For CPU models with relay outputs, you must install a digital signal (SB) to use the pulse outputs.
2
Up to 200 kHz are available with the SB 1221 DI x 24 VDC 200 kHz and SB 1221 DI 4 x 5 VDC 200 kHz.

The different CPU models provide a diversity of features and capabilities that help you create
effective solutions for your varied applications. For detailed information about a specific
CPU, see the technical specifications (Page 361).
