Features:
- Analog Input and Output Module for the documented Yokogawa STARDOM FCN.
- Channel Arrangement: 4 inputs and 4 outputs.
- Signal Range: 4 to 20 mA.
NFAI835-S51 belongs to the Yokogawa STARDOM FCN and performs the documented analog input and output module role in the Yokogawa STARDOM FCN autonomous controller. The retained technical evidence records Channel Arrangement: 4 inputs and 4 outputs; Signal Range: 4 to 20 mA; Isolation: Channel-to-channel isolated. The full marking, receiving hardware, connectors or terminals, configuration dependencies and installed position must be matched before substitution.
For installation, retain the Yokogawa STARDOM FCN receiving position, connector or terminal arrangement and configuration record. After power restoration, review diagnostics and test the affected operating path before process release.
The NFAI835-S51 Analog Input and Output Module is supplied only after the complete hardware identity, condition and current OEM lifecycle status have been confirmed.
NFAI835-S51 Yokogawa product documentation and selection resources.
Important Notice: The PDF documents NFAI835-S51 or its verified Yokogawa product family. Confirm the complete suffix code and installed-system requirements before replacement.
Loop Function: NFAI835-S51 performs the analog input and output module function within the Yokogawa STARDOM FCN. The retained documentation identifies channel arrangement as 4 inputs and 4 outputs; apply that value only to this documented execution.
Match the complete label, hardware form and functional position before transferring any setting, cable or termination from the removed unit.
Hardware Fit: approve NFAI835-S51 only for the documented Yokogawa STARDOM FCN autonomous controller. Compare rack, carrier or panel generation, connector keying, terminal numbering and all paired assemblies with the installation drawings.
Photograph both sides and the installed position before removal so revision markings, jumpers, addressing and channel allocation can be reconstructed accurately.
Service Checks: isolate the equipment, remove stored energy and inspect the receiving hardware before installing NFAI835-S51.
Restore power in the approved sequence, review status and diagnostics, then test every affected control, signal, relay, communication, protection or monitoring path against the commissioning record.
