XGF-AW4S

Description

4-channel 2-wire analog input module supporting voltage and current ranges with per-channel configuration; designed for process transmitters and mixed-signal cabinets. It exposes data in selectable digital formats to the PLC.

The Polar Energy Assessment:

The AW4S is a 4-channel 2-wire analog input card (4–20 mA primary example) with selectable input ranges per channel and multiple digital output formats (signed, precise, percentile). Offset and gain are handled according to module parameters and PLC scaling; the manual documents wiring, recommended shielding, and timing characteristics for reliable HMI/control behavior.

Pros

• Per-channel range selection for mixed transmitter sets.
• Compact 4-channel layout with straightforward configuration via the platform tools.

Limitations

• As a 2-wire input module it follows 2-wire transmitter wiring rules; check power/wiring for passive loops.
• Per-channel conversion timing matters for very fast sampling; check the manual if you need faster than typical process rates.

Typical use cases

• Process transmitters (4–20 mA) for pressure, flow, level or temperature transmitters using transmitters with 2-wire loops.
