        Overview Manuals Specifications Control Monitoring Application Scenarios

        Features:

        • Sixteen non-isolated channels for 4 to 20 mA current input signals.
        • Compatible with two-wire transmitters and STARDOM FCN applications.
        • NFTA4S terminal block support and a 40-pin MIL connection interface.
        Reliable acquisition of transmitter signals is essential for stable process monitoring and control. Yokogawa NFAI141-S00 S2 brings sixteen 4 to 20 mA inputs into an FCN-based automation system through one module. Two-wire field transmitters can supply differential pressure and other current-based process measurements to the controller. The non-isolated channel arrangement supports installations where shared module architecture is acceptable. High channel density also reduces the number of input modules required for multi-point measurement applications.

        Wiring flexibility supports both panel assembly and field signal integration. Yokogawa NFAI141-S00 S2 works with the NFTA4S terminal block and provides a 40-pin MIL connector interface. Specified values for open-circuit voltage, short-circuit current, external capacitance, and external inductance help engineers review connected circuits. Such parameters are particularly important when evaluating cable characteristics and transmitter connections. Proper engineering assessment supports dependable signal transmission between field devices and the FCN control node.

        System capacity must be reviewed as part of every I/O configuration. Yokogawa NFAI141-S00 S2 consumes power from both the 5 V DC and 24 V DC supplies, so the combined load must not exceed the power module rating. Installation planning must also follow the stated restriction covering NFAI141, NFAI841, NFAB841, NFAI835, and NFAP135 modules. Operation from -20°C to +70°C and at altitudes up to 2000 m supports a broad range of controlled industrial environments. The supplied 100 m EJA transmitter connection example also demonstrates how the module can be considered for a Class I, Division 2 application when all applicable installation requirements are satisfied.

        The NFAI141-S00 S2 Yokogawa Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Loop Regulation: Provides real-time continuous 4-20 mA current signal feedback for closed-loop precision control of PID control valves.
        • Signal Decoupling: Enables independent acquisition and isolation of multiple sensor signals, preventing electrical interference between channels from affecting control stability.
        • Redundancy Switching: Supports dual redundancy configuration, achieving millisecond-level seamless switching in the event of a main module failure, ensuring control continuity.
        • Safety Interlock: When the input signal triggers a limit threshold, a trip signal is directly sent to the controller to execute an emergency safety interlock.
        • Trend Recording: Real-time monitoring of continuous changes in multiple process parameters, providing operators with high-resolution historical trend charts.
        • Disconnection Detection: Automatically monitors the current status of the input loop, triggering a loop disconnection alarm immediately when the current drops below 4mA.
        • Over-limit Alarm: Provides dynamic monitoring of four alarm limit levels: High-High (HH), High (H), Low (L), and Low-Low (LL).
        • Health Diagnosis: Continuously performs self-checks on the module's internal analog-to-digital converter (ADC) and microprocessor, reporting module faults in real time.
        • Oil Refining and Chemical Industry: Used for monitoring the current signals of pressure and temperature transmitters in reactors and distillation towers.
        • Thermal Power Generation: Used for real-time data acquisition and control of key thermal parameters such as boiler drum water level and main steam pressure.
        • Large-scale Metallurgy: Used for centralized monitoring of blast furnace and converter cooling water flow and pipeline pressure to prevent equipment overheating.
        • Water Treatment Plants: Used for signal integration from water quality monitoring instruments such as flow meters, turbidity meters, and pH meters in inlet and outlet water networks.
        Description
        Process instrumentation can be connected to a STARDOM FCN system through the Yokogawa NFAI141-S00 S2 analog input module. Sixteen non-isolated input channels receive standard 4 to 20 mA current signals, allowing multiple two-wire transmitters to be connected within one module. Each input circuit can handle one compatible field transmitter, including Yokogawa EJA differential pressure transmitters. The channel density helps consolidate process measurements while maintaining a straightforward field wiring arrangement.

        Field connections for the Yokogawa NFAI141-S00 S2 are supported by the NFTA4S terminal block and a 40-pin MIL connector. Electrical parameters include an open-circuit voltage of 26.4 V, a short-circuit current of 27.0 mA, an allowable external capacitance of 0.19 µF, and an allowable external inductance of 10.0 mH. Operating conditions cover temperatures from -20°C to +70°C and installation altitudes up to 2000 m. Such specifications allow engineers to evaluate field wiring and transmitter compatibility before installation.

        Power availability must be checked before adding the Yokogawa NFAI141-S00 S2 to an FCN node. Total I/O module consumption must remain within the rated 5 V DC and 24 V DC output capacities of the installed power supply module. Under the stated installation limitation, only one module among NFAI141, NFAI841, NFAB841, NFAI835, and NFAP135 can be installed when both 5 V DC and 24 V DC current consumption are considered. A documented application example connects one EJA differential pressure transmitter to one NFAI141 input circuit through a 100 m cable in a Class I, Division 2 hazardous area.
