RS-485 Repeater, Industrial Grade Amplifier Isolated Converter for Attendance Machine, IC Card Charging System

Description: This isolated RS485E repeater is a kind of high-performance industrial grade RS485 amplifier and extender. It can automatically sense data flow direction and communication baud rate, not requiring any control or handshaking , and ensure transparent data transmission. Equipment power supply and communication are completely isolated, with and static . It features long distance transmission, high speed, stable and reliable performance. Widely used for attendance machine, IC card charging system, automation control, access control system, parking lot, dining service system, highway toll system. Specifications: Recommended Value (Typical) Limit Value Working Voltage 9V~36V DC 9V~36V DC Rated Power 0.36W (9V/35mA; 12V/27mA; 24V/15mA) 0.5W Working Temperature -30~70 -40~80 Responsible for Capacity 1~128 node 128 node Communication Distance 0~1200 meters 1200 meters Communication Rate 300~500K bps500Kbps Note: It is suggested to use RS485E equipment under recommended value for long-term stable operation. Equipment will not damage when working under limit value, but may result in performance degradation. Do not exceed the limit value, otherwise it may damage the equipment. RS-485 bus wire should be 2-core shielded twisted pair copper wire, of diameter 0.5 to 0.75 square millimeters, impedance 38 to 88 ohms / km, capacity of 30 to 50 nanofarad / km, pitch is 20mm (if wire distance is not more than 500 meters, the standard can be appropriately lower, but must be twisted pair) Package Includes: 1 x RS-485 Repeater
