ABB 07MC90C1 is a conformal-coated industrial SmartMedia memory card module designed for the Advant Controller 31 and Procontic CS31 series PLCs. It is a harsh-environment enhanced variant of the standard 07MC90 memory card, with a protective coating applied to the PCB and components. This coating provides improved resistance to dust, moisture, condensation, and corrosive gases, making it suitable for use in demanding industrial environments while retaining all the core data storage and backup functions of the original 07MC90 card.

07 represents the Procontic 90 and Advant Controller 31 product series. MC stands for Memory Card, denoting a removable storage module for controller programs and data. 90 refers to the high-capacity industrial-grade memory card variant. C1 indicates the conformal-coated version, enhanced for operation in harsh industrial conditions.

The part number is GJR5252600R0102. It uses industrial-grade SmartMedia flash memory with a storage capacity of 2 MB. The data retention period is a minimum of 10 years at 25 degrees Celsius when unpowered. The operating temperature range is 0 degrees Celsius to 55 degrees Celsius, and the storage temperature range is minus 40 degrees Celsius to 85 degrees Celsius. The protection class is IP20 when inserted into the controller. The overall dimensions are 38 mm × 25 mm × 4.4 mm, and the weight is approximately 10 grams. The product has passed CE, UL, CSA, and RoHS certifications. The conformal coating is applied to the entire circuit board and components for enhanced environmental protection. It is fully compatible with all 07KT9x series CPUs and other AC31/CS31 controllers that support SmartMedia cards.

The module uses the standard SmartMedia interface, which is directly compatible with the dedicated SmartMedia slot on the front panel of AC31 series controllers. It supports plug-and-play operation without requiring additional drivers or software installation. The controller uses a proprietary ABB file system for storing user programs, process data, and firmware updates. A dedicated CARD LED on the controller provides visual status indication for card access and operation. Hot-swap operation is supported, allowing the card to be inserted or removed while the controller is powered on. The card is equipped with a write-protect switch to prevent accidental data modification or overwriting.

The conformal coating provides enhanced protection against dust, moisture, and condensation, ensuring reliable operation in harsh industrial environments. It supports program backup and restore, enabling quick saving and loading of user programs and system configurations. It is used for data logging, storing process data, event logs, and production records for traceability and analysis. It supports recipe management, allowing multiple production recipes to be stored for fast line changeovers. It enables firmware updates, allowing the controller's operating system and firmware to be updated without dedicated programming tools. It provides long-term data retention, securely preserving critical data for up to 10 years without power. It simplifies maintenance, enabling fast and consistent program deployment across multiple controllers.

It is widely used in chemical plants, water and wastewater treatment facilities, food and beverage production lines, and pharmaceutical plants with high humidity or dust levels. It is suitable for packaging machinery, assembly lines, and material handling systems that require frequent recipe changes and program backups in harsh environments. It is ideal for maintaining and upgrading existing Procontic CS31/AC31 installations operating in dusty or humid conditions. It is used in remote and unattended sites such as oil and gas facilities, energy plants, and infrastructure applications where on-site programming is limited and environmental conditions are challenging. It is an essential component for high-availability systems in critical processes, where quick controller replacement with pre-loaded programs is required.

Insert the card into the CPU's SmartMedia slot with the gold contacts facing down, and push until fully seated. Use the write-protect switch on the card to prevent accidental overwriting of critical data. In the Control Builder AC31 software, select the backup to card function to save programs and configuration data. To restore data, insert the card into a new or reset CPU, power on the controller, and select the restore from card function in the software. Inspect the card annually for physical damage, and verify data integrity before making any critical process changes. Replace the card every 8 to 10 years or if read/write errors occur, using only ABB-approved SmartMedia cards. Avoid exposure to direct sunlight, moisture, and corrosive gases, and operate within the rated temperature range. Do not touch the gold contacts on the card, and keep it clean and dry when not in use.
