Yokogawa SAI143-S53/A4S10 Analog Input Module

FAQ

Q1: What is the maximum input signal range supported by the SAI143-S53/A4S10 module?
A1: The module supports a 4–20 mA current input signal, with an extended measurable range from 1 to 23 mA for accuracy calculation.

Q2: How many channels are isolated in this analog input module?
A2: All 16 channels are fully isolated to prevent cross-channel interference and ensure reliable signal measurement.

Q3: What is the response time of the module for updating data?
A3: The data update frequency is 40 milliseconds, ensuring fast and accurate signal processing for process control.

Q4: What is the input impedance characteristic when the module is powered off?
A4: When powered off, the input impedance is at least 500 kΩ, minimizing current leakage and preventing signal distortion.

Q5: How does the module handle temperature variations?
A5: The temperature drift is ±16 µA per 10°C, maintaining high accuracy under typical industrial temperature fluctuations.

Q6: What is the maximum voltage the module can withstand between input and system?
A6: The module can withstand 1.5 kV AC for 1 minute between the input signal and system for transient overvoltage protection.

Q7: Can this module provide power to field transmitters?
A7: Yes, it provides a transmitter power supply of 16.15 V minimum (at 20 mA) and 26.4 V maximum (at 0 mA).

Q8: What types of external connections are supported by this module?
A8: It supports pressure clamp terminals, MIL connector cables, or a dedicated KS1 cable, providing flexibility in system integration.
