What this SIPLUS LOGO! variant is
The 6AG1052-1MD00-2BA5 is a SIPLUS version of the standard LOGO! 12/24RC logic module, hardened for an ambient temperature span of -25 to +70°C. Based on the 6ED1052-1MD00-0BA5 base model, it keeps the same 12/24 VDC power supply and relay outputs but adds the extended thermal range that matters when the controller sits in a hot machine cabinet or a cold outdoor enclosure.
