The Siemens LOGO! 12/24 RCEO (6ED1052-2MD08-0BA2) is a compact logic module designed for versatile control and automation tasks. Operating on 12/24 V DC, it provides eight digital inputs—four of which can also function as analogue inputs (0–10 V)—and four relay outputs rated up to 10 A. The module features an integrated Ethernet interface, web server, micro-SD card slot, and data-logging functionality. Supporting up to 400 program blocks and a real-time clock, it enables efficient and reliable control for small automation systems, offering easy expandability through additional I/O modules.
Ideal for small automation tasks in building management, HVAC control, lighting systems, water treatment, and machine automation. Its Ethernet interface and modular expandability make it suitable for both standalone control and integration into larger industrial or commercial automation networks.
