About the SB 1223, DI 4x 24 V DC/DQ 4x 24 V DC 100 kHz
The Siemens 6ES7223-7BF50-0XB0 is a SIMATIC S7-1200 G2 signal board (SB 1223) that adds 4 digital inputs and 4 digital outputs, both rated 24 V DC and switchable up to 100 kHz for high-speed counting and pulse output. It plugs directly into the CPU housing without consuming rack space and switches loads up to 0.1 A per output.

- UL
- cULus
- RCM
- KC
Selection Notes
The 100 kHz switching speed on both inputs and outputs handles quadrature encoder feedback and PTO pulse trains that a standard low-speed signal board cannot; pick a conventional-speed SB instead when the application only switches proximity sensors and relays and doesn't need high-speed counting. Because S7-1211C/1212C CPUs have a single signal-board slot, this combined 4DI/4DO board covers a mixed input-and-output need in one slot rather than requiring a DI-only and DQ-only board.
Applications
Adding compact high-speed digital I/O to a small SIMATIC S7-1200 CPU without expanding the rack: quadrature encoder or limit-switch inputs, PTO pulse outputs for simple positioning, and general 24 V DC switching where board space is limited.
