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 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 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)
