Active isolation industrial grade RS485 repeater 485 amplifier distance extension | Обустройство дома

1.485 relay isolator (without power) 2.485 relay isolator + (DC12V power)     Communication parameters: Conformance: EIA RS-485 standard RS-485 signals: A+, B- RS-485 signals: A+, B- Mode of operation: asynchronous transmission, point to point, point to multipoint, two wire and half duplex. Transmission medium: ordinary, twisted pair or shielded wire, with shielded twisted pair or dedicated communication wire is recommended Baud rate: 300 ~ 115200bps, automatic detection of serial port baud rate Direction control: automatic direction identification and automatic control of data transmission direction. Transmission distance: 1500 meters Communication protocol: transparent transmission Interface protection: 1500W surge protection, 15KV static protection, 2500V communication isolation, and lightning protection. Working environment: 0 ~ 60 C, relative humidity 5% ~ 95% Concatenation: the RS485 terminal can be cascaded with 256 enhanced RS485 devices at most. (The number of devices that can be cascaded in practice depends on the type of 485 chip used by other devices. At present, the common 485 chip can be cascaded to 32 communication nodes, and the enhanced 485 chip can be cascaded to 256 communication nodes at most. Of course, the number of nodes that can be achieved in practical application is also related to the communication environment, wire, communication distance, and communication rate. Working power supply: Input power: DC9 ~ 24V wide range DC voltage input Power consumption: when DC12V is input, the current is about 30mA Appearance size: Length * width * height: 82 x 50 x 32mm Shell: high quality plastic shell with high safety factor of insulation.
