The coating also qualifies the card for environments with salt spray (ISA-71.04 level LC3) and oil mist (level LB3), so it belongs in cement plants, chemical processing, or any panel where airborne grit and condensation eat uncoated electronics. ## Temperature range and altitude derating — the real operating envelope Rated for 0 °C to +60 °C ambient at normal atmospheric pressure (1 140 hPa to 795 hPa, corresponding to -1 000 m to +2 000 m altitude). Above 2 000 m the max ambient drops by 10 K per altitude band — at 5 000 m the ceiling is +40 °C — so if the cabinet sits at elevation, budget the derate into the thermal design. ## Memory and system fit for S7-400 racks 2 MB RAM card — the S7-400 CPU uses this as load memory for program blocks and data; the RAM type means the contents are volatile and reloaded from the CPU's memory card or programming device on power-up. Compatible with all S7-400 rack types that accept the standard memory card form factor — the SIPLUS variant is a drop-in replacement for the standard 6ES7952-1AL00-0AA0 in any slot the CPU expects a RAM card.","metaTitle":"Siemens 6AG1952-1AL00-4AA0 SIPLUS S7-400 RAM Card, 2 MB","metaDescription":"SIPLUS S7-400 RAM card with conformal coating, 2 MB memory, 0 to +60 °C range.
