G4F-DA1A

Description

An analog D/A (digital-to-analog) output module with 2 output channels, capable of both voltage (±10 V) and current (4-20 mA) signals.

The Polar Energy Assessment:

The G4F-DA1A is designed for use with LS Electric’s GLOFA/GM4 PLC systems to convert digital values into analog outputs. The 2-channel configuration allows dual analog output paths (voltage or current). According to LS’s catalogue, it supports output ranges of DC –10~+10 V and DC 4-20 mA.

Pros

• Dual mode output (voltage and current) gives flexibility in analog interfacing.
• Higher precision output module suitable for control systems that require analog actuation.

Limitations

• Only 2 channels, which may not be sufficient for larger analog output requirements.
• Older module: may have longer lead times or fewer spares available.
• As typical for analog modules, careful grounding/wiring required to avoid noise issues.

Typical use cases

• Driving analog actuators, valves, or transducers requiring ±10 V or 4-20 mA from a LS Electric PLC rack.
• OEM control panels built on GLOFA/GM4 architecture where analog output is needed.
• Retrofitting existing LS Electric systems needing replacement analog output modules.
