Yokogawa AAI835-S00 Analog I/O Module

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the AAI835-S00 module?
A1: The AAI835-S00 serves as a dual-function analog I/O module, handling both 4-channel analog inputs and 4-channel analog outputs for 4–20 mA signals, with full channel isolation.

Q2: Does this module support HART communication?
A2: Yes, the AAI835-S00 supports HART communication when installed in an ER bus node unit with EB401 firmware revision 2 or higher.

Q3: Can the AAI835-S00 be used in a redundant configuration?
A3: Yes, it supports dual-redundant configurations by installing two identical modules side-by-side in odd-even numbered slots.

Q4: What kind of isolation does the module provide?
A4: It offers 500 V AC isolation for 1 minute between inputs/outputs and the system, and also between individual channels.

Q5: What is the allowable load resistance for analog output channels?
A5: Each output channel can drive loads from 0 to 750 Ω under standard environmental conditions.

Q6: How accurate is the module’s measurement and output capability?
A6: The input accuracy is ±16 µA, and the output accuracy is ±48 µA, ensuring reliable analog signal handling.

Q7: What are the temperature-related specifications?
A7: The temperature drift is within ±16 µA per 10 °C, making the module suitable for a wide range of operating environments.

Q8: What types of connectors are available for field wiring?
A8: Supported external connections include pressure clamp terminals, MIL connector cables, and dedicated KS1 cables.
