Description
The GE Fanuc IC670ALG320 is a 4-channel analog output module designed for the Field Control I/O system. This module converts digital control signals from a host processor into precise analog current or voltage outputs, facilitating the control of industrial actuators, regulating valves, dampers, and positioners. It is widely utilized in process automation environments, including power generation, oil and gas, and chemical manufacturing, where high-resolution signal stability is required.
Features
- Four independent sourcing channels for current or voltage output.
- Configurable output ranges: 0-20 mA, 4-20 mA, 0-10 VDC, and 0-12.5 VDC.
- 12-bit digital-to-analog conversion resolution.
- Integrated EMI filtering and ground isolation to protect signal integrity against electrical noise.
- Front-panel LED indicators for monitoring field power and backplane bus status.
- Configurable via external jumper links on the terminal block or internal register adjustment.
Applications
This module is suitable for applications requiring precise analog control, such as modulating control valves, variable frequency drive (VFD) speed references, and position control for industrial actuators. It is compatible with Field Control and Rx7i PACSystems architectures.

Installation Guidelines
- Ensure the system power is disconnected before installing or removing the module from the carrier.
- Use instrumentation-grade shielded twisted-pair cabling to minimize susceptibility to electromagnetic interference.
- Verify that the external 24 VDC power supply is within the 20-29 VDC range and meets the ripple requirements.
- Configure output ranges using the appropriate jumper settings on the terminal block assembly before applying power.
- Maintain proper ventilation in the enclosure to manage thermal dissipation, which can reach up to 4.3 Watts.
- Ensure the module is installed in a clean, dry environment free from conductive dust and liquid ingress.
FAQ
Is this module compatible with all Field Control systems?
The IC670ALG320 is designed for the Field Control I/O series and is also compatible with specific Rx7i PACSystems architectures. Please verify your specific rack and Bus Interface Unit (BIU) compatibility before installation.
How do I change the output range?
The output range can be modified by adjusting the external jumper links located on the mounting terminal block assembly or by configuring the internal registers via a handheld programmer.
