Product Description
The Yokogawa AAI835-S03 is a 4-channel analog input and 4-channel analog output module designed for industrial control systems. It supports 4-20 mA current signals on both input and output channels, with electrical isolation between channels and between the I/O circuits and the system. This configuration allows the module to handle analog signal acquisition and output control within the same module.

Input and Output Configuration
The AAI835-S03 combines four analog current input channels and four analog current output channels in one module. Each input channel receives a 4-20 mA signal, while each output channel delivers a corresponding current signal to external field devices.
Furthermore, the input and output channels feature electrical isolation. The module also provides 500 V AC isolation between the I/O circuits and the system for one minute, helping limit electrical interference and prevent unwanted signal interaction.
Output Load and Electrical Characteristics
The output channels support load resistance from 0 to 750 ohms. The output leakage current is less than 0.65 mA. Meanwhile, the specified input and output accuracy values are +/-16 uA and +/-48 uA, respectively.
The module requires 360 mA at 5 VDC and 450 mA at 24 VDC. Therefore, both supply conditions should be considered when checking the power requirements of the installation.
Suffix Code Configuration
The AAI835 ordering information defines several configuration options:
| Code | Description |
|---|---|
| -S | Standard type |
| -H | With HART digital communication |
| 5 | Without explosion protection |
| E | With explosion protection |
| 0 | Basic type |
| 3 | ISA Standard G3 option and -20 to 70 deg C temperature option |
The AAI835-S03 suffix identifies the standard type, without explosion protection, with the ISA Standard G3 and extended temperature options. It does not include the HART communication option specified by suffix -H.
Frequently Asked Questions
Q: How many analog input and output channels does the AAI835-S03 provide?
A: It provides four 4-20 mA analog input channels and four 4-20 mA analog output channels, giving a total of eight channels.
Q: Does the AAI835-S03 support HART communication?
A: The supplied ordering information assigns HART digital communication to suffix -H. The AAI835-S03 uses the standard -S configuration, so HART communication is not specified for this model.
Q: What is the temperature range of the AAI835-S03?
A: The suffix 3 specifies the temperature option of -20 to 70 deg C, together with the ISA Standard G3 option.
