Networking device measures both voltage and current

Using the signals in which the integrated analogue output sensors provide, the networking device produces data for the users network. A Programmable Gain Amplifier (PGA) is also integrated within the ED-549, allowing full-scale 12-bit readings from signals as small as ±75mV. Each of the 8 channels is individually configurable for voltage or current input with its own programmable gain.

Via user-selectable jumper-enabled resistors, the Ethernet networking device offers enhanced flexibility by allowing both voltage and current measurements. Inputs can be configured independently on each of the eight channels, allowing any mixture of measurement channels. During current measurement, input ranges of ±20mA, 0-20mA or 4-20mA are provided.

Featuring a power input range from +5 to +30V DC, the networking device accommodates the 24VDC factory floor supply and can be powered from any PC or laptop USB port. This dual power supply input allows a redundancy connection, preventing downtime in the event of failure of either power supply. There are three isolation domains: the analogue inputs; the power circuitry and the Ethernet port providing 1500V protection.

Using the device's software interface, users can configure, monitor and control the ED-549 on a Windows computer without any extensive programming or networking knowledge. The networking device is also provided with a web-based user interface, allowing the user monitor the factory floor from a smartphone or tablet. Compatibility with legacy software via a Windows COM port and industry-standard applications such as LabView, MATLAB and Agilent VEE are also offered.

The Ethernet networking device features a 22.6mm-wide footprint, removable colour-coded and numbered terminal blocks and a –30 to +80°C operating temperature range. A calibration certificate, where each voltage range has been individually factory calibrated by precision equipment, is also provided with the ED-549.

The networking device is suitable for use in in industrial process control environments such as water utilities, petrochemical, transportation and food and drink manufacturing, which require the constant remote monitoring of analogue signals.

“Ideal for many different industrial applications that operate in harsh environments, the new Brainboxes ED-549 is a highly flexible, easy-to-use and configure industrial Ethernet device that delivers high-precision remote monitoring of independent voltage and current inputs,” said Eamonn Walsh, Managing Director, Brainboxes. “If you want to get industrial data live into your networked applications this is the product for you.”
