Product description

  DJGZ22-SH604 type state grid concentrator is the key equipment in low voltage concentration of power line carrier meter reading system. It can read and save the electricity data of intelligent meters, state grid concentrator or acquisition module and different communication terminal automatically through downward communication channel; also it can exchange the data with the primary station or handheld device through the upward communication. While the upward channel adopts public communication network, supporting the client-side and server two kinds of communication mode, also using the module design, it can change the communication style by changing the communication module.
