常见问题 (FAQ)
-
What RTD types are compatible with the AAR145-S50?
The module supports Pt100, JPt100, Cu10, Cu53, and similar standard RTD elements. -
Can I mix RTD and POT inputs on the same module?
Yes, each channel is individually configurable to accept either RTD or POT input. -
Is the module hot-swappable?
No, the AAR145-S50 should only be inserted or removed with the power turned /f to avoid damage. -
Does the module require calibration?
Factory calibration is sufficient in most cases, but periodic verification is recommended for critical applications. -
What are the isolation specifications / the channels?
Each input channel is isolated from every other channel and from ground, enhancing signal integrity. -
What kind / connector does the module use?
The module plugs into a Yokogawa terminal base 件, which provides wiring terminals for field connections. -
Can this module be used with non-Yokogawa systems?
It is specifically designed for Yokogawa systems; integration with other systems is not /ficially supported. -
Is there a s/tware tool for configuration?
Yes, configuration is typically performed through Yokogawa’s engineering tools such as PRM or Control Builder. -
Does the module support HART communication?
No, the AAR145-S50 is an input module for analog signals and does not include HART capabilities. -
What happens if a sensor fails or disconnects?
The module detects open circuits and can flag faults to the control system for operator attention.
