The IC670ALG240 is a high-density analog input module for the GE Fanuc Field Control architecture. It mounts directly on a Bus Interface Unit (BIU) or expansion base and provides 16 independent, isolated current input channels for precise process measurement.
Each channel features a dedicated 16-bit ADC, converting low-level field signals into high-resolution digital data with minimal noise, enabling reliable data acquisition in complex industrial control loops.

The IC670ALG240 includes robust internal self-checks:
Monitors A/D conversion health and calibration validity
Detects underrange/overrange conditions per channel
Alerts for individual channel high/low alarms
Ensures early detection of sensor failure or line breaks
These features help maintain system uptime and ensure high-quality, reliable data for control and safety systems.
The IC670ALG240 is widely used for:
Process monitoring of flow meters, pressure transmitters, and liquid level sensors
Bridging signals from VFDs or single-loop controllers to central control logic
Integration of analytical instrumentation such as turbidity or chemical sensors
High-precision industrial monitoring loops requiring current-based inputs
Does this module support voltage inputs?
No. The IC670ALG240 is optimized for current inputs. Voltage measurement requires a separate voltage input module from the IC670 series.
Is calibration required upon installation?
The module is factory-calibrated. Internal diagnostics continuously monitor calibration status and will alert the operator if data is missing or out of range, ensuring consistent, reliable measurement.
