Description

The Yokogawa NFAI135-S51 S2 is an isolated channel analog input module engineered for the STARDOM FCN autonomous controller platform. It features 8 dedicated input channels configured to process 4 to 20 mA DC current signals from 2-wire and 4-wire transmitters. Channel-to-channel isolation delivers robust electrical protection and high signal integrity, effectively mitigating ground loops and field noise in complex industrial processing zones. Equipped with an ISA Standard G3 environmental option, the module is built to withstand corrosive atmosphere variables, making it optimal for long-term reliability in critical process automation frameworks.

Features

Channel-to-Channel Isolation: Employs rigorous electrical isolation between the inputs and the system, as well as between individual channels.
HART Communication Capability: Supports digital field communication overlaid onto standard 4 to 20 mA hardware loops.
ISA Standard G3 Option: Configured with professional environmental protection to counter atmospheric corrosion.
Integrated Overcurrent Protection: Protects sensitive internal circuits against unexpected electrical surges from field line paths.

Applications

Oil and gas exploration and refining facilities
Petrochemical and chemical process plants
Municipal water and wastewater management systems
Power generation system monitoring
Distributed industrial data acquisition networks

Installation Guidelines

Ensure a stable 24 V DC source is linked to the analog field power supply terminal of the power supply module.
Form physical terminations using the corresponding pressure clamp terminal block or a tailored MIL connector cable system.
Note that when using a MIL connector cable like the KMS40, the withstanding voltage limit between input and system drops to 500 V AC for 1 minute.
Avoid coupling Zener barriers to this hardware; specify an isolation barrier for intrinsically safe installation demands.

What does the S2 designation stand for on this module?

The S2 identifier represents Style 2, indicating the specific hardware revision version of the module manufactured by Yokogawa.

Does this module feature channel-to-channel isolation?

Yes, it provides complete channel-to-channel galvanic isolation as well as isolation between the field inputs and the system backend, rated at 500 V AC for 1 minute.

Can I connect a Zener barrier to the input channels?

No, connecting a Zener barrier directly to this module is not allowed. You must use an isolation barrier if implementing it within an intrinsically safe circuit.

What are the configuration constraints indicated by the NFAI135-S51 codes?

The code denotes a standard module type (-S), no explosion protection features (5), and the integration of the ISA Standard G3 conformal coating option (1) for hostile atmospheric environments.
