FD systems are a series of fast (470 Hz / channel) and flexible data acquisition modules to be used in the field and on test benches. 3 different models are available with 5, 10 or 15 universal synchronized inputs (1 ADC per channel).All necessary configuration and management software (WEB server technology) are embedded into the plug-and-play system and allow remote control of the acquisition through any web browser: Setup, start, result display, monitoring and data exportation. FD memory capacity (internal and external via USB drive or SD card), allows several months of data to be recorded.FD modules perform measurement, monitoring and recording of analogue and digital signals coming from sensors of physical or electrical values. These signals can be:Voltage: Standard 0-100 VCurrent: 0-20 and 4-20 mA with external shuntsThermocouples: Type K/T/J/N/E/R/S/B… with or without cold junction compensationResistance: 0-3000 ? and 0-200 k?RTD: Temperature sensors (Pt100 / 500 / 1000…) in 2, 3 or 4 wiresFrequency: up to 10 kHz measuring frequency and countingFast and still accurate, FD 5 / 10 / 15 modules perform acquisition from every input simultaneously up to 470 samples / s / channel. 3 scanning speeds are avalaible, matching 3 different levels of accuracy. Measurement can be performed with different frequencies, resolutions, trigger conditions and types of inputs, making FDs perfect for measurement and control of fast phenomenon.Channels being synchronized, the scanning speed does not depend on the number of channels scanned and recorded. The instruments are freed from multiplexer constraints: regardless of the number of channels acquired, the speed will remain optimum. Two additional slave modules can be connected to the main module to extend the number of inputs available and make a network.Accurate monitoring and flexibility are ensured with:Up to four limits per channelUnlimited number of calculation channels2 analogue 0-10 V outputs2 output relays5 TTL inputs/outputs1 24 VDC output (to supply up to five 4-20 mA sensors)Ethernet TCP/IP, USB, WIFI external access point in option
