That means it's built for environments where airborne contaminants or condensation are a risk, not just a clean control cabinet. ## Temperature range and what it buys you The 70 °C ceiling is the operating limit; the conformal coating helps keep moisture and conductive dust off the board at the high end. The 24 V DC supply needs to stay between 20.4 V and 28.8 V — a tight window that means the panel's power supply should be set for 24 V nominal and not drift under load. At that voltage, the module draws 800 mA without the backplane bus and USB loads, so budget the total current including the bus and any USB peripherals you plug in. ## Network and storage fit Three Industrial Ethernet ports: two on X1 (ERTEC-based, 10/100 Mbit/s) for a line or ring topology, and one on X2 for a separate network segment or a service connection. No PROFIBUS onboard — this is a pure PROFINET node. The 2 GB flash disk holds the firmware and project, and the 256 KB non-volatile memory keeps retentive data safe across power cycles. Two USB 2.0 high-speed/high-current ports are available for a service stick or a keyboard during commissioning — they're not for production I/O, but they save you cracking the panel open to update firmware. ## Panel space and thermal budget The module measures 160 mm wide by 125 mm tall by 115 mm deep — it's a wide unit, so check the DIN-rail space in your enclosure. It dissipates 34 W typical, which is non-trivial for a sealed panel; if you're stacking several of these, factor the heat into your enclosure cooling calculation.","metaTitle":"Siemens 6AG1677-1DD00-4BA0 SIPLUS S7 mEC EC31, -40 to 70°C","metaDescription":"SIPLUS S7 mEC EC31 spare part for medial exposure, conformal coating, based on 6ES7677-1DD00-0BA0.
