FAQ
Frequently Asked Questions (FAQ)
Q1: What type of signals does the AAI143 module support?
A1: It supports 4 to 20 mA DC analog current signals only.
Q2: Is the AAI143 module channel-to-channel isolated?
A2: No, it is isolated between the input group and the system, but not between individual channels.
Q3: Can the AAI143 module be used in redundant configurations?
A3: Yes, it is compatible with dual-redundant configurations for reliability enhancement.
Q4: What is the power supply requirement for the transmitter connection?
A4: The module supplies 19.0 V or higher at 20 mA and limits output to 25.5 V at 0 mA, with a 25 mA maximum.
Q5: Does this module support HART communication?
A5: Yes, HART is supported when installed in an ER bus node unit with EB401 firmware revision 2 or later.
Q6: What is the typical accuracy of the AAI143 module?
A6: The typical accuracy is ±16 microamperes (µA).
Q7: What are the supported wiring options for external connections?
A7: It supports pressure clamp terminals, MIL connector cables, and KS1 dedicated cables.
Q8: What type of barriers should be used in intrinsically safe applications?
A8: Zener barriers are not allowed. Use only isolation barriers for intrinsic safety compliance.
