Product Description
The M-Bus is a bus optimized for reading of measurement instruments like energy counters, hot and cold water counters, gas, pressure, sensors and actuators, etc. Many of the manufacturers implement the M-Bus interface in their counters, making it ideal basis for remote reading applications. Our M-Bus Master is universal and easy M-Bus Master that can be connected up to 250 M-Bus devices. This device also converts M-Bus signal to RS232 or RS485. Thus, you can integrate this device in your remote data acquisition systems with ease.
Overview
M-Bus Master is dedicated to convert M-Bus signal to RS232/RS485 and vice versa. Up to 250 M-Bus devices can be connected to M-Bus Master.
