G4F-DA3I

Description

8-channel current (I) analog D/A module for LS Electric GLOFA G4/GM4 PLCs; outputs standard 4–20 mA loops. Converts 12-bit signed digital values to analog current outputs for process actuators.

The Polar Energy Assessment:

The G4F-DA3I provides eight isolated current output channels (DC 4–20 mA) with 12-bit conversion resolution, intended for direct control of 4–20 mA actuators, valves and drives from G4-series PLCs. It’s part of the G4F analog output family.

Pros

• 8 channels of standard 4–20 mA outputs for medium-density analog control.
• 12-bit conversion resolution gives adequate precision for most process tasks.
• Manufacturer documentation and cut sheets available for wiring and isolation guidance.

Limitations

• Current-only outputs (no voltage mode); use DA1A/DA2V/DA3V if voltage outputs are needed.
• Requires attention to load wiring and external supply rules per LS installation notes.

Typical use cases

• Driving 4–20 mA actuators, control valves, or current-type input devices from a G4/GM4 PLC.
• OEM control panels built on the LS G4 platform requiring multiple current loops.
• Retrofits where replacing discrete analog controllers with PLC-driven control is desired.
