Description
The Yokogawa NFAI841 appears to be an analog input/output (I/O) module used in industrial automation systems for collecting and transmitting analog signals. Here’s a breakdown of its potential function and how to find more information about it:
Function:
- The Yokogawa NFAI841 likely functions as a module that connects to a control system and allows it to:
- Read analog sensor signals: It can convert voltage or current signals from sensors like pressure transmitters, temperature sensors, or flow meters into digital data the control system can understand.
- Output analog control signals: It can convert digital control signals from the control system into voltage or current signals that can be used to control actuators, valves, or other devices.
Possible Features (depending on model variant):
- Number of Channels: The NFAI841 might have several ch
- annels (typically 4 or 8) for handling multiple analog signals simultaneously.
- Input/Output Type: It can be configurable for voltage input (e.g., 0-10V) or current input (e.g., 4-20mA), and voltage or current output depending on the application.
- Communication Protocol: May use a communication protocol like Modbus RTU or HART to transmit data to the control system.
- Isolation: Electrical isolation between input and output channels and the control system can be a feature for safety and noise reduction.
- Calibration: Methods for calibrating the module to ensure accurate conversion of analog signals.
