Description
Product Introduction & Engineering Value
When a process depends on accurate analog control, output stability matters just as much as controller performance. The GE IC670ALG310 delivers eight isolated voltage outputs that allow a Field Control station to drive actuators, valve positioners, variable frequency drives, and other analog-controlled equipment with high resolution and repeatable accuracy.
Each output channel can be configured independently, allowing different scaling and output ranges within the same module. This flexibility makes the IC670ALG310 well suited for distributed control systems where multiple analog devices must be managed from a single remote I/O station.

Field Application & The “Trench” Experience
A refinery modernization project required several remote valve actuators to be upgraded while keeping the existing PLC program intact. The engineering team installed an IC670ALG310 in the Field Control station to replace an aging analog output module. Because each channel could be individually configured for the required voltage range, the original control strategy remained unchanged. Commissioning was completed within the scheduled shutdown, and loop tuning required only minor adjustments after startup.
Typical applications include:
- Boiler combustion air damper positioning
- Chemical dosing skid control using proportional valves
- Variable frequency drive speed reference in water treatment facilities

The Veteran’s Tech Trap Guide
⚠️ Remember That This Module Needs External Output Power
The IC670ALG310 requires a separate user power source for its analog output circuitry. A healthy backplane does not guarantee active voltage outputs if the external supply is missing.
⚠️ Verify Scaling Before Startup
Each channel supports independent engineering-unit scaling. Incorrect scaling can cause valves or drives to receive an incorrect command even though the measured output voltage appears normal. Always compare the configured engineering units with the receiving device specifications.
PRO TIP: After replacing a module, perform a loop check at 0%, 25%, 50%, 75%, and 100% output. This quickly identifies wiring errors, incorrect scaling, or calibration drift before the process is placed into automatic control.
Dynamic FAQ
Q1. What is the primary function of the ?
The converts digital values from the controller into eight isolated analog voltage outputs for controlling field instruments and final control elements.
Q2. Which output voltage ranges are available?
Each channel can be configured for 0–10 VDC or -10 to +10 VDC, depending on the application requirements.
Q3. Can every channel be configured independently?
Yes. Each of the eight channels supports its own output range and engineering-unit scaling, allowing mixed analog control applications within one module.
Q4. Does the module support calibration?
Yes. The supports field recalibration, and calibration values are stored in onboard Flash memory, eliminating the need to recalibrate after every power cycle.
Q5. How are refurbished modules tested?
Each unit undergoes model verification, analog output accuracy testing, isolation verification, diagnostic testing, connector inspection, and functional testing across all eight output channels before shipment.
Q6. Are New Surplus units still available?
Yes. The remains available from specialized suppliers as New Surplus and professionally Refurbished inventory. Availability depends on current stock because the GE Field Control platform is a mature legacy automation system.
