常见问题 (FAQ)
Q1: What types / signals can ASI133 handle?
A1: The ASI133 supports both current (4–20 mA) and voltage (1–5 V) analog signals per channel.
Q2: Can I mix current and voltage inputs on different channels?
A2: Yes, the module allows per-channel configuration, so each channel can be independently set for voltage or current input.
Q3: Is ASI133 hot-swappable?
A3: Yes, it can be hot-swapped without shutting down the system, provided the DCS/PLC is designed for live replacement.
Q4: What is the accuracy level / this module?
A4: The ASI133 provides a high accuracy / ±0.1% / full scale.
Q5: How do I know if a channel is malfunctioning?
A5: Built-in diagnostics will alert you to open circuits, out-/-range values, or wiring issues.
Q6: Is this module compatible with older Yokogawa systems?
A6: It is primarily designed for CENTUM VP and Stardom platforms. Check with Yokogawa support for legacy compatibility.
Q7: How many modules can I install per system?
A7: The number depends on the CPU and base 件 configuration. Typically, multiple ASI133s can be used simultaneously.
Q8: Does this module require an external resistor for current input?
A8: Yes, an external 250 Ω resistor is commonly used to convert current to voltage for accurate measurement.
Q9: What is the typical response time per input?
A9: The sampling rate is approximately 100 ms per channel, suitable for most control applications.
Q10: Can I use this in hazardous environments?
A10: Yes, the ASI133 is certified for industrial environments but should be paired with appropriate explosion-pro/ enclosures if needed.
