Siemens 6AG1138-4FA04-2AB0 SIPLUS F-DI PROFIsafe module

Siemens 6AG1138-4FA04-2AB0 SIPLUS F-DI PROFIsafe module is documented for the stated industrial system role.

System function

Rebuilt from individual evidence

System position

The Siemens-copyrighted data sheet identifies 6AG1138-4FA04-2AB0 as a SIPLUS F-DI 24 V PROFIsafe module with eight digital inputs and two encoder-supply outputs.

The module receives safety-related digital input signals from field devices in a distributed safety I/O station.

The system position is an explicit inference from the exact-reference evidence.

Unknown: current unit condition, installation-specific compatibility, firmware or software version, and commercial availability.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
The module receives safety-related digital input signals from field devices in a distributed safety I/O station.
System position
Inferred system position: the module sits between safety field inputs and the safety controller path.
Upstream / inputs
Receives documented signals or control data from the Safety field sensors and switches.
Downstream / outputs
Transmits or supplies the documented function to the safety controller path.
Limitations
Unknown: current unit condition, installation-specific compatibility, firmware or software version, and commercial availability.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The Siemens-copyrighted data sheet identifies 6AG1138-4FA04-2AB0 as a SIPLUS ET200S F-DI 24 V PROFIsafe module with eight digital inputs and two encoder-supply outputs.

    Confidence: high

    • adegis.com — retrieved 2026-09-11; high confidence

  • The module receives safety-related digital input signals from field devices in an ET200S safety station.

    Confidence: high

    • adegis.com — retrieved 2026-09-11; high confidence

Inferences

  • Inferred system position: the module sits between safety field inputs and the ET200S safety controller path.

    Confidence: medium

    Rationale: The exact-reference sources identify the component function and the connected system context; the intervening position is explicitly marked as an inference.

Unknowns

  • Unknown: current unit condition, installation-specific compatibility, firmware or software version, and commercial availability.

    Confidence: low

    Missing evidence: The individual lookup does not capture an installed-unit inspection, complete configuration record, or current commercial record.

System position diagram

A system diagram places Siemens 6AG1138-4FA04-2AB0 SIPLUS F-DI PROFIsafe module between the Safety field sensors and switches and the safety controller path, with the placement marked as an inference.

Reading limit: system position only, not a wiring or safety drawing.

The documented component receives data or power from the Safety field sensors and switches and serves the safety controller path; the chain position is an explicit inference.

Recipient and data disclosure

Named recipient: Ardkor human-qualification queue (internal local preview). No partner delivery is enabled here.

Data retained for this review: reference, selected route, location, technical context, contact details, consent state, and any accepted private attachment.

Response expectation: none is promised. If external routing is enabled later, the partner name, disclosed fields, and response expectation must be shown and accepted again.

Withdrawal and deletion: use the private request controls from the receipt to withdraw further processing or request access/deletion. The request remains recorded until the relevant Ardkor systems and any recipient confirm completion.

Read the privacy information before sending. For corrections, access, or deletion help, use the contact page or email reference@ardkor.org; mailbox delivery and attendance have not been verified.

This routing state is separate from watch, marketing, payment, and analytics choices. If no capable service match is found, the request remains a human-qualification lead and is never presented as provider acceptance.
