MIO168 + AFE3

EEZ DIB MIO168 Mixed I/O module with AFE3


Out of stock

SKU: 00063 Categories: , ,

The MIO168 is a versatile module that offers multi-channel generation and measurement of digital and analog signals. In the basic version it offers 8 digital 2-level inputs and 8 low-side high current switches. It additionally offers two bipolar voltage or current analog sources and two unipolar voltage sources and two square wave generators. In combination with AFE3 it can be used for isolated simultaneous measurement of the power of two circuits as well as the efficiency as a ratio of two powers.
