Isolation Converter TENGCON EC7521 Isolator Repeater with 20USD Cheap Price

  Isolation Converter TENGCON EC7521 Isolator Repeater with 20USD Cheap Price   Product Description    Technical data of EC7521    EC7521 is Active photoelectric isolation Repeater of TengControl technology limited .Compatible with the RS- 485 standard,it can electrical isolate the RS485 signals and amplify signals.The built in optoelectronic isolator can be provided isolation voltage 1500 v.The fast transient voltage suppressor (TVS) not only can  effectively restrain the Lightning and ESD,but also can effectively prevent the lightning strike and interference.Due to the RS - 485 support two line half duplex,That is to say, the RS - 485  which have only two line not only need to send data but also need to receive data.Handshake signals (such as RTS, the Request To Send) usually control the direction of the data,The circuit of EC7521 can automatically perceive the direction of data flow ,And automatically switch to be controlled,So It is easy to form a RS - 485 network without any hand signal. ThisRS485 enable control is completely transparent,and does not need do any software modifications based on the previous works for RS - 485.   EC7521 Active photoelectric isolation Repeater can provide reliable connections for point-to-point and point to multipoint communication.it can be allowed to connect 32 RS485 interface equipments for  Point to multipoint. Data communication rate from 0 to 500 KBPS,Yellow LED can indicates data flow from AO BO network to A1 B1 network.   Introduction
