- Description
The Siemens SIMATIC S7-1200 Signal Board SB1223 6ES7223-0BD30-0XB0 adds 2 digital inputs and 2 digital outputs to an S7-1200 CPU without using a base rack slot, since it plugs directly into the front of the CPU housing. The 24 V DC inputs are current-sinking and the MOSFET outputs switch up to 0.5 A resistive load, giving a compact option for a few extra I/O points.

Selection Notes
With only 2 DI and 2 DO at 0.5 A per output, this board suits a handful of extra points on a project already short 1-4 I/O channels; if the shortfall is larger, an SM 1223 signal module in the base rack is the better fit since it scales to 16 or more channels. Because it occupies the CPU's own signal-board slot rather than a rack position, it does not reduce the number of signal modules or communication modules the CPU can otherwise carry.
