NFAI143-H50 Yokogawa Analog Input Module

Description

Yokogawa NFAI143-H50 Full Introduction & Technical Specification
Basic Product Information
Brand: Yokogawa (Yokogawa Electric Corporation)
Model: NFAI143-H50
Official full product name: 16-Channel Galvanically Isolated Analog Input Module with HART Communication for CENTUM VP FIO Distributed Control System
Place of origin: Japan
Physical Dimension & Weight Parameters
Overall outline dimension: width 32 mm, height 106 mm, depth 130 mm;
net weight of the single module is approximately 0.24 kg;
the outer shell adopts flame-retardant engineering plastic integrated structure, built-in reinforced circuit board fixed with shock-absorbing structural glue;
standard FIO backplane card slot plug-in installation mode, compatible with DIN rail auxiliary installation;
external wiring supports pressure clamp terminals and MIL aviation cable dual connection modes;
overall module protection grade reaches IP20, designed for indoor control cabinet installation only;
standard single-slot card structure, multiple modules can be densely arranged on the same backplane to save cabinet space.

Electrical Voltage & Current Parameters
Module operating power is supplied by system backplane dual power supply; rated 5 VDC working current is 230 mA, rated 24 VDC working current is 540 mA;
built-in independent transmitter auxiliary power supply range is 24.0 VDC ~ 25.5 VDC, single channel maximum output current is limited to 25 mA, matching 2-wire and 4-wire field transmitters;
standard signal input range is 4–20 mA DC, maximum allowable overload input current is 24 mA;
on-state input resistance is fixed at 250 Ω, off-state input resistance maintains above 500 kΩ;
isolated withstand voltage between input channels and system internal circuit is 1500 V AC for 1 minute;
built-in independent overcurrent protection circuit for each channel to avoid component burnout caused by short-circuit access;
HART communication baud rate is fixed at 1200 bps, compatible with HART 5, HART 6 and HART 7 mainstream protocols;
internal circuit insulation grade is Class B.
Environmental Adaptation Parameters
Normal continuous operating temperature range: -10 ℃ ~ +60 ℃;
short-term allowable peak operating temperature range: -20 ℃ ~ +65 ℃;
storage and transportation temperature range: -40 ℃ ~ +85 ℃;
applicable ambient humidity range: 5% ~ 95% non-condensing relative humidity;
temperature drift is controlled within ±0.01% per degree Celsius, effectively reducing measurement deviation caused by ambient temperature change;
electromagnetic compatibility complies with IEC 61000 series industrial EMC standards, with strong suppression ability for electrostatic discharge, power surge and high-frequency harmonic interference;
vibration resistance meets IEC 60068-2-6 standard, adapting to slight long-term mechanical vibration of industrial cabinet operation environment.
