USB DAQ With Storage

[GSAS - Karthick]

Hi, Can i please know if the DAQ with USB interface that could log the Voltage & current has an inbuilt storage. If So, please suggest a module

Hello @GSAS - Karthick.

The MCC LGR-5329 has a USB interface and supports up to 32 GB via a SD card.  This device will log voltage data.  However, a 250 Ohm resistor would be required for each current signal to convert over to a voltage signal.

Since this is a legacy device, it is not recommended for new applications. Please consider the WebDAQ 904 instead.  The WebDAQ 904 supports voltage and current signals, along with other signal types, and also supports a SD memory card.  This device uses an Ethernet cable instead of a USB cable.

Please provide additional details regarding your application's requirements, i.e. sampling rates, number of channels, A/D converter resolution, operating system, preferred software applications or programming languages.

Hi Fausto,

 

We need a minimum of 5 channels, with options for storage, and should measure current from 5-20 mA.

it should have a USB Connectivity.

Hello.

If the data acquisition device is to be connected to a Windows host system at all times via a USB cable, then you can use the host system for data storage.  This configuration widens your options, i.e. USB-1608G Series, USB-1808X. You would still need to use a 250 Ohm resistor for each input channel to read a voltage.  Afterwards, a software application or code can convert the data back to current.  

If you need a standalone, then it is the MCC LGR-5329.
