The SRD-99 Multi-channel display is designed to record signal inputs and display current values in graphs and numeric form. The device is equipped with 1, 4 or 8 temperature (Pt100/500/1000) or current (in the 0/4-20 mA standard) inputs, one pulse (digital) input for controlling the recording process, two relay outputs for control and one USB Host port for flash data storage.
The device has the memory capacity of 2 MB (0.5 million data recordings altogether) or 8 MB in version with USB port (2 million data recordings). However when a USB flash drive is plugged permanently, it can significantly extend the recording time without a need of data transferring 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)!The logging rate is programmable from 1 second to 60 minutes.
The internal analogue-digital converter has a 16 bit resolution (12 bit in unit with 0/4-20mA inputs), which provides high recording resolution results. Additionally, individual alphanumeric description (text) of each of the recorded channels is possible. The 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.
