For Symphony Plus system applications, ABB SPDSM04 provides the function of a Digital Slave Input Output Module.
For replacement planning, this class of module brings discrete field status into the control system. Typical signal sources include switches, relay contacts, permissives, and equipment-status circuits when they match the module's electrical requirements. The product remains part of the broader control and signal-handling arrangement.
For system maintenance, this product is associated with the Symphony Plus family and the PLC modules category. Configuration and compatibility should be confirmed for the exact system in which it will be used. The original wiring and configuration records should guide application.
ASEA Brown Boveri - ABB Symphony Plus SPDSM04 is a newer remarketed version of the long standing ABB Bailey Infi 90 IMDSM04.
