FAQ
Frequently Asked Questions (FAQ)
Q1: What type of signals does the AAI835-H00 module handle?
A1: The AAI835-H00 module handles analog current signals in the range of 4 to 20 mA for both input and output.
Q2: Is the AAI835-H00 module equipped with HART communication capability?
A2: Yes, it supports HART communication, including variable data collection via HART Command #3.
Q3: Are the input and output channels electrically isolated?
A3: Yes, each input and output channel is isolated from the system and from other channels.
Q4: What is the acceptable load resistance for the analog output?
A4: The module supports a load resistance of 0 to 750 Ω. For ambient temperatures between 60–70°C, it supports 200 to 750 Ω.
Q5: Can the module be used in dual-redundant configurations?
A5: Yes, it is designed to be used in dual-redundant configurations for improved reliability.
Q6: What happens when an open circuit is detected in an output channel?
A6: An open circuit condition is identified if the current falls below 0.65 mA, enabling fault detection.
Q7: What is the recommended transmitter power supply specification?
A7: The module supplies 15.0 V or higher at 20 mA and up to 29.3 V at 0 mA to support 2-wire transmitters.
Q8: Is the use of Zener barriers allowed with the AAI835-H00?
A8: No, Zener barriers are not allowed. Use isolation barriers when required in intrinsically safe applications.
