M-Bus (Meter-Bus) is a communication interface widely used in various meters, such as electricity meters, water meters, heat meters, etc. It is easy to install (two-wire system includes power and communication function) and robustness are the most important features. I-3591 is the M-Bus repeater developed by ICP DAS, its main function is to strengthen the driving ability of M-Bus, extend the communication distance of M-Bus, reshape the signal waveform, etc. Provide the M-Bus master with better communication capabilities. I-3591 does not require any settings, it can be used directly after connecting to the line, and easy to use is also one of the main features of I-3591.
