Siemens S7 Series Memory Card for Use with S7-1X00 CPU

Securely store application info and programmes with this memory card from Siemens. It's used with a compatible PLC so that preset instructions can be repeatedly sent to attached bits of machinery. This means the unit's at home working as part of industrial automation, robotic or processing operations. It carries out up to 200,000 write and delete operations per hour without a drop in performance, so you can trust it to handle demanding applications. Due to its memory type, it's suitable for programmes that are read-only.

• Large 256MB memory means you can save high volumes of information
• Dimensions of 32 (H) x 24 (W) x 2.1mm (D) to fit neatly into your PLC module
• Lockable to prevent accidental loss of data

It retains data for 10 years if there are fewer than 20,000 delete and write processes. If these processes are greater than 180,000, data's retained for one year.

Flash EPROM memory is ideal for data storage applications as information is easily logged and rewritten electronically.
