DO3(phase)
DO3N(neutral) Under voltage output 230Vac, 50Hz, 2A (AC1).
(*) For the sizes of 0466, 0475 and 0485
Wherever the GI optional plant management kit is present, you have a third controller located inside the electrical board acting as
an expansion module of the I/O ports. By mean of this controller, it is therefore possible to increase the number of logic functions
that can be managed by the main controller; in particular, the following I/O ports can be activated by the previous controller.
