FOXBORO 0399143 I/A Series Module

The FOXBORO 0399143 I/A Series Module is a power/current transducer module of the Foxboro SY-039914x module family used in Foxboro I/A Series RTU (Remote Terminal Unit) and Foxboro SCADA stations. Its adjacent family members are documented in Schneider Electric's official PSS 41S-2S6KSWR — SY-0399140 (1 Amp Module) and SY-0399142 (5 Amp Module Assembly, 3-Phase AC Transducer) — placing the 0399143 within the same module assembly / AC-transducer series.

1. Confirm the exact function and rating of the 0399143 against the RTU system documentation — family ratings vary (1 A / 5 A documented for adjacent codes).
2. De-energize the RTU station before handling; follow ESD precautions.
3. Install the module in its designated slot in the RTU / transducer assembly per the station layout.
4. Verify CT (current transformer) wiring and phase connections to the transducer input.
5. After power-up, verify the measured values and scaling against the station database before returning to service.

1. How do we know its family? Schneider Electric's official PSS 41S-2S6KSWR documents the adjacent codes SY-0399140 (1 Amp Module) and SY-0399142 (5 Amp Module Assembly, 3-Phase AC Transducer), establishing the family role.
2. Is it a control module? Some supplier listings describe it generically as a "control module" — the family evidence points to a power/current transducer module assembly instead. Verify against RTU documentation.
3. Which system does it belong to? Foxboro I/A Series RTU / Foxboro SCADA (now Schneider Electric).
