The GE Fanuc IC670ALG330 module is a field control module that has 8 output current channels. It is made to connect to 1 power supply that can accommodate 8 different current-loop outputs. Each of the 8 channels on the IC670ALG330 control module is an analog module that is scalable and each channel can be configured by the users. The users specifically can configure the scaling parameters and the output level. The IC670ALG330 module can also be reset to its factory calibration settings because the module’s flash memory stores all of the calibration data. The output currents can be anywhere between 0 and 20 milliamps and they all have 16-bit resolution. The data types that the IC670ALG330 field control module supports are the bit data types and the word data types.

The GE Fanuc IC670ALG330 field control module has alarms for situations like under-range, over-range, and open wire errors. This module only has 1 LED indicator, but this single indicator light can show that the module is powered on and operating properly when it is glowing steadily, that the module is experiencing a fault when it flashes intermittently, and it shows that the module is powered off or that it has experienced a fatal fault if it is not illuminated. The purpose of the IC670ALG330 module is to transmit data. It receives output data in engineering units from a BIU or Bus Interface Unit, it scales this data according to the the parameter settings and calibrations that the users have given it, and it finally converts this data into an output current rated at 0 to about 20.48 milliamps.
