Thirty-two outputs consolidate a full field-output group in one module identity.
Overview
ADV559-P01 is identified by Yokogawa as an ST4-compatible digital output module with 32 output points and individual isolation for each point.
The P01 suffix is part of the exact basic specification code and must be retained when comparing an installed module, spare or project bill of material.
Selection must also include the node unit, terminal interface, project release and field circuit because the module number alone does not define the complete termination assembly.

Features
Individual point isolation separates field circuits within the documented module architecture.
ST4 compatibility supports controlled modernization of matching legacy I/O arrangements.
Exact P01 coding preserves the intended module variant in maintenance records.
Applications
- Yokogawa control-system digital output service using ST4-compatible field circuits.
- Migration or replacement projects where the installed documentation calls for ADV559-P01.
- Process-control outputs requiring individually isolated points and documented termination.
About IndustryParts
https://www.industryparts.com/Thirty-two isolated outputs remain traceable
IndustryParts records ADV559-P01 with its P01 suffix, node location and field termination so similar ADV modules are not mixed.
- P01 suffix preserved
- Node and slot recorded
- Channel testing requested
Lifecycle
- Record the node, slot, terminal assembly, field voltage and module label before removal.
- Do not substitute ADV559-P00 or another ADV5xx module solely because the point count is similar.
- Apply the Yokogawa isolation and field-circuit checkout procedure during exchange.
- Test every used point and the associated interlocks before returning the loop group to service.
FAQ
Can ADV559-P01 replace an ST4 module without engineering review?
ST4 compatibility is the functional basis, but the project must still verify termination, field power, logic mapping, diagnostics and migration procedure.
What information is needed to quote ADV559-P01?
Send the full module label, node-unit model, slot, terminal interface, field voltage, output type, project release and required quantity.
Is ADV559-P00 interchangeable with ADV559-P01?
Do not assume so. The final specification code is part of the product identity and must match the project documentation or an approved Yokogawa cross-reference.
How should an ADV559-P01 output group be checked after replacement?
Verify point mapping, isolation, field voltage, commanded state, load response, diagnostics and all affected permissives or trips.
What evidence is useful for a tested ADV559-P01?
Request exact suffix photos, visual inspection, per-channel switching results, isolation checks, diagnostic status and traceable test-equipment details.
