Ruggedized Ethernet extends SCADA/DCS into harsh settings


Solartron Inc. launched the Ethernet version of its isolated measurement pod (IMP), E-IMP. This new remote data acquisition module provides an Ethernet TCP/IP connection to 20 multifunction analog/digital measurement channels in a ruggedized housing, suitable for wide-area monitoring of process and equipment under hostile environmental conditions.

“We developed the IMP concept to eliminate one of the most significant SCADA implementation costs: signal cabling from the sensor to the measurement system,” said Tony Wright, sales manager. “Integrating Ethernet protocols into the IMP allows control engineers to take advantage of existing IT networks and construct high-precision distributed data acquisition systems and economical DCS and SCADA front-ends.”

The IMP concept is simple: control parameters are measured at source by accurate, high-precision data acquisition modules. Ruggedized IP55/NEMA Class 4 enclosures and rigorous electrical isolation allow IMPs to be installed in harsh environments-including areas of high interference and vibration-very close to the point of measurement, eliminating costly cable runs.

Already, the company has some 30,000 IMPs of five different variants installed worldwide in diverse applications including monitoring of nuclear, fossil and combined-cycle power generation plants.

E-IMP extends this proven remote data acquisition concept with built-in TCP/IP protocols, allowing direct connection via RJ-45 connectors to computers or off-the-shelf 10base-T hubs, further reducing the cost of installation.

Solartron`s Windows-based E-IMPView software speeds the set-up of simple Ethernet IMP-based data acquisition systems by eliminating the need to understand complex command structures. E-IMPView interrogates the Ethernet network, collects information on the E-IMPs that are online, and displays the information in the form of a topological map. Further information is available at
