Ethernet Data Acquisition: Analog, Digital and Serial I/O through Ethernet for Distributed Control Systems

Intelligent Instrumentation is a pioneer in Ethernet Data Acquisition systems. We were among the first companies to offer input/output systems for data acquisition and process data with Ethernet interface.

Our EDAS (Ethernet Data Acquisition System) products are widely used in applications ranging from data logging to high-speed system monitoring and control.

Today we offer two product lines for Ethernet I/O systems - either or both provide a rugged base for your distributed control system:

EDAS CE system, shown with 2 of possible 12 I/O modules - click pic for more information

The EDAS CE system: modular and flexible like a PLC, but with the  benefits of a truly open-architecture programmable automation controller.

Choose a CPU and any combination of I/O modules - even a quadrature encoder - giving you up to 192 channels of analog, digital, serial and positional data. Programs and data are stored locally, so that it can be used as a stand-alone data acquisition and control system.

Built-in webserver, remote administration, plus many other features make the EDAS CE a universal data acquisition and distributed control system - a programmable automation controller with Ethernet connectivity.

EDAS-1000 series provides analog, digital and serial I/O over any Ethernet connection. Click pic for more information.

The EDAS-1000 series: a wide range of low-cost Ethernet I/O systems for analog, digital and serial signals. Configure an IP-address and you're ready to acquire and output data over the network.

With our Serial-EDAS you can connect equipment like scales, gauges and machines over Ethernet just as if they were connected directly to your PC.

Get all the details about the EDAS-1000 series.

EDAS CE Flowgram

The Industrial Ethernet IO systems can be used for data acquisition,  machine monitoring and process control.

Either as a stand-alone system or controlled from a remote computer, data can be acquired, processed, stored and shared over the network.

No matter whether voltages, 4-20 mA signals, RTDs, thermocouples or quadrature signals from shaft encoders: we have a solution for almost any sensor.

See our application page for examples on how our customers benefit from these systems.
