        More Information

        Overview Manuals Input Image Sensor Feed Fault Reporting Module Assembly

        Features:

        • Eight 24 V DC input channels occupy one byte in the ET 200pro process image.
        • Individual sensor feeds support the field devices while the station reports module diagnostic events.
        • The included bus module and separate I/O connection module divide backplane and field-side termination functions.
        Siemens 6ES7141-4BF00-0AA0 concentrates eight binary field states in a sealed ET 200pro electronic-module position.

        Channel LEDs reveal the evaluated input image locally, while the SF indicator directs attention to the diagnostic record rather than an ordinary ON state.

        The field connector pattern is chosen through the compatible connection module, so electronic-module selection and connector-module selection remain separate decisions.

        The Siemens 6ES7141-4BF00-0AA0 SIMATIC ET 200pro 8-Channel Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

        Mapping eight field states into one station byte

        • Bit Order: Channels 0 through 7 occupy the corresponding bit positions of the assigned input byte.
        • Cyclic Transfer: The station interface transfers the evaluated byte to the DP or PROFINET controller.
        • Direct States: Each bit represents one field input and is not combined with the neighbouring channel.
        • Address Choice: The engineering configuration assigns the byte address used by the controller program.

        Supplying and referencing the connected field devices

        • Eight Feeds: A sensor-supply output accompanies each digital input channel.
        • Common Limit: The combined sensor load remains within the module total-current boundary.
        • Two-Wire Devices: Supported two-wire sensors must remain within the permitted off-state quiescent current.
        • Reference Path: The field signal and its supply return use the terminals provided by the selected connection module.

        Separating input activity from a module condition

        • Channel State: Green indicators show the evaluated ON state of the corresponding inputs.
        • Group Fault: The red SF indicator identifies a module diagnostic condition rather than a normal channel transition.
        • Bus Record: The controller can read the diagnostic information through the station interface.
        • Scope: This standard module reports module diagnostics and does not duplicate the channel-specific diagnostics of the High Feature variant.

        Completing backplane and field connections with separate parts

        • Bus Module: The supplied bus module joins the electronic module to the ET 200pro backplane.
        • Field Connector: A compatible I/O connection module is ordered separately for the external cable interface.
        • Mechanical Stack: The electronic module seats between these station-side and field-side connection elements.
        • Selection Check: Connector type and pin assignment are verified against the chosen I/O connection module before wiring.
        Description
        Within a SIMATIC ET 200pro station, Siemens 6ES7141-4BF00-0AA0 is the electronic module that acquires eight 24 V DC field states. The module transfers one input byte to the station interface and keeps the signal connections on the detachable I/O connection module.

        Eight sensor-supply outputs accompany the channels of 6ES7141-4BF00-0AA0. Each input evaluates the corresponding field conductor against its reference potential, while the common supply path supports two-wire sensors within the defined quiescent-current limit.

        Local indications on 6ES7141-4BF00-0AA0 separate normal channel activity from a module-level fault. Green LEDs follow the evaluated input states, and the red SF indication works with the readable station diagnostics when the module reports a fault condition.

        The bus module supplied with 6ES7141-4BF00-0AA0 forms the backplane connection, but the external I/O connection module is a separate component. That division lets the electronic module remain distinct from the M12 or other field-connector arrangement selected for the ET 200pro assembly.

        Technical notes
        Siemens 6ES7141-4BF00-0AA0 brings eight 24 V DC inputs into an ET 200pro station. Its separately ordered I/O connection module defines the external connector layout.

        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.
        VIEW ALL FAQS
        Why is an additional connection module needed with Siemens 6ES7141-4BF00-0AA0?
        Siemens 6ES7141-4BF00-0AA0 contains the input electronics and includes its bus module, while the separately ordered I/O connection module provides the external field connectors.
        How are the eight inputs of Siemens 6ES7141-4BF00-0AA0 represented in the controller?
        Siemens 6ES7141-4BF00-0AA0 transfers channels 0 through 7 as the matching bits of one assigned input byte.
        What should be checked when the SF LED on Siemens 6ES7141-4BF00-0AA0 is red?
        For Siemens 6ES7141-4BF00-0AA0, read the station diagnostic record and check the module supply and sensor-supply path rather than treating SF as an input-state indication.
        May a two-wire sensor be connected to Siemens 6ES7141-4BF00-0AA0?
        Yes. Siemens 6ES7141-4BF00-0AA0 supports two-wire sensors when their quiescent current does not exceed the documented 1.5 mA limit.
        Does Siemens 6ES7141-4BF00-0AA0 provide channel diagnostics like the High Feature version?
        No. Siemens 6ES7141-4BF00-0AA0 is the standard 8 DI module with module diagnostics; the -0AB0 High Feature article has additional channel diagnostic functions.
        Which wiring detail prevents an incorrect connector choice for Siemens 6ES7141-4BF00-0AA0?
        Before wiring Siemens 6ES7141-4BF00-0AA0, match the required M12 or other external interface to the documented 6ES7194-4..00-0AA0 I/O connection module.
