+86 181501176854-Input 4-Output Analog I/O Module · Yokogawa CENTUM Field Control Unit I/O
Yokogawa AAI835-S00 S2 is an isolated current input and output module for compatible CENTUM field control units. It combines four 4-20 mA input channels and four 4-20 mA output channels in one module.
AAI835-S00 S2 provides isolation between the field side and system side and between individual channels. The documented 10 ms data-update period supports coordinated analog measurement and output control, while dual-redundant configurations are supported in an approved I/O arrangement.
The -S00 ordering code identifies the standard type and must not be treated as a HART version. Verify the complete AAI835-S00 S2 style, terminal or cable interface, output load, field power, redundancy arrangement and host software before commissioning.

Yokogawa AAI835-S00 S2 provides four isolated 4-20 mA inputs and four isolated 4-20 mA outputs for analog measurement and control in a compatible CENTUM field control unit.
Yokogawa AAI835-S00 S2 isolates the field circuits from the system and isolates each channel from the others, so channel grounding and field-power arrangements must follow the approved wiring design.
Yokogawa AAI835-S00 S2 has documented input accuracy of +/-16 microA, output accuracy of +/-48 microA and a 10 ms data-update period under the specified operating conditions.
Yokogawa AAI835-S00 S2 supports a documented output load from 0 to 750 ohm, and the complete loop resistance and available field voltage must be verified before commissioning.
Yokogawa AAI835-S00 S2 is the standard -S type, so HART communication must not be assumed; an approved -H ordering code and compatible system configuration are required for HART functionality.
Yokogawa AAI835-S00 S2 supports a dual-redundant configuration when the paired modules, terminal hardware, field wiring and host engineering configuration follow Yokogawa requirements.
Provide the complete Yokogawa AAI835-S00 S2 nameplate, style and revision, terminal or cable connection, redundancy requirement, loop load, host system, quantity and destination.
Send the complete model, revision, quantity, destination and nameplate photo so the exact hardware identity can be checked.
