Siemens 6ED1052-2HB08-0BA2 LOGO! 24RCEo logic module without display

Siemens 6ED1052-2HB08-0BA2 is documented for the stated industrial system role: Executes programmed LOGO! logic, processes eight digital inputs, switches four relay outputs, and exposes the documented Ethernet services.

System function

Rebuilt from individual evidence

System position

Siemens identifies 6ED1052-2HB08-0BA2 as LOGO! 24RCEo (AC), a logic module without a display with 24 V DC/24 V AC relay I/O.

Siemens lists 8 digital inputs, 4 relay outputs, 400-block memory, modular expansion, Ethernet, an integrated web server, data logging, microSD, and MQTT for the exact module.

Executes programmed LOGO! logic, processes eight digital inputs, switches four relay outputs, and exposes the documented Ethernet services.

The system position is an explicit inference from the exact-reference evidence.

Unknown: firmware level, loaded program, relay loading, network configuration, and installation-specific compatibility.

System role

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

Function: Executes programmed LOGO! logic, processes eight digital inputs, switches four relay outputs, and exposes the documented Ethernet services.
System position: Sits between field I/O and relay-switched loads as a compact no-display LOGO! controller.
Upstream / inputs: Receives 24 V AC/DC power and the documented digital field signals.
Downstream / outputs: Switches four relay outputs and publishes controller data through Ethernet, web, data-log, and MQTT functions.
Limitations: Unknown: firmware level, loaded program, relay loading, network configuration, and installation-specific compatibility.

Inferences

Inferred system position: Sits between field I/O and relay-switched loads as a compact no-display LOGO! controller.
Confidence: high
Rationale: The exact-reference sources establish the product identity and documented interfaces; their relationship to the stated upstream and downstream elements is marked as an inference.

Unknowns

Unknown: firmware level, loaded program, relay loading, network configuration, and installation-specific compatibility.
Confidence: low
Missing evidence: The individual lookup does not establish the installation, configured software, physical condition, or current commercial record.
