Sixteen-channel DC input and transistor-output expansion for documented SIMATIC S7-200 CN installations.
Siemens 6ES7223-1BL22-0XA8 is a SIMATIC S7-200 CN EM 223 digital input/output expansion module intended for S7-22X CPUs. It provides sixteen 24 V DC digital inputs and sixteen 24 V DC transistor source outputs in one module.
The complete article number is important because the 0XA8 suffix identifies the S7-200 CN version. Siemens states that this CN product carries CE approval only; replacement decisions should therefore retain the full suffix and verify the installed controller, wiring and approval requirements.

Adds sixteen DC input points and sixteen transistor output points for sensors, switches, indicators, valves and interposing devices.
Supports like-for-like maintenance where the hardware configuration, addressing and field wiring were designed for this exact EM 223 variant.
Useful for restoring legacy control panels after confirming CPU compatibility, I/O allocation, load current and certification requirements.
The Siemens data sheet identifies 6ES7223-1BL22-0XA8 as a spare part. A current official lifecycle category such as Active, Product Cancellation or Discontinued was not verified, so no additional lifecycle status is inferred.
It provides sixteen 24 V DC sink/source digital inputs and sixteen 24 V DC transistor source outputs.
Siemens specifies the EM 223 module for SIMATIC S7-200 S7-22X CPUs.
They are 24 V DC transistor source outputs rated at 0.75 A per channel, not relay outputs.
No. Channel count, output technology, regional version, approvals and wiring must match the installed documentation.
Confirm the full suffix, CPU model, hardware configuration, field wiring, load current, available panel space, condition and approval requirements.
