Type I Data Concentrator Unit
DJTD23-HX3200
Dedicated to automated data acquisition and smart meter reading in low-voltage power systems.
Product Description
The DJTD23-HX3200 series data concentrator, hereinafter referred to as the Type I Concentrator, is a new-generation centralized meter reading terminal product characterized by advanced technology, stable performance, reliable operation, and easy maintenance, developed based on a 1GHz frequency, quad-core high-performance core board, and a unified operating system software platform, while integrating GPRS/4G/5G/Ethernet remote communication technologies, PLC/RF/dual-mode heterogeneous local communication technologies, and high-precision energy metering technology under modular and object-oriented design philosophies. It is suitable for various levels of power utilities, public institutions, public buildings, residential communities, commercial complexes, and trading markets where multi-meter centralized collection of power consumption data is required but data density demands are relatively low. This product complies with the 2022 technical specifications of the State Grid Corporation of China (SGCC) and the DL/T 698.45 standard—Electricity Information Acquisition and Management System—Part 4-5: Object-Oriented Interoperability Data Exchange Protocol.
