DI 16x230VAC BA — 16-channel AC digital input module, Basic class, 4-channel groups, input delay 20ms, input type 1 (IEC 61131). [VERIFIED via Siemens official datasheet]

Technical Specifications

Module Type Digital Input, Basic (BA) class
Channels 16, in groups of 4
Input Voltage 230V AC
Input Delay 20 ms
Input Type Type 1 (IEC 61131)

Typical Applications

Used to directly sense 230V AC field signals (such as AC-powered limit switches or pilot devices) without an external signal converter, where DC-only input modules would not be compatible. The 20ms input delay reflects the AC signal filtering needed for mains-frequency inputs.
