The Siemens LOGO! Contact 230 Switching Module, model 6ED1057-4EA00-0AA0, is a high-performance expansion module designed to extend the output capacity of LOGO! logic controllers. This unit features four independent relay outputs, each capable of switching 230 V AC/DC loads up to 5 A (resistive), making it ideal for controlling contactors, motors, valves, and lighting systems in small to medium automation systems. With its robust electrical isolation and built-in surge protection, the module ensures reliable operation in industrial environments with high electrical noise. The compact form factor integrates seamlessly with LOGO! 8 base modules, supporting both local and remote I/O expansion. Each output channel includes a green LED for visual status feedback, simplifying troubleshooting. The module is fully compliant with CE, UL, and cUL standards, guaranteeing global acceptance. Below are the detailed technical specifications derived from the Siemens product database.
