Product Description

The NFAI143-H50/CCC01 is a high-performance analog input module engineered for the Yokogawa CENTUM VP integrated control system. This module serves as a critical interface for 4 to 20 mA DC field signals, providing high-density data acquisition with 16 fully isolated channels. The /CCC01 suffix indicates the presence of a conformal coating, making the unit suitable for deployment in harsh industrial environments where corrosive gases or moisture may be present.

By utilizing high-voltage electrical isolation between the input terminals and the internal system circuitry, the NFAI143-H50/CCC01 ensures signal integrity and prevents common-mode noise from affecting the process controller. It is specifically designed for mission-critical loops where reliability and precision are non-negotiable.

Technical Specifications

Module Variants Comparison

While the standard NFAI143 handles basic 4-20 mA signals, the NFAI143-H50/CCC01 includes specific enhancements:

• H50 Suffix: Denotes the standard speed version with high isolation.

• CCC01 Option: Adds a protective layer against corrosion, unlike the standard S1 version which lacks this coating.

• Compatibility: Fully compatible with AAI143 and AAV144 racks depending on the specific terminal block used.

Common Technical Questions

• Question: Is the NFAI143-H50/CCC01 hot-swappable?
  Answer: Yes, this module supports hot-swapping within a redundant or non-redundant configuration when mounted on a compatible FIO bus unit, allowing for maintenance without interrupting the control process.

• Question: What is the benefit of the CCC01 option?
  Answer: The /CCC01 designation confirms the module is compliant with ISA S71.04 G3 standards, protecting the PCB from chemical contaminants found in refineries and paper mills.
