EQUIPMENT
RTU-327LV data acquisition unit
Data acquisition and transmission unit for automated metering systems. E2 - 2 RJ45 Ethernet ports, 10/100/1000BaseT. Power supply: 10-36 VDC.
Current production uses the LV designation only.
Certificates and documentationInterfaces and peripherals
Monitor connections: 2 ports - 1 × HDMI and 1 × DisplayPort (DP).
Interfaces support a monitor, keyboard and mouse for operator interaction. The USB port accepts a HASP key, the hardware carrier of the device-specific licence code.
Typical peripheral standards referenced in the documentation:
- ГОСТ Р МЭК 60950-1-2005 - Safety requirements for information technology equipment.
- ГОСТ 21552-84 - General requirements, acceptance, testing, marking, packaging, transport and storage of computing equipment.
- ГОСТ Р 50948-2001 - Ergonomic requirements and safety of information display devices.
* The built-in serial ports have no surge protection or opto-isolation.
Key benefits of the RTU-327LV data collection and transmission unit
Long service life and proven reliability.
The product’s mean time to failure is 250,000 hours.
Timely data delivery to higher-level systems.
Retrieving previously collected information from a local archive reduces the delays associated with directly polling large numbers of devices, including when retrieving one-minute load profiles.
Comprehensive power network monitoring.
Collection of data on electricity consumption and export, power and network parameters, as well as power quality indicators, including the harmonic content of voltages and currents.*
Autonomous operation and data retention.
If communication with the central server is temporarily lost, the unit continues collecting and storing data locally and transmits it after the connection is restored.
Reduced load and scalability.
Distributed data collection at individual sites reduces the load on the central server and allows the system to expand while maintaining timely access to information.
Controlled data exchange and access control.
The intermediate layer makes it possible to restrict direct access to devices and establish controlled data exchange between the operational network and higher-level systems.
Remote commissioning in a familiar Windows environment.
The unit can be configured, diagnosed and maintained through a remote connection without requiring an AMR specialist to visit the site.
A unified AlphaCENTER software environment.
Familiar tools at the intermediate and supervisory levels simplify system maintenance, reduce configuration time and enable centralized support for distributed sites.
* The available indicators depend on the capabilities of the connected devices and software support for their protocols.
