Videographic recorder with integrated data-logger
However when a USB flash drive is plugged permanently, it can significantly extend the recording time without a need of data transfering from SRD-99 to a PC. For example: 1GB flash drive allows continuous data recording for over 1 year (8 channels recorded every 1 sec., approx 250 millions data recordings)! Individual alphanumeric description (text) of each of the recorded channels is possible.
The multilanguage menu assisted with full text descriptions makes the unit configuration process quite easy. However, due to a significant number of configured parameters it is advised to use the attached configuration software for PCs. New in SRD-99 are 2 outputs - electronic relays with max. load 24V AC (35V DC) 200 mA. Main function of outputs is
a signalisation of critical situations, but thanks to expanded menu it is possible to use it in numerous control and regulation applications. Both outputs can be driven by single measurement channel or by group of channels (from 1 to 8 channels) with individually adjustable thresholds for every measurement channel. Signalisation of output state is made as two fields described R1 and R2 in left upper corner of LCD screen.
