Remote Terminal Units

SYNC 2100 series of Remote Terminal Units (RTUs) are ideal for low voltage and medium voltage electrical networks for Utility Distribution and Medium Voltage Transmission Networks as well as industrial electrical networks.


Overview

SYNC 2100 series are compact RTUs with high performance attributes combining input/output capability, advanced logic programming support and wide range of communication protocols. SYNC 2100, with its modular design, enhanced security, EMI/EMC as well as environmental ruggedness, is suited for a wide range of applications like distribution network assets (RMUs, reclosers, sectionalizers, Distribution transformers, etc.), monitoring/control, substation assets monitoring/control and wind / solar remote monitoring.

SYNC 2100 devices are ideal for various Transmission and Distribution assets monitoring/control, distribution automation and substation monitoring applications. The stand-out features of these products include:

  • Modularity: The RTU is modular and can be customized for exact I/O monitoring requirements using DI / DO / AI modules for physical inputs/outputs.
  • Protocol and Engineering Support: The RTU supports a wide range of communication protocols including IEC 61850, DNP3.0, IEC 60870-101/104 and Modbus, as well as wireless communication interface options (GPRS/CDMA/3G/RF/Zigbee). IEC 61131-3 based logic programming helps in building advanced applications. Support for up to 2 Ethernet ports and 4 serial ports enables direct connection to meters, IEDs and other monitoring devices. This means that a single unit can perform multiple functions reducing the need for additional hardware, thus reducing capital costs.
  • Low Maintenance Cost: A single device also means minimal maintenance, replacement, and inventory costs.
  • Rugged: SYNC 2100 are rugged enough for substation use and comply with IEC 61850-3.
  • Time Synchronisation : The RTU provide improved latency support through time synchronization and millisecond time stamping resolution. This is important in Distribution Automation applications where millisecond differences could be critical in fault diagnosis and problem resolution.
