PCD3.A810, Digital manual control module with 4 relays,
2 with changeover, 2 with make contacts
Application
The module has 4 relay outputs: 2 changeover and 2 make contacts. Each chan-
nel 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 inte-
grated contact protection (for emergency and manual operation, see also section
3.20).
