WARNING: the 21 Vdc available at the +Vdc terminal (J2) can be used to power any active probes, the maximum
current is 150 mA, thermally protected against short-circuits. To supply the ratiometric 0 to 5 V probes, use the

For the requirements refer to Figs. 3 to 5 (reference NO*, NC* and C*). Note the presence of outputs with changeover
contacts kept separately (that is, without the poles shared between different outputs). Groups from 2 to 5 outputs have 2
“common” poles for easy assembly.
Make sure that the current running through the common terminals does not exceed the rated current of each individual terminal,
that is 8A.
Insulation distance the outputs can be divided into groups. There is double insulation between groups (between cells in
the table).
Note: the relays in the same group must have the same power supply (24 or 230 Vac).

Note: the relays in the individual cells of the table have basic insulation between them, while
between groups (cell-cell) there is double insulation.
