The SRD-99 was the first device launched in the MultiLog line of DIN panel-mount logging systems and now it is updated as the SRD-99X.

It’s a super-capable logging device yet affordable. The SRD-99X’s display is a clear and versatile 2.9″ monochrome graphic LCD and settings can be changed and interrogated using the integrated touch keys or via USB or RS485 (dependent on version).

It can integrate up to eight universal inputs: temperature (RTD + TC) or analogue (U + I), one digital input for controlling a recording process, 2 electronic relay outputs with max. load 24V AC (35V DC) 200 mA, USB PC port for direct (by cable) PC connection to share data and USB Host port (front or rear) for flash data storage and configuration transfer.

Outputs are generally connected to signal critical situations with relays driving alarm buzzers or lamps.  However within the expansive menu options (as standard) are features allowing the SRD-99 to handle numerous control and regulation applications.

The new MultiLog SRD-99X can record and display current values as well as presenting logged parameters in the form of bar graphs and pie charts.
