Yokogawa AAI835-S50 Analog I/O Module

Frequently Asked Questions (FAQ)

Q1: What is the main function of the AAI835-S50 module?
A1: It is a 4-channel analog input and 4-channel analog output module designed for 4 to 20 mA signal handling with isolated channels.

Q2: Is the AAI835-S50 suitable for intrinsically safe applications?
A2: A Zener barrier is not permitted. An isolation barrier must be used if applied in intrinsically safe zones.

Q3: Can the module be used in redundant configurations?
A3: Yes, it supports dual-redundant configurations to enhance system reliability.

Q4: Does the AAI835-S50 support HART communication?
A4: Yes, HART communication is supported, provided the ER bus node unit has EB401 firmware version 2 or later.

Q5: What is the load resistance range supported by the analog output channels?
A5: The output channels support a load resistance range of 0 to 750 Ω.

Q6: What is the data update rate of the module?
A6: The data update period for the AAI835-S50 is 10 milliseconds.

Q7: What type of connection interface does the AAI835-S50 use?
A7: It supports pressure clamp terminals, MIL connector cables, and KS1 dedicated cables.

Q8: What are the dimensions and weight of the AAI835-S50 module?
A8: The module measures 107.5 × 32.8 × 130 mm and weighs approximately 0.3 kg
