Yokogawa SAI143-H33 Analog Input Module
Technical Specifications:
- Number of channels: 16 isolated channels, which can collect 16 – way analog signals at the same time, and there is no mutual interference between channels.
- Input signal: The rated input is 4-20mA current signal, and the allowable input range is 0-25mA.
- Accuracy: ±16μA, ensuring the accuracy of signal collection.
- Input impedance: When the power is on, the impedance is 250Ω plus the current value; when the power is off, the impedance is ≥500kΩ.
- Voltage drop: About 0.45V, which has little impact on the signal source.
- Data update frequency: 40ms, which can quickly update the collected data.
Detailed content
- Functional Characteristics:
- The isolated design between channels can effectively prevent signal interference and ensure the accuracy of data collection.
- It has a high – precision signal conversion circuit, which can accurately convert analog signals into digital signals.
- The transmitter power supply function can provide a 24V DC power supply for the field transmitter, reducing the number of on – site power supplies.
- It supports online calibration, which is convenient for users to calibrate the module and ensure the long – term accuracy of the module.
- It has a fault self – diagnosis function, which can monitor the module’s own operating status in real – time and send an alarm signal when a fault occurs.
- Application Scenarios: It is widely used in the collection of temperature, pressure, and flow signals in the petroleum and chemical industry; the monitoring of various process parameters in the pharmaceutical industry; and the data collection of environmental monitoring equipment in the environmental protection industry.
