MultiLog SRD-99S and SRD-N16 Multichannel Data Recorders

Brand: SIMEX sp. z o.o.

The MultiLog line instruments have been designed to display and record current values, as well as to present technological parameters in a graphical form.

The devices are equipped with up to 8 measuring inputs.

The panel mounted version, SRD-99, operates universal temperature or analogue inputs, which enables connecting different types of sensors to one device, while the wall mounted version, SRD-N16, operates fixed inputs.

A USB flash drive enables a significant simplification of the unit application: it is no longer necessary to connect a PC and data logger via the RS-485 interface, data downloading can be completed 10 times sooner than in case of using the RS-485 port.

The MultiLog is equipped with 2 relay outputs.

The main function of the outputs is to signal critical situations, but thanks to the expanded menu it is possible to use it in numerous control and regulation applications.

Both outputs can be driven by a single measurement channel or by a group of channels: from 1 to 8 channels, with individually adjustable thresholds for every measurement channel.

Signalizing output states is displayed in two fields, R1 and R2, in the left upper corner of the LCD screen.
