The SRD-N16 data logger is designed to record signal inputs and display current values in graphs and numeric form. The SRD-N16 is equipped with 1, 4 or 8 input channels, suitable for either temperature (PT100/500/1000 or Thermocouples) or analogue (0/4-20mA or 0-5/10V) inputs across all available channels. A pulse (digital) input for controlling the recording process and 2 relay alarm outputs driven by single or group of channels with individually adjustable thresholds for each channel. A USB Host port is available for flash data storage and configuration transfer. The SRD-N16 will also interface with RS485/Modbus RTU networks.
Features
The device has the memory capacity of 8 MB (3 million data recordings altogether). 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. The logging rate is programmable from 1 second to 60 minutes.
The Loggy Soft program enables the visualization, archiving and printing of measurements (e.g. temperature, humidity, pressure) stored in the MultiLog device memory.
The S-Toolkit software enables configuration reading and writing operations, updating the device firmware and obtaining basic information on the MultiLog series devices through RS-485 serial interface or flash-disk devices plugged into USB port.
