation intensity can be carried out, the switch frequency is high, the working input voltage is low, and only 3VDC is ...
