Supply m-bus converters for remote reading

М-bus (Meter-bus) is a new European standard for remote reading of tax instruments and different types of sensors. The reading is accomplished by several different methods - from direct reading of current indication of the instruments to fully remote reading of all devices in the net by GPRS technology. The use of M-bus interface allows fully electronic reading of data with all the benefits of it. М-bus supply converters are the basic device, and all the net is build on it. They have the following functions:

- supplying m-bus net and power supply for slave devices

- provide data channel for data exchange between slaves and main reading device

- serve as a 'bridge' to connect slave devices with main reading device (such as PC, PDA, etc.)

Types of m-bus supplying devices

Generally we offer two types of m-bus masters: for small networks up to 32 slaves, and for big networks up to 250 slaves. Both types have RS-232C interface. Via RS-232C serial interface they interact with the extern device for reading - directly personal computer or through one of our converters (USB, IrDA or GPRS transceiver). We can also offer M-bus repeater for doubling physical dimensions of the network up to 500 slaves. All types of M-bus masters are powered from standard power supply 220/230 VAC, and they can work without problems down to voltage of 170 VAC. Outputs are protected to short circuit and high voltages.

Security

Special precautions are taken to avoid eventual attempts of data manipulating, read by the devices. For that purpose M-bus supply units do not record any data - they are just transceivers (except some service data). The service data is written once by the manufacturer or when installing the device and setting the system.
