6ES7223-5BH50-0XB0 – SIMATIC S7-1200 G2, SM 1223 – 8x DI 24 V DC / 8x DQ 24 V DC transistor 0.5 A, Siemens

6ES7223-5BH50-0XB0 is a second-generation SM 1223 expansion module for the Siemens SIMATIC S7-1200 G2 with 8x DI 24 V DC / 8x DQ 24 V DC transistor 0.5 A.

The SM 1223 module combines 8 digital inputs 24 V DC and 8 transistor digital outputs 0.5 A in one housing – saving space in the switchboard compared with a combination of two separate modules.

Key advantages
Increases the number of inputs/outputs without replacing the CPU.
Mounted on a standard 35 mm DIN rail directly next to the CPU or another module.
Channel status diagnostics via LEDs on the module and in TIA Portal.
Compatible with all CPUs of the SIMATIC S7-1200 G2 series (1212C and 1214C, including fail-safe FC variants).

Net weight 0.21 kg
Mounting 35 mm DIN rail
Operating temperature −20 to +55°C, non-condensing
Standards and approvals CE, UL, cULus; developed according to IEC 61131
Typical applications

The module is used wherever the integrated I/O on the CPU S7-1200 G2 can no longer cover the number of signals required by the machine or process unit.

Which assembly it belongs to

The SM 1223 module is part of the assembly Siemens SIMATIC S7-1200 G2. The number of modules that can be connected to the CPU depends on the CPU type (1212C to 6, 1214C to 10 SM/CM). Before ordering, verify the number of remaining slots in your configuration.

Frequently asked questions

How do I verify the correct variant?

Compare the full order number 6ES7223-5BH50-0XB0 and the signal type (8x DI 24 V DC / 8x DQ 24 V DC transistor 0.5 A). Models SM 1221 to SM 1233 exist in several variants differing in the number of channels and output type – a similar name is not enough.

Is the module compatible with all CPUs S7-1200 G2?

Yes, the module can be used with any CPU of the S7-1200 G2 series (1212C and 1214C, including fail-safe FC variants) within the maximum number of modules supported by the given CPU.

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

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

How many of these modules can be connected to the CPU?

It depends on the CPU type: 1212C supports up to 6 SM/CM modules in total, 1214C up to 10. The number is reduced by each communication module (CM) used.
