1. In order to prevent the harm caused by lightning strike, power line interference and ground potential rise, the power communication and automation system uses an isolation transformer on the terminal, which can prevent the communication and telecontrol equipment from being damaged by lightning strike or ground potential counterattack.

2. Applied to remote meter reading. The remote automatic meter reading function is implemented in the central control room in real time through the network, which can form a regional meter reading network centered on the central control room. Due to the high network transmission rate, about one meter per second, meter reading and billing can be carried out in different periods, the meter reading can be recognized through the electronic eye, and the electronic reading shall be strictly consistent with the meter reading.

3. It supports Poe power supply function, is an adaptive product, and supports multiple interface signal transmission.
