6.6.1 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o󰀨;onMAN1itisalwaysswitchedon;onAUTOtheswitchstate
isdenedbytheapplicationprogram.Thisisnotanemergencymodulethatwill
work even when the Saia PCD
®
isswitchedo󰀨(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).
