Configure your PLC (programmable logic controller) by storing application programmes and other files within this 8Mb (megabyte) memory card from Siemens. It has a flash EPROM memory type that's used for read-only programmes. The card is electrically erasable and operations can be written and deleted a minimum of 100,000 times. Its compact flash card design is pushed inside the back of a PLC module top-first. The contacts on the back of the card connect with the PLC's electrical current for fast, high-quality data transfer. Its body sits out from the PLC, making it easy to remove when the device is powered down.

• 8Mb of data space provides ample room for simple PLC command programs
• Retains data after final programming for a minimum of 10 years for lasting operation
• Withstands a maximum voltage of 3.3V DC (direct current) for low-voltage use
• Versatile options for use with C7, ET200S and S7-3000 PLCs

Memory cards like this one are commonly found in factory and industrial automation equipment. They're also widely used in the robotics and automobile industries.
