Application and Technology Industrial Feature Set Industrial M Series multifunction DAQ devices offer a set of high-reliability features designed to automate even the most demanding applications. Isolation prevents ground loops, rejects high common-mode voltages, and protects users and equipment from high-voltage transients ±20 mA current inputs provide direct connectivity for 4 to 20 mA process current loops. Programmable digital debounce filters eliminate glitches/spikes and remove noise Change detection triggers on a digital event with minimal processor usage Sourcing or sinking digital I/O...

Long cable lengths and the presence of electrical noise in industrial environments can make accurate voltage measurements difficult. As a result, industrial transducers that sense pressure, flow, proximity, and so on often emit current signals instead of voltage. Each of these current loops contains a power source, a transducer, and one or more data acquisition devices. The current signal is typically between 4 and 20 mA, with 0 mA indicating an open circuit; power supplies are typically in the range of 24 to 30 VDC. Because all the current that flows from one lead of the power supply must return...
