The GE Fanuc IC670MDL330 output module is a discrete output module that runs on AC voltage in the range of 12 to 120 Volts AC and that has a current rating of 1 Amp. The GE IC670MDL330 discrete output module is part of the GE Field Control series and it comes with 16 output points. All of the outputs are arranged in a single group and they each have a corresponding LED that lets the users know if a particular output is powered on or off. Either the Bus Interface Unit (BIU) or another part of the Field Control system can perform interface duties for the IC670MDL330 discrete output module. These interface duties include the faults reports and the configuration of the default settings for all of the outputs.

The GE Fanuc IC670MDL330 discrete output module comes with 2 bytes or 16 bits of discrete output data, and the Bus Interface Unit can be used to obtain this discrete output data from the local processor and/or from the host device. The Bus Interface Unit provides the IC670MDL330 discrete output module with its logic power and sends the module its output data in a serial format. During the transmission process, the IC670MDL330 discrete output module will automatically loop the serial output data back to the Bus Interface Unit so that it can be verified. Serial-to-parallel converter devices can also be used to convert this data into a parallel format if the IC670MDL330 module needs the data to be in a parallel format.
