M-Bus Display / Logger / Level-Converter
M-Bus Display / Logger / Level-Converter for 60 slaves
Display
- Front-CPU with LCD and 4 navigation-keys shows important M-Bus meter data
- Autosearch of meters with list generation
- Passcode protection
- Additionally usable as level-converter by the RS-232 interface
- Firmware-update by RS-232
Logger
- Same features as M-Bus Display and additional logging and data storage function
- Historical meter data on LCD
- Configuration and export of meter data by RS-232 direct link or modem
Level-Converter
- Baudrates: 300 up to 9600 Baud
- Overcurrent and short-circuit protection on the M-Bus
- Echo cancellation and collision detection with break signalling
- Displays for power, data transmission, max. bus current and overload in the screw-terminal room
The three members of the W60 Master Family are ideally suited for M-Bus installations with up to 60 meters.
The base model is the M-Bus Level Converter, which is standardly equipped with a RS232 and a RS485 interface. For remote read-out a PC with software is needed.
The M-Bus Display additionally allows real stand-alone operation with the integrated LCD and keypad. Therefore meter data can be displayed on-site with few keystrokes.
The third member of the W60 family, the M-Bus Logger, also automatically stores data at selectable times. The data memory can be exported to a PC or a laptop. Alternatively the use of a modem connection is possible.
