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.
