Allen Bradley 1784-SD1 programmable controller plc

The 1784-SD1 card is an Allen-Bradley/Rockwell Automation 1 GB secure digital (SD) card. The ControlLogix secure digital card is made for the Allen-Bradley 5570 processor and it features a high level of performance. This ensures minimal development time and costs when it comes to commissioning and normal operation. The 1784-SD1 card has the ability to perform the standard and safety controls in the same chassis for a truly integrated system. It enables the users the ability to leverage a high level of availability and extreme environment capabilities that meet the application requirements. The 1784-SD1 card is an accessory component type with the module-specific functionalities of a 1784 memory card. The maximum ambient operating temperature is rated at 70 degrees Celsius, while the minimum operating temperature is -25 degrees Celsius.

For storage, the 1784-SD1 card should be stored in an environment with a maximum temperature of 85 degrees Celsius and a minimum temperature of -40 degrees Celsius. The recommended maximum ambient relative humidity is 95%, non-condensing. The unit features a maximum vibration acceleration rating of 2 G, while the vibration frequency at operation should not exceed 500 Hertz. The 1784-SD1 card allows the users to keep a copy of the project being worked on on the controller. Therefore, in case of power failure, the data is safe and it can be retrieved from the SD card. The 1784-SD1 card uses the Fat 16 file system and it does not have to be formatted when storing a project to the controller. Therefore, it is quick and easy to deploy the SD cards that are ideal for use in critical environments.
