I/O Modules Status Indicators

PointMax I/O modules include status indicators such as SA power, LA power, module status, and I/O channel status to indicate module operating conditions and behavior. Not all I/O modules include an SA power status indicator. Some modules, such as AC I/O modules, include an LA power status indicator. For more information about these indicators, see PointMax I/O System Specifications Technical Data, publication 5034-TD001.
For detailed, module-specific status indicator information, see the module user manual listed in the Additional Resources.
