LSD-MBUS-03A_V3.0
Overview
LSD-MBUS-03A_V3.0 M-BUS Automatic Meter Reading System adopt TI's design which is based on the European Instrument Bus standard and has been used for many years in developed countries.M-BUS meter reading plays a very important role in AMR application area. It is mainly used for data collection, remote transmission,etc. Its most important feature of the system is:long-distance communication,easy for project wiring,accurate meter reading and low cost.It is very convenient and easy to read kinds of meter (such as water,electricity, gas and heat meter) especially for residential areas and urban high-rise buildings , also other areas which need remote data transmission.
Parameters Data
（1）Display Mode:LED indicator
（2）Operating Temperature Range:0°C～50°C
（3）Work Voltage:220V AC
（4）Master PC Interface:Standard RS232 Interface
（5）Total Current:≤120mA
（6）Current For Repeater:≤3mA
（7）Overload Current:200mA±10％
（8）Transmission Distance:≤ 1Km (it will be changed by numberof nodes and cable impedance)
（9）Communication Baud Rate:300/4800bps
（10）Number Of Nodes:64UL (The change of transmission distance and cable impedance will effect the number of nodes)
（11）Bus Voltage:31V+/- 1.5V(Idle) (Bus voltage will decrease with the increase of number of nodes, cable impedance and transmission distance. When the total current add 10mA, the BUS voltage will decrease 0.24V, users must ensure the voltage of farthest slave is more than 21V.)
The Main Function
Users can use this M-BUS system as a mater or repeater which depend on the practical necessity. This system can't work without a slave which has ability of processing M-BUS data. A slave can be any device which has M-BUS interface.
1.Master Function: to provide bus circuit and transport collected data to PC.
2.Repeater Function: transmit and receive data from previous master or next slave
3.Communication with PC: communication with PC through RS232 interface, users can manage all slaves through PC software.
4.Remote Power supply: slave can use the power supplied by previous master to work without other external power supply.
5.Over-current Protection: When the current flow is too big, which caused by too many slaves or short-current or wires damaged, the M-BUS system will activate the protection function,it cut off the BUS power automatically, and when the error removed, M-BUS system can get the power again by pressing the reset button for a few seconds.
