Description
The SRD-99 device is designed to record and display current values as well as to present technological parameters in the form of graphs. The device is equipped with 8 temperature (Pt100/500/1000) or current (in the 0/4-20 mA standard) inputs, one pulse (digital) input for controlling the recording process and one USB Host port for flash data storage.
Internal memory size: 2 MB (0.5 million data recordings altogether) or 8 MB in version with USB port (2 milions data recordings).
External memory: USB flash . When the 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).
