A series of galvanic isolators consisting of several independent and self-contained cells designed for processing 0–4–20 mA current loops. Each input can be active or passive, allowing for the measurement
of current from an active transmitter or for powering a two-wire converter and measuring the loop current.
Thanks to the modular design of these isolators, it is possible to isolate up to 4 independent loops or
to obtain, by connecting the inputs in series, up to 4 isolated copies of the same loop.
Similarly, connecting the outputs in series or parallel allows for higher loads or
higher output currents.
