Recommended Upgrade & Replacement Models
Direct replacement: 6ED1052-1FB00-0BA6 (LOGO! 230 RC 0BA6). Hardware‑compatible, function blocks increased to 200, faster execution.
High‑end upgrade: 6ED1052-1FB08-0BA2 (LOGO! 8 series 230RCE). Built‑in Ethernet, supports web server, data logging, MQTT; function blocks up to 400.

The LOGO! 0BA5 series (starting with 6ED1052) is an early smart logic controller line from Siemens, represented by 6ED1052-1FB00-0BA5 (230RC). It covers a full voltage range from 12/24V DC to 230V AC, available in display (RC) and non‑display (RCo) versions to meet various application needs.

This series is discontinued. It is recommended to choose the official upgraded 0BA6 version or the higher‑end LOGO! 8 series for better performance and functionality.
