6ES7223-7BF50-0XB0 – SIMATIC S7-1200 G2, SB 1223 – 4x DI / 4x DQ 24 V DC, 100 kHz, Siemens

6ES7223-7BF50-0XB0 is a second-generation SB 1223 signal board for the Siemens SIMATIC S7-1200 G2 with 4x DI / 4x DQ 24 V DC, 100 kHz.

The SB 1223 signal board is mounted directly in the front of the CPU S7-1200 G2 (under the top cover) and therefore takes up no additional space on the DIN rail – compared with SM modules it is suitable for a small addition of signals without increasing the width of the assembly.

Key advantages
Mounted directly in the CPU, needing no additional space on the rail.
Quick replacement without disconnecting other modules.
Each CPU S7-1200 G2 supports one SB/CB/BB slot.
Compatible with all CPUs of the series S7-1200 G2.
Technical specifications
Order number (MPN) 6ES7223-7BF50-0XB0
Manufacturer Siemens
Type SIMATIC S7-1200 G2, SB 1223
Properties 4x DI / 4x DQ 24 V DC, 100 kHz
Supply from the CPU (no external power supply)
Net weight 0.05 kg
Mounting CPU front (SB/CB/BB slot)
Operating temperature −20 to +55°C, non-condensing
Standards and approvals CE, UL, cULus; developed according to IEC 61131
Typical applications

The board is suitable for adding a small number of signals (e.g. one extra analogue channel, a few fast inputs) where a whole SM module would be unnecessarily large and expensive.

Which assembly it belongs to

The SB 1223 board is part of the assembly Siemens SIMATIC S7-1200 G2. Each CPU has only one slot for SB/CB/BB – if you are already using it with another board, you must choose between them or add the signals with an SM module.

Frequently asked questions

How do I verify the correct variant?

Compare the full order number 6ES7223-7BF50-0XB0 and the signal type (4x DI / 4x DQ 24 V DC, 100 kHz). A similar name (SB 1221, SB 1223 etc.) is not enough – the variants differ in voltage and speed.

Can several signal boards be used on one CPU?

No, the CPU S7-1200 G2 has one slot for SB, CB or BB. For a larger number of additional signals, use an SM module.

Is the board compatible with the original S7-1200 series?

No. The G2 generation uses its own range of boards with the order number suffix -50-0XB0, which is not interchangeable with the original series S7-1200.

Is mounting difficult, or are special tools needed?

No, the board slides into the front of the CPU under the hinged cover without tools. Replacement takes a few tens of seconds.
