DATALOG series of data acquisition systems are aiming to measure, condition, process, monitor and record analogue and digital signals from all common types of physical sensors. 3 different models are available with 2 (DATALOG 20), 9 (DATALOG 90) or 14 (DATALOG 140) input / output boards.
The system can be supplied in various configurations with a choice of input and ouput boards as well as options such as built-in display and printer. DATALOG systems perform measurement, monitoring and recording of analogue and digital signals coming from sensors of physical or electrical values. These signals can be:
- DC and AC voltage: 0-100 V
- Current: 0-20 and 4-20 mA with external shunts
- Thermocouples: Type K/T/J/N/E/R/S/B… with or without cold junction compensation
- Resistance: 0-300 kΩ
- RTD: Temperature sensors (Pt100 / 500 / 1000…)
- Strain gauges
- Dry contacts
DATALOG is equipped with RS 232 or RS 485 interface, ASCII protocol and Modbus RTU (for communication by modem or radio, on request). Combined to VISULOG data management software, it makes an advanced real time supervision system.
4 thresholds can be programmed per channel. Every threshold can be associated to a specific relay output and eventually to a conditional handling.
2,000 channels are avaible per module. The channels can be real (input or output), or fictive, in order to make mathematical, bolean and statistical calculations. The calculation channels can be defined over a channel or between channels. 100 linearization tables of 40 pairs of points each are available (measured value associated to calculated value), allowing sensor corrections to be recorded and applied.
