The Intel Atom E3940 runs four cores at 1.6 GHz, paired with 8 GB DDR3L. That's enough to handle a mid-sized machine line with 64 I/O modules plus a server module on a 1-meter rack. Integrated Ethernet switch on the RJ45 port saves a DIN slot and a few bucks per panel. Clock backup holds time for six weeks at 40 °C, so a planned outage won't reset timestamps. The I²t of 0.426 A²·s with starting current inrush tells you the inrush energy; size the 24 V supply with that in mind — a standard 3 A supply works, but the 2.9 A max draw leaves almost no headroom for auxiliary loads on the same circuit. DIN-rail mount, 160 mm wide by 117 mm tall by 75 mm deep. That's a standard space for a 8-slot ET 200SP head station. The four USB ports (two USB 2.0, two USB 3.0) and single DisplayPort are on the front — make sure gland plate clearance allows cable loops. One mode selector switch on the front for run/stop. The SD card slot is optional; main memory is solid-state 8 GB RAM. The integrated 24 V power supply means no external PS module needed, but factor in the 2.9 A budget across the whole rack. Reverse polarity protection built in, so wiring mistakes don't smoke the board. Fast nickel beats slow dime — mount it right the first time.","metaTitle":"Siemens 6AG1677-2DB40-2AA0 CPU, Intel Atom E3940, 8 GB RAM","metaDescription":"Siemens Simatic ET 200SP CPU 6AG1677-2DB40-2AA0 with Intel Atom E3940 1.6 GHz, 8 GB RAM, 24 VDC, 16 W.
