product details
YOKOGAWA NFAI143-H00A4S00
Manufacturer: Yokogawa Electric Corporation
Part Number: NFAI143-H00/A4S00
Product Type: Isolated Analog Input Module / HART Communication
System Compatibility: Yokogawa CENTUM VP / FIO, ProSafe-RS, STARDOM, FA-M3 PLC
The NFAI143-H00/A4S00 is a high-density analog input module with 16 fully isolated 4–20 mA DC inputs, designed for seamless integration into Yokogawa CENTUM VP, ProSafe-RS and STARDOM control systems. It simultaneously supports standard analog acquisition and HART digital communication, enabling secondary variable monitoring and device diagnostics without interrupting the primary process signal. Comprehensive technical specifications are presented below.

🔢 Model Code Breakdown: NFAI143-H00/A4S00
The complete ordering code NFAI143-H00/A4S00 segments define specific configuration attributes.
| Model Segment | Code | Description |
| Product Series | NFAI143 | Analog input module (4–20 mA, 16 channels, isolated) |
| First Suffix | -H | HART communication (smart transmitter support) |
| Additional Designator | 00 | Basic type / Standard hardware revision [21†L5] |
| Option Code | /A4S00 | Pressure clamp analog terminal block (NFTA4S-00) – tool‑free field wiring [21†L6] |
| Alternative Option | /A4S10 | Pressure clamp terminal with surge absorber (NFTA4S-10) for lightning protection [21†L7] |
Within the NFAI143 product family, suffix -H denotes HART communication capability, while -S indicates standard analog (non-HART) modules [21†L5]. The /A4S00 termination is designed for applications requiring quick, reliable field connections without screw terminals. For corrosion‑prone environments, /CCC01 adds conformal coating for G3 protection [11†L18–L19], and /A4S10 adds integrated surge suppression [21†L7].
