It is an EEPROM-based cartridge, offering battery-free program retention and electrical memory clear as described in the DL405 documentation. The package contents list the D4-EE-2 cartridge itself, with a 15.5K maximum program storage capacity for DL405 configurations. AutomationDirect currently classifies the D4-EE-2 as retired\/discontinued, with no direct replacement listed, reflecting obsolescence of this EEPROM cartridge within the DirectLOGIC DL405 family. For proper use, this cartridge is intended exclusively for DL405 CPUs (D4-440 or D4-450) in accordance with the official cut sheet and DL405 user manuals. \u003c\/p\u003e\u003c\/div\u003e","brand":"AutomationDirect","offers":[{"title":"New","offer_id":46274450424042,"sku":null,"price":238.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-075.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/automation-direct-d4-ee-2-eeprom-memory-cartridge","provider":"GTG Hardware","version":"1.0","type":"link"}
