The MI Model 4240A Low Thermal Matrix Scanner is ideal for use in automated stress and thermometer applications where a number of objects need to be calibrated efficiently and accurately. The MI 4240A improves efficiency by eliminating the need to constantly change connections when measuring multiple voltage sources. Model 4240A has 40 two inputs and two outputs.
The relays for the inputs can be activated using both front control and the IEEE488 Interface Bus. The corresponding LED indicates which channel is selected. Combined with model MI 8000A Automatic Potentiometer from MI, model 4240A is a means to realize a fully automatic voltage measuring system.
Ultra sensitive, high efficiency, polarized relay technology is used to eliminate automatic heating in the relay during the production of this low thermal matrix scanner. The relays are the latest technology used in the telephone industry. The relay boards are thermally insulated to maintain the balance in the switching areas. The low thermal terminals are mechanically connected to the copper pads on the relay boards. This to reduce the thermals normally generated by soldered connections, resulting in fewer switching errors. The connection cable can also be ordered with the 4240A voltage matrix scanner. The connection wire is available in two or four wire configurations. The wire can be ordered in lengths with screens already attached. No 18 gauge solid copper, silver plated, shielded Teflon cable is used.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
