Adopting physical layer transparent conversion transmission, the communication signal delay is less than 50 us, the transmission is stable and reliable, and can be adapted to all equipments which conform to the electrical characteristics of MBUS signal.

Take over250LoadRS-485turnM-BUSconcentratorWith imported chips, the temperature range and reliability are better. RS-485 can support multiple devices in parallel (most of the M-BUS conversion modules in the market can not be used in parallel with multiple devices), which is convenient for application development.
