Product Description:
The M-Bus is a bus optimized for the reading of measurement instruments like energy counters, hot and cold water counters, gas, pressure, sensors and actuators, etc. Nowadays, more and more manufacturers implement the M-Bus interface in their counters, making it the ideal basis for remote reading applications. Our M-Bus Master (M-Bus converter) is universal and simple M-Bus Master that can be connected up to 250 M-Bus devices. This device also converts M-Bus signal to RS232 or RS485 so basically you can integrate this device in your remote data acquisition systems with ease.
Product Features:
- RS485 transmission direction: automatic
- Supports Bi-directional communication
- MAX amount of MBus devices: 250 (375mA)
- MBus short connection protection: yes
- Power supplier: 90-250V ~, 50-60Hz
- Mounting type: on DIN rail
Overview:
M-Bus Master / M-Bus Converter 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 / M-Bus Converter.
