Ethernet Data Acquisition (DAQ) or Supervisory Control and Data Acquisition (SCADA) Options

LabJack produces low cost, high quality, Ethernet multifunction data acquisition (DAQ) and control products with up to 84 analog inputs, 20+ digital inputs, and 2+ analog outputs when combined with various expansion modules. Below is a list of our devices with the ability to communicate with a PC using an Ethernet connection. LabJack also offers DAQ devices that operate only using USB, and our latest product the T7 has a Pro version that operates using USB, Ethernet, and 802.11b/g WiFi. To view our USB DAQ product offerings please see our USB DAQ (data acquisition) products. To view our WiFi DAQ product offerings please see our WiFi DAQ (data acquisition) products.

Please note that the term "DAQ (data acquisition)" implies products that connect to a PC to acquire data. Hence, the term "Ethernet DAQ" means that this communication occurs using a PC's active network connection. If you need an instrument that can operate independently from a computer we have Data Logging compatable DAQ devices that are capable of periodically recording to internal memory for later use.
