Controllers AT-8000
AT-8000 Series presents measurement modules and controllers, developed on basis of 32-bit
ARM9 and AVR32 RISC-processor architectures, terminal modules, and communication modules
(interface converters, RF modems, signal standardization modules, IS barriers etc.).
Terminal modules are used for input/output and visualization of operational information by
means of alpha-numeric or colored panels.
Communication modules offer data exchange in remote control and management systems:
− USB B to RS-485 signal conversion;
− USB B to RS-232 signal conversion;
− RS-232 to RS-485 signal conversion;
− RS-485 and RS-232 signal adapting;
− data transceiving between controller and portable transmitter;
− analog signal standardization (amplification, filtering) and bad signal preparing for further
treatment;
− Spark-safe circuit protection from voltage jump (up to 250V);
AT-8000 Series modules and controllers can be applied in oil and gas industry facilities and in
other industries for development of automatically controlled measuring and operating systems
with various configurations.
AT-8000 controllers use the following communications protocols: Modbus RTU Master,
Modbus RTU Slave, Modbus TCP. Operating system type: FreeRTOS, QNX 6.4 (with drivers).
Operating temperature: from -40 °C to +60 °C. Consuming power: 1-30 W. All the constructs
involve clamps for DIN rail.

Innovations in Technological, Metering and Environmental Solutions
AT-8000-base automatic control systems have block-modular construction, depending on
applications. Modules are related by ModBUS protocol through physical channel RS-485, RS-232
or Ethernet. Data transfer to top-level is possible through any wire interface and wireless link by
means of RF modem.
There are also involved Input/output by FLASH-memory (SD, CF, and USB), data backup and
archiving. Visualization of technology process is provided by graphical panels: monochromatic
alpha-numeric panel and colored Touch screen.
