SIEMENS 6ED1052-1MD08-0BA0

The SIEMENS 6ED1052‑1MD08‑0BA0 meets the needs of small to medium automation tasks — where a full‑size PLC is overkill but relay logic is too basic. It’s ideal for building‑automation, HVAC control, small production lines, water or lighting control, or any application requiring flexible I/O and simple logic. With 8 inputs — 4 of which can be analog — you can connect sensors (temperature, level, flow, etc.) or switches, while the 4 relay outputs allow direct control of actuators, motors, valves or lighting loads. The built‑in display makes configuration and monitoring easy without extra equipment.

Powering from 12–24 V DC gives flexibility for battery‑backed or low‑voltage systems. Thanks to Ethernet connectivity with integrated web server, you can monitor status, data logs and even operate the module remotely — a feature often missing from basic relay panels. For small‑scale automation, this makes the module far more versatile than fixed relay logic or timer‑based circuits. Compared to generic micro‑controllers or DIY relay boards, the Siemens module offers industrial‑grade reliability, standardized I/O, better integration with expansion modules, and easier maintenance — making it a robust, long‑term choice for professional automation in factories, buildings, or utility setups.
