The collector is an expansion network device of AMR intelligent meter reading system. Each output port leads out an expansion bus, which connects the meter unit. The collector establishes a channel for the intelligent meter reading network terminal equipment and manages the meter unit, so that the structure of the meter reading network is clear, the work is localized, and the communication efficiency is improved.

Product features
| With lightning protection function and bus isolation function |
| The internal circuit can automatically sense the direction of data flow, automatically switch the enabling control terminal, and amplify and enhance the signal |
| The system accesses the inner table unit of the corresponding collector output channel through addressing, without affecting the work of the inner table unit of other collector output channels |
| Provide power supply and communication channel for meter unit during network data transmission |
| Amplifying the signal of the communication link can extend the network transmission distance and increase the network load capacity |
| It only supplies power to the meter unit at the moment of meter reading, reducing the overall power consumption of the system and having strong anti-interference capability |
