More Information

Overview Manuals I/O Channels Variant Match Loop Checkout Product Applications

Features:

  • Input capacity: four isolated analog input channels.
  • Output capacity: four isolated analog output channels.
  • Signal standard: documented for 4-20 mA loops.
AAI835-S00 S2 combines four analog inputs and four analog outputs in one Yokogawa module.

Because AAI835-S00 S2 handles both measurement and command paths, a replacement review should keep the slot, field-terminal arrangement and loop assignments together.

Apter Power can support AAI835-S00 S2 service work with exact-label review and legacy sourcing.

Apter Power supports documentation review, procurement planning and quotation for Yokogawa model AAI835-S00 S2, an Analog Input/Output Module.

  • Input capacity: four isolated analog input channels.
  • Output capacity: four isolated analog output channels.
  • Signal standard: documented for 4-20 mA loops.
  • Combined role: measurement and command functions share one module.
  • Model: housing label reads AAI835.
  • Suffix: -S00 remains part of the required identity.
  • Style: S2 should be preserved in the receiving record.
  • Slot context: field terminal and system assignment complete the compatibility review.
  • Input test: apply known current values and compare the host reading.
  • Output test: command safe values and verify loop current.
  • Isolation review: check unexpected common or ground paths.
  • Final proof: confirm alarms, scaling and automatic-control response.
  • Process measurement: receives up to four documented 4-20 mA field signals.
  • Analog command: provides up to four 4-20 mA output channels.
  • CENTUM maintenance: supports exact-suffix replacement within the installed I/O node.
  • Loop commissioning: enables channel-by-channel proof after module exchange.
Description
AAI835-S00 S2 combines four analog inputs and four analog outputs in one Yokogawa module. The supplied housing label confirms the AAI835 model, -S00 suffix and Style S2, while Yokogawa documentation defines the channel format as isolated 4-20 mA I/O.

Because AAI835-S00 S2 handles both measurement and command paths, a replacement review should keep the slot, field-terminal arrangement and loop assignments together. This provides a much clearer compatibility check than relying on the AAI835 family name alone.

Apter Power can support AAI835-S00 S2 service work with exact-label review and legacy sourcing. Before return to automatic control, we recommend checking each input against a known source and each output through the connected loop so the restored module behaves like the documented installation.

Technical notes
For AAI835-S00 S2 support, Apter Power recommends preserving the complete label, installed interface and application record. These details help our engineering and commercial team provide a more accurate quotation and a smoother commissioning path.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What does AAI835-S00 S2 provide in a Yokogawa system?
It combines four isolated 4-20 mA inputs and four isolated 4-20 mA outputs, allowing one module to serve both measurement and command loops.
Why should the -S00 and S2 markings be retained for AAI835-S00 S2?
The suffix and style identify the exact build shown on the supplied unit. Recording them helps avoid an overly broad family-level substitution.
What should be documented before exchanging AAI835-S00 S2?
We recommend capturing the slot, terminal arrangement, channel list, loop scaling and any active diagnostics before the module is disconnected.
How can the input side of AAI835-S00 S2 be commissioned?
Inject known current values within the approved range and compare the engineering-unit reading, alarm thresholds and channel quality in the host system.
How can the output side of AAI835-S00 S2 be verified safely?
Use a controlled test value that is suitable for the connected process, then confirm measured loop current and final-device response with operations coordination.
What can Apter Power provide for AAI835-S00 S2?
We can assist with exact-variant review, sourcing, logistics, documentation and quotation support for this discontinued Yokogawa module.
