That extra headroom on the low end matters when the panel sits in an unheated substation or a cold-weather skid; the 70 °C ceiling holds the CPU on the grid even when the enclosure is cooking next to a steam line or a hot process vessel. ## ATEX and CE for hazardous-area deployment The ATEX marking and CE mark are the regulatory backbone here: this CPU can be installed in Zone 2 / Zone 22 gas and dust atmospheres, provided the enclosure meets the relevant protection concept. The CE mark confirms conformity with the applicable EU directives — a prerequisite for any plant in the European Economic Area. ## Compact 40 mm footprint for tight panels At 40 mm wide, 125 mm tall, and 130 mm deep, this CPU occupies one slot in the S7-300 DIN-rail profile — the same footprint as the standard 314. It mates with the standard backplane bus; no adapter or spacer is needed. The 24 VDC power supply connects via the front-panel connector; the MPI/DP port (RS 485) and the optional CP interfaces (up to 4 via CP, 10 LAN CPs, 8 PtP CPs) plug into the same rack.","metaTitle":"Siemens 6AG1314-1AG14-7AB0 S7-300 CPU","metaDescription":"Siemens 6AG1314-1AG14-7AB0 S7-300 CPU with FM 8, CFC, FBD, LAD, SCL, STL, GRAPH.
