1SAP180100R0001 corresponds to the MC502, an industrial-grade SD memory card designed exclusively for the ABB AC500 PLC series including AC500-eCo, AC500-S and AC500-XC controllers. It serves as a high-capacity storage medium for program backup and restoration, data logging, firmware updates and system configuration storage. Built with industrial flash memory chips, it offers high reliability, fast read/write speed and wide temperature tolerance to meet the demands of harsh industrial environments.

1SAP180100R0001 is the full ABB part number. MC502 is the commercial type designation for the memory card. 180100 represents the base product platform for AC500 series storage accessories, and R0001 indicates the hardware revision. This card is dedicated to AC500 PLC systems and is not compatible with other ABB product lines or standard consumer-grade SD cards.

The card has a storage capacity of 2 GB and uses industrial flash EPROM memory type. It complies with the SD 2.0 standard and supports SPI mode for communication with the PLC. The operating voltage is 3.3 V DC, with a typical operating current of less than 50 mA. The operating temperature ranges from 0°C to +60°C, and the storage temperature ranges from -40°C to +70°C. It supports hot plugging and has a maximum operating altitude of 2000 meters. The protection class is IP20, and it has passed CE and RoHS certifications. The dimensions are 32 mm × 24 mm × 2.1 mm, with a weight of approximately 0.020 kg. It provides reliable data retention for more than 10 years without power supply.

The card adopts a standard SD card interface and connects directly to the dedicated SD card slot on the AC500 CPU module. It communicates with the PLC internal system via the SPI bus, ensuring stable and high-speed data transmission. No additional drivers or external power supply are required. The card supports plug-and-play, and the PLC can automatically recognize and configure it after insertion. Data exchange between the card and the PLC can be completed through ABB Automation Builder software or local operation on the CPU panel.

It enables one-click backup and restoration of PLC user programs, system parameters and configuration data, which greatly simplifies system maintenance and disaster recovery. It supports high-speed data logging of production data, operating status and fault information, which can be used for production analysis and equipment diagnosis. It allows offline firmware upgrade of the PLC CPU and related modules, which can be completed without connecting to a computer. It provides expandable storage space for large-scale application programs and complex control algorithms in AC500 PLC systems.

It is widely used in AC500 PLC-based automation projects such as factory automation production lines, packaging machinery, material handling equipment and building automation systems. It is an essential tool for system commissioning, program backup and regular maintenance. It is suitable for applications requiring long-term data recording and traceability, such as pharmaceutical, food and beverage processing industries. It is also used for batch upgrading of multiple PLC devices in large-scale industrial sites.

Insert the card into the SD card slot on the AC500 CPU module with the correct orientation until it clicks into place. Do not remove the card during data reading or writing to avoid data loss or card damage. To back up or restore programs, use the corresponding functions in ABB Automation Builder or the local menu on the CPU. Keep the card surface clean and dry, and avoid contact with water, oil or corrosive substances. Do not bend, scratch or expose the card to strong electromagnetic fields. The card has no user-serviceable parts. Replace it promptly if data errors or recognition failures occur.
