I/O and supply detail
The 1SVR440723R0000: The 12 digital inputs are typically 24 VDC sink/source, configurable through the base-unit programming. The 6 relay outputs are form-A (SPST-NO) contacts rated for general-purpose switching up to the base-unit's specified current. The 100...240 V AC supply powers the module's internal logic and output coils; no separate 24 VDC bus is needed for the expansion itself.
