Secondary Electric, Dual A/D, G-Force, and Thermocouple Expanders

Need to measure lots of different Voltages, Currents, Temperatures, A/D channels, G-Force channels, etc.? Our systems make this very easy to do. All you need to do is order Secondary Expanders below. When the secondary expanders are used with our Standard (Primary) expanders, up to 6 Temperatures, 4 Dual A/D Channels, 4 G-Force Channels, 2 Voltages and 2 Currents can be measured simultaneously. And, additional custom Secondary Expanders are available if what you need is not avaiable!

First, please read the short document explaining the fundamentals and limitations of Secondary Expanders, by clicking here.

Then, order the Secondary Expanders you need below. If you have any questions about using Secondary Expanders, don't hesitate to email us at support@eagletreesystems.com!
