The Annex, Section A.3 "Relay contacts" contains measurement details and suggested wir- ing for the relay contacts. For safe switching and a long service life, these figures must be observed.6-42PCD3.A8106.6.1PCD3.A810, Digital manual control module with 4 relays, 2 with changeover, 2 with make contactsApplicationThe module has 4 relay outputs: 2 changeover and 2 make contacts. Each channel has a switch with the settings MAN 1, AUTO, MAN 0. On MAN 0, the relay is always switched off; on MAN 1 it is always switched on; on AUTO the switch state is defined by the application program. This is not an emergency module that will work even when the Saia PCD® is switched off (or defective). The external 24 V supply feeds only the relays, and not the logic. For space reasons, there is no integrated contact protection (for emergency and manual operation, see also section 3.20).Technical dataNumber of outputs:4, 2 changeover (O 0, 1) and 2 make contacts (O 2, 3)
