Shipping Port:Jinhua China
Lead Time:1-3 Working Days
Condition: Brand New And 100% Original
Warranty: 12 months

The YOKOGAWA AAI143-H50 is an Analog Input Module designed for use in industrial automation systems by Yokogawa. It converts analog signals from sensors and transmitters into digital signals for processing by a control system.

Input Type: Current Input Module (Isolated) - This means it accepts electrical current signals from sensors or transmitters, typically in the range of 4 to 20 milliamps (mA). The isolation feature helps protect the control system from electrical noise or ground loops.
Number of Channels: 16 - The module can handle analog signals from up to 16 different sensors simultaneously.
Dual Redundancy: The module can be used in a redundant configuration with another AAI143-H50. This provides backup in case one module fails, ensuring continued operation of the control system.
HART Communication: Some sources mention a note about HART communication (*3) in the specifications, though details are unclear. HART (Highway Addressable Remote Transducer) is a communication protocol that allows for advanced configuration and diagnostics of intelligent transmitters.

Input Signal: 4 to 20 mA DC current loop
Allowable Input Current: Up to 24 mA
Input Resistance: Depends on the current flowing (around 250 Ω to 350 Ω)
Accuracy: ±16 μA
Data Update Period: 10 milliseconds
Transmitter Power Supply: Provides power to the connected transmitters (19.0 V or more at 20 mA, 25.5 V or less at 0 mA)
Maximum Current Consumption: 230 mA (5 V DC) or 540 mA (24 V DC)
Weight: Approximately 0.3 kg

Industrial Automation Systems: The AAI143-H50 would be used in various industrial automation applications where sensors provide analog current output that needs to be integrated into a control system. This could include:
Process control systems in industries like oil & gas, chemical, power generation, and manufacturing.
Factory automation systems for monitoring and controlling machinery.
Data acquisition systems for collecting sensor data from industrial processes.
