PRODUCT DESCRIPTION
Bring monitored 24 V inputs into a PROFIsafe station
Siemens 6ES7138-4FA03-0AB0 is an ET 200S electronic module for acquiring 24 V digital signals through PROFIsafe. It offers eight single-channel inputs or four two-channel evaluations, with configurable input delay, integrated sensor-supply outputs and local diagnostic indication.
The exact-model datasheet also identifies use in a PROFINET configuration with IM 151-3 HF. Electrical isolation separates the input circuitry from the backplane, while channel-to-channel separation is not provided; sensor selection, station supply and the safety assessment therefore remain important integration checks.

- Confirm FA03 on the complete label rather than selecting by family appearance.
- Check the interface configuration and the actual potential-group power module.
- Compare sensor electrical characteristics and configured input evaluation.

ET 200S PROFIsafe SIGNAL ACQUISITION
Review the station supply before applying the input ratings
The FA03 datasheet identifies a PROFIsafe input module that can also be used with IM 151-3 HF in a PROFINET configuration. Record the actual interface and configured module identity before planning the signal path. Eight single-channel inputs and four two-channel evaluations are different ways of using the hardware, so the engineering project must describe the intended arrangement.
The field-side electrical checks should include sensor output levels, input current and the two protected supply outputs. The input circuit is isolated from the backplane but not between channels or from L+. These distinctions matter when reviewing shared circuit references and external supplies; the 24 V label does not by itself demonstrate that an arbitrary sensor connection is suitable.
Assess the complete potential group rather than reading the maximum safety class as a standalone approval. Siemens explicitly distinguishes the older FA03 when assigning power modules. Keep that table with the safety assessment, and use the exact-model 2015 characteristic information only with its stated repair-time, mission-time and complete-function assumptions. The selected references do not authorize new field wiring.
Features:
- Interface-specific station review
- Shared field-reference assessment
- Power-group safety limitations
The Siemens 6ES7138-4FA03-0AB0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Read the full 6ES7138-4FA03-0AB0 marking before ordering a spare and compare it with the approved station documentation. Keep existing images, labels and configuration records together so that the supplier and maintenance team are discussing the same suffix. The sources reviewed here do not establish an unconditional substitute for this exact article number.
Before replacing the module, compare the existing single-channel or paired evaluation with the documented sensor connections and potential-group supply. Confirm that the replacement retains the input characteristic, protected sensor-supply arrangement and backplane isolation required by the project. These checks are particularly important when a station has been modified since its original validation or when a different power module is proposed.
After the hardware identity has been established, use the applicable original installation and project records to plan commissioning and validation. The 2020 datasheet and 2015 component-characteristic information serve different purposes and should not be treated as a complete wiring manual. Record unresolved interface, safety or documentation questions before release, rather than importing settings from the later FA05 chapter.
Features:
- Suffix-bound spare identification
- Supply and sensor continuity checks
- Original commissioning records required
The Siemens 6ES7138-4FA03-0AB0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7138-4FA03-0AB0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Is this an ordinary eight-channel digital input card?
No. Siemens identifies the exact FA03 as an ET 200S 4/8 F-DI PROFIsafe electronic module. Its single-channel and two-channel configurations are distinct evaluation arrangements. The system configuration and intended safety function must be checked rather than choosing it solely because eight physical inputs are present. -
Can FA03 be used in a PROFINET station?
The exact-model Siemens datasheet explicitly identifies use in a PROFINET configuration with IM 151-3 HF. This does not establish compatibility with every ET200S interface or every engineering-software revision. Compare the installed interface and approved project before changing the station configuration. -
What electrical limits matter when selecting sensors?
Check the published signal thresholds and typical 3.7 mA high-state input current, as well as the sensor-supply voltage and current budget. Each of the two protected supply outputs supports up to 300 mA. The datasheet excludes two-wire sensors, so a two-wire device should not be selected from the voltage rating alone. -
Are all input channels electrically isolated from one another?
No. Siemens states isolation between the input circuitry and the backplane bus, but no channel-to-channel isolation and no separation from the load supply L+. Do not treat the module as eight individually isolated measurement channels when reviewing field-circuit references. -
Does the input-delay range state the machine stopping time?
No. The datasheet's 0.3-17 ms bounds describe configurable input transition delay. They do not describe the complete response of sensors, communication, safety logic and final switching devices. Determine the required complete-function timing from the applicable engineering documentation rather than using this single value. -
Can the maximum safety class be claimed with any power module?
No. The official ET 200S assignment table explicitly limits modules up to FA03 when supplied by PM-E DC24V up to 6ES7138-4CA01-0AA0. Other documented supplies have different limits. The retained original table must be reviewed with the sensor evaluation and complete safety design; the datasheet maximum is not an unconditional application rating. -
How should the 2015 safety-characteristic information be used?
It lists the exact FA03 as a component and provides values under a 100-hour repair-time assumption and a 20-year mission time. Siemens requires adding the contributions of the CPU, I/O, communication, sensors and actuators for the safety function. Those conditions are neither a remaining-life promise for a used unit nor a certificate for the complete machine. -
Why is there no separate installation PDF in this package?
The verified sources provide exact FA03 product data and applicable power-assignment context, but the available later operating manual's detailed input chapter covers FA05. Its wiring and settings have not been transferred to FA03. Obtain the applicable FA03 installation documentation before commissioning or changing field wiring.
