Description
At-A-Glance Executive Brief
- Model: A413077
- Brand: Valmet (Formerly Metso Automation)
- Part Type: FBC2 Fieldbus communication interface module for Damatic XDi and early Valmet DNA DCS
- Lifecycle status: EOL legacy pulp & paper DCS spare; stocked for brownfield pulp, paper mill Damatic XDi rack maintenance
- System compatibility: Metso Damatic XDi, early Valmet DNA distributed control system; acts as fieldbus gateway between DCS rack backplane and fieldbus instruments, transmitting process measurements, valve status and diagnostic data between field devices and NCU2 controller
- Weight: ~0.46 kg
Technical Introduction
Failure of A413077 FBC2 severs fieldbus communications between the DCS controller and all connected fieldbus instruments. Transmitter measurements, control valve feedback, device diagnostics and remote control commands will be lost. Affected pulp or paper process sections lose closed-loop control capability, creating process upset risk, paper web breaks and unplanned mill downtime.
Valmet A413077 FBC2 is a dedicated fieldbus communication module designed for Damatic XDi and early Valmet DNA DCS platforms widely used in pulp and paper mills. This plug-in card serves as the interface between the Damatic XDi rack internal backplane bus and the fieldbus segment. It handles protocol conversion, signal conditioning, bus power supervision and field device diagnostics. The PCB is conformal coated to resist dust, moisture and condensation common in paper mill control rooms. It exchanges real-time process data with the NCU2 controller and supports device alarm and diagnostic reporting for field transmitters, positioners and analyzers. Pulp & paper reliability teams stock A413077 to restore fieldbus instrument communication for Damatic XDi process racks.
- Best Suited For
- Metso Damatic XDi / early Valmet DNA DCS racks in pulp and paper mills
- Fieldbus interface gateway for connecting fieldbus instruments to DCS control nodes
- Direct drop-in replacement for existing Valmet A413077 FBC2 fieldbus communication hardware

Field Engineer’s Tech Notes
- Confirm full part revision, Damatic XDi firmware version, fieldbus segment configuration and device list before replacement; revision mismatch or incorrect bus parameters will cause fieldbus segment communication failure.
- Implement process safety bypass for all fieldbus control loops and interlocks before removing the FBC2 module. Loss of fieldbus communication will disable all associated instrument measurements and valve control.
- Inspect fieldbus cable, bus terminators, shielding and rack backplane connectors; improper bus termination, moisture ingress and cable damage are common causes of intermittent fieldbus faults.
- After installation, verify 24VDC power-up, backplane handshake, fieldbus segment scan and field device detection. Validate measurement acquisition, valve control commands and device alarm reporting, clear faults and remove safety bypass before returning process online.
- ESD protection required while handling PCB assembly.
- Perform fieldbus segment health audit and backup device configuration as part of mill DCS preventative maintenance.
Adaptive QA & Testing Protocol
Each A413077 FBC2 fieldbus module is bench tested on Damatic XDi test rack. We verify 24VDC power boot, backplane bus communication, fieldbus segment scanning, field device emulation and diagnostic LED operation. PCB, edge connector, conformal coating and solder joints are visually inspected for burn marks, corrosion or thermal damage. Full test reports are available upon request.
Buyer’s FAQ
Q: What is Valmet A413077 used for? A: It is the FBC2 fieldbus communication module for Damatic XDi / early Valmet DNA DCS, acting as gateway between rack backplane and fieldbus instruments for pulp & paper process control.
Q: What warranty applies for refurbished and NSFP A413077? A: Refurbished and NSFP units carry a 12-month hardware warranty. Coverage excludes ESD damage, fieldbus surge damage, moisture corrosion, firmware/configuration mismatch and improper safety bypass.
Q: What lead time should I expect? A: Stocked units ship 3–7 business days. If inventory depleted, we source surplus Valmet A413077 FBC2 modules.
Q: Can A413077 be hot swapped? A: Not hot-swappable. Rack 24V control power must be isolated before removal. All critical control loops require safety bypass before replacement.
Q: Is A413077 still in production? A: No, Damatic XDi series including A413077 FBC2 is end-of-life legacy DCS hardware.
