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 +5V

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).
