Product Description

The 2ME904901 is a robust application memory module designed for advanced industrial automation systems. It features 64 KB of SRAM and 256 KB of FlashPROM, operating with the PCC software system and compatible with processor modules CP10x, CP2x0, and MP100. This module is C-UL-US listed, ensuring compliance with safety standards.

To enhance reliability and data integrity, the 2ME904901 includes a lithium battery (3V / 950 mAh, model number 0AC200.9) with a lifespan of at least two years and a gold foil capacitor that provides buffering for a minimum of 10 minutes. The innovative design allows for battery replacement without shutting down the PCC, although B&R recommends changing the battery when the PCC is not powered due to varying international regulations. The gold foil capacitor ensures that RAM is buffered during the battery change, provided the PCC has been powered on for at least five minutes prior to the change and the battery is replaced within 10 minutes after shutdown. For programming, the module is equipped with a FlashPROM programming logic, indicated by an LED display. A write protection switch prevents accidental data writes or deletions, ensuring the integrity of stored data. The front panel includes a battery cover, a programming LED, and a removal lever for easy access and maintenance.

The 2ME904901 can operate in a wide temperature range of -20 to +70 C without the lithium battery, and -20 to +60 C with it installed. It can be stored for up to three years at 30 C with the battery not installed, and operates reliably in 0 to 95% non-condensing humidity conditions. In summary, the 2ME904901 offers exceptional performance, safety, and ease of maintenance, making it an ideal choice for industrial automation systems requiring reliable memory and data protection.
