Siemens LOGO! 12/24 RCEo Logic Module 6ED1052-2MD08-0BA3

The Siemens LOGO! 12/24 RCEo is a compact logic module from the LOGO! 8.3 series, designed for basic automation tasks. It operates on 12/24V DC and features 8 digital inputs (4 configurable as analog), 4 relay outputs, and an Ethernet interface for communication. This base module does not include a display, making it ideal for cost-sensitive applications where remote monitoring is sufficient.

Advantages

Flexible input configuration allows adaptation to various sensor types. Integrated web server and cloud connectivity enable remote access and data logging. Expandable up to 24 DI, 20 DO, 8 AI, and 8 AO via expansion modules. Real-time clock with automatic daylight saving adjustment ensures accurate time-stamping.

Suitable for

• Small-scale automation in building services (lighting, HVAC, shading)
• Machine control in industrial environments
• Educational and training setups for PLC programming
