Electronic Single-phase Energy Meter RS485
The RS485 communication scheme is a wired data transmission method, which is applied to occasions where 485 communication lines are convenient to arrange. The RS485 remote prepayment electric meter adopts a cost-effective networking of RS485 electric meters + collectors, realizing functions such as remote meter reading, remote control, and remote recharge of electric meters. Compared with the traditional IC card electricity payment mode, the RS485 remote prepayment is a further upgrade, which is time-saving, labor-saving and efficient. To a large extent, it saves the initial networking cost and reduces the later operation and maintenance cost.
