    The SDM-AO4A module increases the number of continuous analog outputs available to a datalogger. These outputs are used for proportional control or driving strip charts.

    SDM-AO4A Benefits

    • Increases the number of CAO ports available to the datalogger
    • Supports both ±5 V and 0 to 10 V modes allowing the module to be used in more applications
    • Includes a choice of synchronous and sequential operation
    • Provides high resolution and high accuracy
