The DICO1 and PICO1 are 1-phase true RMS AC/DC monitoring relays for over+under, over+over or under+under current and voltage, with the measuring range selected by DIP-switches. DICO1 can also perform DC plus/minus measurement by short-circuiting pins Z3 and Y1, and the devices can be connected to MI or MP and A82 or E82 current transformers.
Both models have two individual set levels with their own time delay and an output of 1 or 2 x 8 A SPDT relays, N.D. or N.E. selectable. Level, hysteresis (0 to 30% on set value) and delay (0.1 to 30 s) are set on relative and absolute scales; the document also covers latching and inhibit functions, function/range/level and time delay settings, wiring diagrams, and input, output, supply and general specifications.

They support TRMS AC/DC over+under, over+over or under+under current and voltage monitoring, selectable by DIP-switch.
Yes. DICO1 can perform DC plus/minus measurement by short-circuiting pins Z3 and Y1.
The measuring range is selected with DIP-switches.
The delay functions are separately adjustable from 0.1 to 30 s.
