DS/TS Data Acquisition System (DAS), Gateways

Data Acquisition System (DAS) is intended for data collecting from DS/TS using PLC (6-10 kV), data transmission to upper level and SCADA integration

Basic features

Extended frequency (16-1 000 kHz) for PLC communication.
Data transport system with error-control decoding.
Data reduction systems.
Batch mode allows tree network operation with roll-call polling all of the DS/TS.
The system is equipped with a line trap and a coupling capacitor specifically designed for ELV lines.
Transmission line (overhead, underground) matching is carried out by the appliance, coupling filter is not required.

Data communication network interfaces

Interface 10/100Base-T; Ethernet (IEC 60870-5-104, AMI )– 4 pcs.
Interface RS232 (IEC 60870-5-101)
Interface RS485 (IEC 60870-5-101, AMI, Modbus)
TS signals
Self-test control and parameter configuring system, monitoring of user traffic flow within network elements.

3 types of equipment and channel condition signals are displayed on the front panel: normal condition, warning signal and contingency signal with external alarm output.
Structurally Data Acquisition System is a 19” rack not more than 1U high .
Electromagnetic control in compliance with STO 56947007-33.060.40.177-2014 requirements.
