Measure and control over Ethernet

-November 28, 2017

DGH has introduced a line of data-acquisition modules with seven input channels for use in monitoring or process control. The D7000 series communicate over Ethernet to a host computer using the Modbus TCP/IP protocol. Because these modules communicate over a network, you can design distributed systems for monitoring phenomena such as temperature, pressure, flow, and just about anything else that uses a sensor. By adding analog and/or digital output modules, you can creates a control system.

Several models in the D7000 series include the models for analog inputs (16 bit), analog outputs (12 bit), and digital I/O.

  • D7100: Voltage (±25 mV, ±50 mV, ±100 mV, ± 1V, ±5 V, ±10 V) inputs.
  • D7200: Current (±20 mA).
  • D7300: Temperature (J, K, T, E, R, S, B, and C thermocouples)
  • D7400: A universal input module that's programmable to accept voltage, current or thermocouple inputs.
  • D7500: Two analog outputs (voltage or current)
  • D7710: 15 digital inputs
  • D7720: 15 open-collector digital outputs
  • D7730: 7 digital inputs, 8 digital outputs

Software support includes LabVIEW, DasyLab, WinWedge, and an API, among others. DGH also offers a free configuration utility.

Competing with companies such as Dataq and Measurement Computing, DGH has several lines of data-acquisition modules that use Ethernet or USB for communications. The company also produces data converters such as RS-232 to RS-485 and USB to RS-485.
