FAQ

AAI835-S00 S2 Function, Configuration and Replacement FAQ

What does AAI835-S00 S2 do?＋

AAI835-S00 S2 is a Yokogawa analog I/O module that exchanges 4–20 mA signals with a compatible field control station. Its configuration is four isolated analog inputs plus four isolated analog outputs, and it must be used only with matching Yokogawa node, terminal and wiring hardware.

How many channels does AAI835-S00 S2 provide?＋

AAI835-S00 S2 provides eight mixed analog channels: four 4–20 mA input channels and four 4–20 mA output channels, with isolated channels. It is not an eight-input-only or eight-output-only module, so the I/O allocation must match the configured control database.

Does AAI835-S00 S2 include HART communication?＋

AAI835-S00 S2 carries the -S standard-type suffix, while Yokogawa identifies -H variants for digital HART communication. Therefore HART capability must not be assumed for AAI835-S00 S2; confirm the full order code and project requirement before substitution.

Which terminal hardware can be used with AAI835-S00 S2?＋

AAI835-S00 S2 can be paired with supported Yokogawa isolated-analog terminal arrangements such as ATI3S or ATI3D, or with ATK4A/ATB3A adapter paths and the applicable KS cable and terminal board. The selected hardware determines transmitter wiring options, so the existing terminal assembly must be verified.

Where is AAI835-S00 S2 installed?＋

AAI835-S00 S2 is installed as field I/O in compatible Yokogawa ESB-bus node units or field control units. Compatibility depends on the exact node or FCS model, system release, slot assignment, terminal hardware and configured 4–20 mA channel database.

Can another AAI835 style replace AAI835-S00 S2 directly?＋

AAI835-S00 S2 should not be replaced solely by matching the AAI835 base code. The -S00 suffix, S2 style, firmware or system-release support, terminal block or adapter, redundancy arrangement and channel wiring must all match the installed configuration.

What must be checked before installing AAI835-S00 S2?＋

Before installing AAI835-S00 S2, confirm the complete nameplate, S2 style, compatible node or FCS, 4–20 mA input/output assignments, terminal block or adapter, KS cable, two-wire or four-wire transmitter arrangement, redundancy requirement, grounding and the saved control-system configuration.
