YOKOGAWA NFAI543-H00 Current Output Module
Description
The YOKOGAWA NFAI543-H00 Current Output Module is a component of the CENTUM VP series distributed control system (DCS), designed for industrial process control applications. Its core function is converting digital signals to analog signals to drive field actuators such as control valves and frequency converters. As a 16-channel analog output module, it delivers 4-20mA output signals, enabling simultaneous analog control signal supply to multiple devices. Each channel is isolated from others, effectively reducing signal interference and enhancing overall system stability. The “H” in its model indicates integrated HART protocol support, which facilitates digital communication with compatible devices, enabling remote monitoring and parameter configuration.
Key technical specifications include: 24V bus voltage and DC24V power supply; monitoring current of ≤1mA (bus) and ≤6mA (power), operating current of ≤4mA (bus) and ≤35mA (power); non-polar two-wire connections for both controller and power supply; total output capacity of DC24V/1A across two groups; output control via pulse or level signals, with relay normally open/closed passive contacts and 10-second relay pull-in time for pulse activation. It has an operating environment range of -10 to 55 degrees Celsius, relative humidity ≤95% without condensation, IP30 protection rating, and dimensions of 110mm×86mm×43mm with base casing. Factory settings default to two-channel normally open line detection mode.
