Siemens SIMATIC S7-1200 223-3BD30-0XB0

Siemens SIMATIC S7-1200 223-3BD30-0XB0: documented system role and evidence boundary; verify the individual unit before service, replacement or commissioning.

System role and interfaces

Rebuilt from individual evidence

Unknown: evidence boundary

Manufacturer documentation identifies 223-3BD30-0XB0 as a SIMATIC S7-1200 SB 1223 digital I/O signal board.

Processes two 24 V DC digital inputs and two 24 V DC digital outputs at up to 200 kHz in a SIMATIC S7-1200 station.

At system level, 223-3BD30-0XB0 sits between discrete field devices and the S7-1200 controller logic at the station field-I/O boundary. This sentence is an inference from the cited facts.

Unknown: the individual unit condition, firmware, project configuration, installation compatibility, current stock, price, warranty and service outcome.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
Processes two 24 V DC digital inputs and two 24 V DC digital outputs at up to 200 kHz in a SIMATIC S7-1200 station.
System position
Sits between discrete field devices and the S7-1200 controller logic at the station field-I/O boundary.
Upstream / inputs
Receives discrete 24 V DC field signals and configuration from the S7-1200 station.
Downstream / outputs
Routes high-speed output states from the controller to connected discrete loads.
Limitations
Unknown: the individual unit condition, firmware, project configuration, installation compatibility, current stock, price, warranty and service outcome.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • Manufacturer documentation identifies 223-3BD30-0XB0 as a SIMATIC S7-1200 SB 1223 digital I/O signal board.

    Confidence: high

  • Processes two 24 V DC digital inputs and two 24 V DC digital outputs at up to 200 kHz in a SIMATIC S7-1200 station.

    Confidence: high

Inferences

  • At system level, 223-3BD30-0XB0 sits between discrete field devices and the S7-1200 controller logic at the station field-I/O boundary.

    Confidence: high

    Rationale: The cited identity and documented function establish the component boundary; the system position is stated as an inference rather than as a wiring instruction.

Unknowns

  • Unknown: the individual unit condition, firmware, project configuration, installation compatibility, current stock, price, warranty and service outcome.

    Confidence: low

    Missing evidence: No unit-level inspection, project file, or current commercial record was captured in this individual lookup.
