Simex MultiLog SRD-N16 Series Paperless Recorder is designed to record and display current values and present technological parameters in the form of charts. This device can be equipped with up to eight temperature (RTD/TC), current, or voltage inputs, one digital input for controlling the recording process, and a USB Host port for flash data storage. Due to the extensive number of configurable parameters, it is recommended to use the accompanying PC configuration software.

Simex MultiLog SRD-N16 Series Paperless Recorder features two relays with a maximum load of 1A/250V AC. These outputs are primarily used for signaling critical situations, but the expanded menu allows for use in various control and regulation applications. Each output can be driven by a single measurement channel or a group of channels (from 1 to 8), with individually adjustable thresholds for each channel. The output state is indicated by two fields labeled R1 and R2 in the upper left corner of the LCD screen.
