Programmable Dry Contact Ports J23 ~ J25
The dry contact ports J23 ~ J25 are shown in Figure 3-10 and described in Table 3-6 and Table 3-7. The
dry contact voltages are 24Vdc/250Vac, and the current is 5A. 1, 3, 5 is a group of dry contacts, and 2, 4, 6
are another group of dry contatcs. These six-goup of dry contacts are programmable via the Paramset,
and you can select any one from the output signals 1~9 in Table 3-6.
