The SMART2000 Telemetry System is a Hi-Tec acquisition, logging, and control system based on ARM microprocessor. Due to its design architecture, it can serve all the environmental applications including meteorology, hydrology, and water and air quality. The Felix Technology RTU has 8 isolated differential analog inputs, enabling data acquisition with a high resolution up to 16 bits. It features 6 digital inputs/outputs, all protected allowing the user to control various sensors and auxiliary equipment.

Four digital interfaces, RS232, RS485, USB, and Ethernet are built-in, featuring communication via ASCII, PROFIBUS or MODBUS.Data storage is achieved by an internal flash and an SD memory card, optionally. A rotary switch and 4-line LCD on the front panel allow the user to enter or modify a number of different modes and functions, such as sampling rate and averaging time, as well as offset and gain.
The power supply can be backed-up by a rechargeable battery. A built-in charger ensures that the battery is fully charged. A power down mode with wake-up on the timer on external input allows an extensive operation on the battery power. Appropriate circuitry is implemented for using a solar panel for operation where main power is not available.

Configuring of the data logger can be performed using software working under WINDOWS 98 / ME / NT / 2000 / XP/7 operating systems.

Measurement of temperature can be performed using a thermistor Pt100 connected to one of the analog inputs. Wind speed and direction, humidity, precipitation and other environmental sensors with current or voltage output can be logged through analog inputs. SMART2000 supports measuring methods with 2, 3 and 4 wires. The digital signal inputs can be used, for the sensors with frequency or counter outputs. Special calculations of measured values are possible using arithmetic channels.

The data logging software logs analog and digital inputs periodically or based on input events, and stores data in the internal Flash, or on a Micro SD card. The telemetry system has a web interface for configuration and data retrieval, accessible through a direct USB connection to a PC, through GPRS, or through the internet. Optional modes of remote communication are PSTN, GSM/GPRS, RF, and satellite.
