About the D4-EE-2

The Automation Direct Facts Engineering Koyo D4-EE-2 is an EEPROM memory cartridge. A member of the DirectLogic 405 series, this device interacts with central processing unit (CPU) modules from the same series family. Programmable logic controller CPUs such as D4-440 and D4-450 do not have any integrated system memory and require external memory cartridges. Cartridges like D4-EE-2 provide D4-440 or higher systems with needed system memory. 

D4-EE-2 provides EEPROM memory storage space to logic controllers. This cartridge has 15.5K of available memory to store system programs and data. EEPROM memory can be read an infinite amount of times and can retain all stored memory indefinitely. No cartridge battery is required as power is not needed to maintain the saved memory. The cartridge does have a finite number of times it can be written to, with a life cycle of less than 10,000 writes. The D4-EE-2 cartridge has an electrical memory-clear method. To install into a base, the cartridge fits into the designated memory card slot on the back of the CPU module. After installation, the device is ready to be written and read from.

Following all outlined storage and installation parameters will prevent the cartridge from being damaged. To prolong the life of D4-EE-2, transitional logic, like one-shot, should be used with the device. This allows all data to be written once rather than with each CPU scan. Installation graphics and directions are available in the device user manual and datasheet. 

Frequently Asked Questions about D4-EE-2

What is the D4-EE-2 unit?

The D4-EE-2 unit is a memory cartridge. It has up to 15.5K program storage capacity, with no cartridge battery and a writing life cycle of >10,000. The memory type for this model is EEPROM, which is denoted by the EE within the part number. This model can be mounted in any of the available DirectLogic 405 units that require a memory cartridge.

Are there specific DL405 modules that the D4-EE-2 will be inserted in?

The typical modules in the DL405 family that the D4-EE-2 will be inserted in are either D4-440 or D4-450 modules. The D4-440 module requires a memory cartridge, while the D4-450 module has 7.5K FLASH program memory, but the D4-EE-2 module can be added to allow for more program space.
