Analog input cards

We offer several product lines in the range of analog inputs:

1. EP series - measuring cards for three-phase voltage and current measurement, alternatively with a fourth input for direct I0 measurement, for U0 measurement or additional voltage measurements. In addition to phase measurements, the cards also calculate phase to phase voltages, P, Q, S, f, cos φ, THD. If I0 and U0 are not measured directly, the card can calculate them from three-phase measurements. The cards indicate faults on electrical voltage lines according to ANSI standards and can work as protection relays in cooperation with digital I/O cards. Depending on the type of application, the overload capability of the inputs can also be selected, so that data during the fault on the line are available.

2. AI series - measuring cards for industrial standards measuring, usually 20 mA or 10 V,
                   - special fast measuring cards (up to 40 MS/s),
                   - temperature measurement.

3. EQ series - cards for measuring the power quality and energy (they were originally part of the AI series).
