G4F-AD3A

Description

An 8-channel analog input module by LS Electric (series G4F) for PLC systems; supports selectable voltage or current inputs per channel.

The Polar Energy Assessment:

The G4F-AD3A is part of the GLOFA GM/GM4 line of PLC I/O modules. It allows each of its 8 analog input channels to be configured for either voltage input (e.g., 0-10 V, 1-5 V) or current input (e.g., 4-20 mA) via channel switches. The resolution is about 12-bit signed (–48 to 4047 range) giving good precision for industrial analog measurement.

Pros

• Flexible input mode (voltage or current) per channel.
• 8 channels gives moderate density for analog inputs

Limitations

• Input ranges may not cover all sensor types without external scaling (e.g., ±10 V, ±20 mA beyond scope).
• Being an older/harder to source module (depending on region) may affect lead-time.

Typical use cases

• Industrial automation panels where multiple analog sensors (voltage or current) need to interface with a GLOFA/GM4 PLC system.
• Retrofitting analog I/O into an LS Electric G4FU-based system.
• OEM control systems where 8-channel analog input capacity is required and LS ecosystem is used
