The GE-Emerson IC670ALG330 Field Control Analog Output Module provides eight channels of analog current outputs with user-configurable scaling for each channel. The module requires a separate source of power for the outputs. 

A single LED indicator shows module status:

  • ON: normal operation
  • Intermittent flashing: module fault
  • OFF: no backplane power, no user power, or fatal fault

During operation, the module receives engineering units output data from the Bus Interface Unit (BIU). It scales this data according to its calibration and configured scaling parameters, then converts the data to output current in the range of 0mA to approximately 20.48mA. 

If the scaled data is below the minimum limit of the digital to analog converter, the module sets the output current to 0mA. If the scaled data is above the maximum limit of the digital to analog converter, the module sets the output current to approximately 20.48mA.
