Siemens Memory Card For Use With S7-1X00 CPU, 12Mb Flash-EPROM Memory - SIMATIC Series - 6ES7954-8LE03-0AA0
Safely store application programmes and other files with this memory card from Siemens. It's designed for use with a PLC (programmable logic controller) that sends commands to machinery in factory automation, robotics and automotive applications. The card is a flash EPROM (erasable programmable read-only memory) type, which means it's for read-only programs. With its compact dimensions of 4 (W) x 32 (H) x 2.1mm (D), it's easy to install top-first inside the back of a PLC module. The contacts on the back of the card connect to the PLC's electrical current for fast and high-quality data transfer. Its body sits out from the PLC, so it can be removed easily when the device is turned off.
• 12MB of data capacity gives you sufficient room for PLC command programs • Made for use with an S7-1X00 CPU (central processing unit) for easy compatibility
