FOXBORO P0400VE Legacy Analog IO Module 4-20mA Fieldbus Card

Key Features

• Legacy analog I/O / fieldbus interface card for the Foxboro I/A Series DCS
• Supports 4–20mA analog field signals (transmitters, valves, loop controllers)
• Fieldbus-connected I/O module with channel-level signal isolation
• Reduces ground loops, EMI, and transient noise on analog loops
• Designed for continuous process control in harsh industrial environments
• Hot-swap capable when installed in compatible I/A Series bases

• Accuracy: ±0.1% FS typical (module-class, configuration dependent)
• Operating Temp: –20°C to +70°C (industrial grade)
• Humidity: 5–95% RH, non-condensing
• Mounting: I/A Series baseplate / DIN-mounted FBM carrier

Installation Notes

1. Verify the exact P0400VE revision and firmware label against your existing I/A Series rack before purchase or swap.
2. Confirm 4–20mA loop wiring, termination assembly, and fieldbus node address before insertion.
3. De-energize or use controlled hot-swap procedure per site maintenance rules.
4. Seat the module in the correct FBM base slot; do not mix with incompatible FBM generations.
5. Restore power and check OK/FAULT LEDs, then validate analog readings in the CP before returning the loop to service.
