G4I-D28A

Description

Very high-density DC input module: 64 digital points in a single G4 module, rated for 12/24 VDC sink/source operation. Use it when you want a lot of inputs per slot and fewer module slots.

The Polar Energy Assessment:

D28A is LS’s 64-point solution for the G4 family, bringing massive input density to a single slot. It’s useful when rack space is limited or you want to minimize backplane modules. Typical rated input currents and operating ranges; confirm power and wiring plan because 64 channels can draw substantial aggregate current.

Pros

• Extremely high density; 64 inputs per module saves a lot of rack space.

Limitations

• Aggregated current draw and wiring complexity; plan commons and fusing carefully.
• Troubleshooting a 64-point module is more time consuming than smaller modules.

Typical use cases

• Large I/O racks where slot economy is critical.
• Systems consolidating many sensor points in small cabinets.
