Product Description:
The 2ME910.90-1 is a controller module produced by B & R Automation for the System 2010 Controllers series. It is intended to coordinate machine sequences by executing stored application code and retaining critical data for industrial automation equipment such as packaging and material-handling stations. Integrated logic memory and on-board buffering help the unit preserve user information during brief power interruptions so that controlled processes can continue with minimal disruption. This arrangement supports dependable operation in applications where stored logic and retained values must remain available after short supply disturbances.
The module stores firmware and application code in 256 KByte FlashPROM, while dynamic variables reside in 64 KByte SRAM. FlashPROM is programmed directly in the module, eliminating the need for an external programmer, and a front-mounted LED serves as the programming indicator. The SRAM section is supported by a lithium battery rated at 950 mAh. The battery delivers its charge at 3 V, matching the memory backup requirements without overloading the circuitry. Configuration data can be protected by an on-module write-protection switch, which helps prevent accidental overwrites during updates or routine operation. Lithium chemistry is used because its low self-discharge is well suited for long standby periods in control hardware.
In normal operation, the lithium cell can hold user RAM for at least 2 years, while a separate gold foil capacitor maintains registers for at least 10 minutes during short outages. The housing measures 122 mm deep, 103 mm high, and 32 mm wide, allowing dense rack installation inside System 2010 cabinets. An LED display on the front panel confirms program status, and in-module FlashPROM programming allows software updates without removing the board from its mounting position. The combination of retained RAM support and short-term capacitor buffering helps the controller ride through brief interruptions without losing active register contents.
