The Field I/O module with catalog number IC670ALG330 is a Current source analog output module. It is manufactured by GE Fanuc Automation, featuring Eight (8) output channels that provides 0-20 mA output range. Being part of the Field I/O series, the IC670ALG330 is typically used as component of a Remote I/O topology.

The IC670ALG330 has output resolution of 16 bits to each channel with 14-bit magnitude data size. It has typical output accuracy of 0.05% while the maximum accuracy is 0.1% @ 25 Degree Celsius and o.15% from 0 - 50 Degree Celsius. This module presents an analog output resolution of 0.3125 5µA per count which is the maximum resolution. It has output load capacitance of 2000 pF and output load inductance of 0.5H. The IC670ALG330 analog output module exhibits an update time of 1.5 mS and capable of detecting an open wire output measured between 1.0 mA - 3.5 mA current threshold.

The IC670ALG330 requires an external supply voltage to operate. It accepts an input supply voltage range of 18-30 VDC with 24 VDC nominal value and maximum ripple of 10%. It features a 1500VAC for 1 minute and 250 VAC continuous ground and logic isolation. The IC670ALG330 has maximum current draw from the Bus Interface Unit (BIU) amounting to 85 mA while current draw from the external power supply amounts to 250 mA, maximum.

The IC670ALG330 is provided with an internal module diagnostic bit that can be used by the programmer to detect module problems. Module diagnostic byte is located at Byte 0, assigned for Module not calibrated (Bit 0), Calibration Data Out of Range (Bit 1), Calibration Write failure (Bit 2), BIU Timeout (Bit 3), Invalid Command (Bit 4), No factory calibration (bit 6) and User supply not detected (bit 7).

The GE Fanuc IC670ALG330 module is a field control module that has 8 output current channels. Each channel on the IC670ALG330 is scalable can be individually configured. Configurable parameters include parameter scaling and output level. The IC670ALG330 module can also be reset to its factory calibration settings. 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 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.
