Sales Original Germany Siemens 6ES7952-1AL00-0AA0 SIMATIC S7-400 2MB RAM Memory Card For S7-400 PLC CPU In Stock
6ES7952-1AL00-0AA0 is the original German long-form RAM memory card exclusively developed for Siemens SIMATIC S7-400 PLC series, with 2MB industrial SRAM storage capacity. It is the essential storage carrier for S7-400 CPU, which is used to store user control programs, hardware configuration parameters, production process data and system firmware files. Cooperated with S7-400 backup lithium battery (6ES7971-0BA00), it can completely retain all project data after the main power supply is cut off, effectively avoiding production line shutdown losses caused by program data loss. Adopted high-reliability industrial-grade storage chip, it supports stable operation in a wide temperature range of -25℃ to +70℃, with excellent anti-vibration and anti-electromagnetic interference capabilities, and can operate continuously for a long time in various harsh industrial automation scenarios. It supports one-click program upload and download, project backup migration and CPU firmware upgrade, which greatly facilitates daily equipment maintenance and technical debugging. We supply brand new factory-sealed original Siemens spare parts with sufficient spot inventory, professional after-sales technical support, 12-month quality warranty and global fast delivery service.
