01 / PRODUCT IDENTIFICATION
Isolated Analog Input Module
|
| Yokogawa NFAI143-S50 is a STARDOM FCN analog input module with sixteen isolated 4 to 20 mA channels. The S50 execution is the standard non-HART, non-ISA-G3 version. The terminal interface is selected separately, so the installed pressure-clamp block, surge-absorber choice or MIL connector arrangement must be confirmed with the module. |

The removable termination choice forms part of the installed signal path and must not be assumed from the module number alone. |

Five Checks Buyers Should Complete

Only after channel count, signal type, isolation, termination, environmental execution and supported system release are confirmed.
|
| 03 |
NFAI143-S50 S1 - What should be recorded before removal?
Record slot position, terminal assignment, field polarity, connected base or terminal block, and all visible suffix and style markings.
|
| 04 |
NFAI143-S50 S1 - What should be tested after installation?
Verify seating, wiring, power and diagnostics, then commission each affected channel under controlled conditions.
|
| 05 |
NFAI143-S50 S1 - What should be sent with a quotation request?
Send the full catalog code, quantity, required condition, destination and clear photos of the unit label and front connection area.
