Features:
- 8-Channel Analog Input Module for the documented Yokogawa STARDOM FCN.
- Input Channels: 8 isolated channels.
- Signal Range: 4 to 20 mA.
NFAI135-S51 belongs to the Yokogawa STARDOM FCN and performs the documented 8-channel analog input module role in the Yokogawa STARDOM FCN autonomous controller. The retained technical evidence records Input Channels: 8 isolated channels; Signal Range: 4 to 20 mA; Isolation: Channel-to-system 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 NFAI135-S51 8-Channel Analog Input Module is supplied only after the complete hardware identity, condition and current OEM lifecycle status have been confirmed.
NFAI135-S51 Yokogawa product documentation and selection resources.
Important Notice: The PDF documents NFAI135-S51 or its verified Yokogawa product family. Confirm the complete suffix code and installed-system requirements before replacement.
Input Processing: NFAI135-S51 performs the 8-channel analog input module function within the Yokogawa STARDOM FCN. The retained documentation identifies input channels as 8 isolated channels; 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.
System Alignment: approve NFAI135-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.
Validation Steps: isolate the equipment, remove stored energy and inspect the receiving hardware before installing NFAI135-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.
