FAQ
Frequently Asked Questions (FAQ)
Q1: What type of signals does the AAI841 module handle?
A1: The AAI841 handles both input and output signals in the range of 4 to 20 mA DC. It supports 8 channels for input and 8 channels for output.
Q2: Is the AAI841 module isolated?
A2: No, the AAI841 is a non-isolated analog I/O module.
Q3: Can the module be used in redundant configurations?
A3: Yes, the AAI841 supports dual-redundant configurations when used with appropriate node units.
Q4: Does the AAI841 support HART communication?
A4: Yes, HART communication is supported for current input and output when used with ER bus node units and EB401 firmware revision 2 or later.
Q5: What is the maximum load resistance allowed for analog outputs?
A5: The allowable load resistance for each analog output channel is from 0 to 750 Ω.
Q6: What are the environmental requirements for using the transmitter power supply?
A6: The transmitter power supply provides 14.8 V minimum at 20 mA and 26.4 V maximum at 0 mA. Voltage drop due to wiring should be considered in system design.
Q7: Is the input mode configurable per channel?
A7: Yes, each input channel can be configured for either 2-wire or 4-wire transmitters using setting pins.
Q8: What precautions must be taken when using the module in intrinsically safe environments?
A8: Zener barriers must not be used with the AAI841. Only isolation barriers are acceptable for intrinsically safe applications.
