The Siemens 6ED1052-1MD00-0BA6 is part of the LOGO! 8 series of nano-PLCs. It is designed as a cost-effective solution for simple automation and control applications without requiring full PLC programming expertise. The module features 8 digital inputs (I1-I8, with I1-I4 configurable as 0–10 V analog inputs) and 4 relay outputs (Q1–Q4, 8 A max each). A backlit LCD display allows ladder logic programming and real-time monitoring directly on the device. The module operates on 12/24 VDC wide-range power and supports up to 200 internal function blocks, which can be expanded via add-on modules for I/O, communication, and analog processing.
Programming is performed using Siemens LOGO! Soft Comfort software via USB or DLC connection. Drag-and-drop function blocks allow users to configure timers, counters, math operations, PID control, and communication functions, including optional Modbus or SMS modules. Its compact DIN-rail housing (72 × 90 × 55 mm) operates in temperatures from 0 to 55°C and provides IP20 protection, making it suitable for control panels in HVAC systems, lighting, pumps, conveyors, and small industrial machines. Program retention is maintained even without battery backup, ensuring reliable operation after power cycles.
