The standard user memory is 4 MB.

The I/O memory is 0.98 MB.

Supports storage expansion through SD card(maximum 2 GB).

Power consumption and heat dissipation:

The power consumption is 2.5 watts.

The heat dissipation is 8.5 BTU/hour.

Operating temperature and storage temperature:

The operating temperature range is 0~60℃.

The storage temperature range is-40~85℃.

Vibration and operating shock:

It has a vibration tolerance of 2 G at 10~500 Hz.

The operating shock is 30 G,and the non-operating shock can reach up to 50 G.

III.Programming and configuration

Programming language:

Supports multiple programming languages,including standard IEC 61131-3 programming languages​​(such as LD,FBD,ST,etc.)and Rockwell Automation’s proprietary RSLogix programming software.

Users can choose the appropriate programming method according to their preferences and skill levels.

Configuration tool:

Provide special configuration tools for configuring and debugging the hardware and software of the controller.

These tools can simplify the configuration process and improve configuration efficiency.
