API4380-G 直流至直流变送器

Main features:

Wide input and output range: The API 4380 G accepts a wide range of DC voltage and current inputs, including 0-50 mV to 0-10 V, +/ -50 mV to +/ -10 V, and 0-1 mA to 20 mA. It offers equally diverse DC voltage and current outputs for flexible signal conversion.

Field configurable: The input and output ranges of the module can be field configured with external rotary and slide switches. Allows users to customize the operation of the transmitter to meet specific application requirements.

Full 3-terminal isolation: output and power supply to ensure signal integrity and eliminate ground loop problems. API 4380 G at the input, this isolation protects the module from electrical noise and interference, ensuring reliable operation in harsh industrial environments.

Loop Power Supply: This module provides a built-in 18 VDC unregulated loop excitation power supply capable of powering passive input devices such as thermocouples and RTDS.

LoopTracker® LED indicator: API 4380 G contains two LoopTracker® leds, one for input and one for output. The strength of these leds varies with changes in process input and output signals, providing a visual indication of signal levels for quick troubleshooting.

Functional test button: The functional test button allows the user to manually start a fixed output level, independent of the input signal. This function helps verify the operation of the transmitter and perform calibration procedures.

Applications:

API 4380 G DC-DC isolated transmitters are used in a wide range of applications, including:

Signal isolation: Isolating signals between different parts of the system to eliminate ground loops and prevent noise interference.

Signal conversion: Converting a signal from one range or format to another, such as converting a thermocouple voltage to a standard 4-20 mA current signal.

Signal amplification: Amplification of weak signals to usable levels for monitoring or control.

Process monitoring: Monitoring various process parameters, such as temperature, pressure flow and level, in industrial plants and machinery.

Data acquisition systems: Collect and process data from sensors and sensors in industrial automation and control systems.
