GE Fanuc IC670ALG230K Analog Current Input Module
Description
An 8-channel analog current input module for Field Control systems, supporting 0–20mA/4–20mA ranges and integrating with Bus Interface Units (BIU) for digital conversion.
Features
- 8 grouped current input channels with selectable ranges
- Configurable current ranges: 0–20mA and 4–20mA per channel
- User-defined scaling for engineering unit conversion
- Adjustable high/low alarm thresholds for each channel
- Option to hold last input values or default to 0 on communication loss
