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
+5VREF (Imax: 60 mA) present at terminal J24.

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 dierent outputs). Groups from 2 to 5 outputs have 2
“common”polesforeasyassembly.
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).
Makeup of the groups version relays with same insulation

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