Distribution Terminal Unit (DTU)
Model:
DTU
Overview:
The distribution automation terminal adopts advanced digital signal processing technology, high-speed industrial network communication technology, multi-CPU integration technology, an embedded industrial chipset, and a multi-task real-time operating system. It has strong stability, high reliability, good real-time performance, wide environmental compatibility, and powerful functions. It is suitable for detection and control needs in switchgear and ring main unit occasions in the distribution system. It is a new generation of microcomputer-based distribution automation remote terminal devices that integrates telemetry, telesignaling, remote control, protection, and communication functions.

· Powerful Platform & Modular Design: Utilizes a standard 4U chassis with a popular modular, front-pluggable structure. This design ensures high circuit commonality, excellent interchangeability, easy maintenance, and simple technical upgrades. A single main control board integrates both the "algorithm" and "communication" functions, yielding a simple and highly reliable system architecture;

· Superior EMC and Reliability: Employs multi-level isolation and robust shielding, granting the unit excellent electromagnetic compatibility (EMC) performance and high field operational reliability. The device requires no external anti-interference measures when panel-mounted, simplifying design and maintenance;

· High-Density SCADA Resources: Within a compact 4U, 19-inch core unit, the device supports 16 feeders, with each feeder providing 3 Telemetry (Remote Measurement), 7 Tele signaling (Remote Status), and 2 Telecontrol (Remote Control) channels;

· Flexible, Code-Free Configuration: The maintenance tool software offers three configuration functions channel setup, setting parameter definition, and forwarding point table configuration allowing changes without program modification, greatly enhancing device reliability;

· Optimized Maintainability: The device maintenance tool software is logically segmented into four parts (General, Engineering, Production, and Development), providing comprehensive maintenance features tailored to the roles of different personnel;

· Advanced Fault Recording (Oscillography): Supports circular storage of over 64 fault records. Recordings capture 4 pre-fault and 8 post-fault cycles at a sampling rate of 128 points/cycle, capable of simultaneously recording data for 2 circuits. Accuracy meets State Grid (SGCC) specifications.

· High-Resolution HMI: Features a user-friendly, high-resolution 160x160 graphical display with a rich content display.
