        Features:

        • Sixteen 24 V DC outputs are paired across eight M12 sockets.
        • Each output switches up to 0.5 A, with 4 A allowed across the module up to +55 °C.
        • PROFIBUS diagnostics, green channel LEDs and a red SF display separate output and module states.
        Siemens 6ES7142-3BH00-0XA0 converts PROFIBUS DP process data into sixteen field switching signals for solenoids, DC contactors or indicator lamps.

        Two channels share each M12 connector, aligning their signal pins with the same 2M and protective-earth references.

        The separately ordered connection block completes bus and load-power entry while the I/O module provides the channel electronics and indication.

        The Siemens 6ES7142-3BH00-0XA0 ET 200eco output module may remain available for quotation, documentation and connection-block review after OEM cancellation.

        Paired M12 Channel Layout

        • Sockets X1 to X4: Each connector carries one channel from the lower group and one from channels 8 to 11.
        • Sockets X5 to X8: The remaining connectors pair channels 4 to 7 with channels 12 to 15.
        • Signal pins: Pins 2 and 4 carry the two output signals assigned to each socket.
        • Reference pins: Pin 3 is 2M and pin 5 is PE across all eight connectors.

        Current Flow to Field Loads

        • Load voltage: The output stage switches the 24 V DC load supply toward the commanded device.
        • Per-channel limit: Each channel is rated for 0.5 A at the active output state.
        • Module limit: Combined output current must remain within 4 A up to +55 °C.
        • Shared potential: The output channels are not isolated from one another inside the module.

        Bus Data and Output Update

        • Bus entry: The ET 200eco connection block passes PROFIBUS DP data to the I/O electronics.
        • Rate range: The module follows station transmission rates from 9.6 kbit/s to 12 Mbit/s.
        • Output image: Received process bits drive the corresponding sixteen output stages.
        • Electrical boundary: PROFIBUS remains isolated from the internal output circuitry.

        Channel, Group and Station Checks

        • Point state: A green LED shows the command state of each individual output.
        • Group condition: The red SF indicator marks a module-level fault.
        • Controller detail: Readable diagnostics provide the fault information over PROFIBUS.
        • Alarm boundary: The module reports diagnostics but does not issue process alarms.
        Description
        Siemens 6ES7142-3BH00-0XA0 is a sixteen-channel digital output module in the SIMATIC ET 200eco distributed I/O system. It receives PROFIBUS DP output data and switches 24 V DC field loads at up to 0.5 A per channel.

        Eight M12 sockets on 6ES7142-3BH00-0XA0 each carry two output channels. Pins 2 and 4 provide the paired output signals, pin 3 carries the 2M load-voltage ground and pin 5 provides protective earth, so the connector assignment links each channel pair to a common load-supply structure.

        The process outputs of 6ES7142-3BH00-0XA0 are not isolated from one another, while the PROFIBUS interface is isolated from the internal circuitry. A green LED follows every output and a red SF indicator reports a group fault; module diagnostics are readable over the bus, but the module does not generate process alarms.

        A completed 6ES7142-3BH00-0XA0 assembly uses the separately ordered ET 200eco connection block and provides IP65/IP67 protection. Total output loading is limited to 4 A up to +55 °C, and the module supports PROFIBUS transmission rates from 9.6 kbit/s through 12 Mbit/s.

        Technical notes
        Siemens 6ES7142-3BH00-0XA0 requires a separately ordered 6ES7194-3AA00-0.A0 connection block; use the complete 3BH00 suffix to distinguish this 16-output module from adjacent ET 200eco variants.

        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 are two output numbers printed around each M12 socket on 6ES7142-3BH00-0XA0?
        Each M12 socket on 6ES7142-3BH00-0XA0 carries two digital outputs: one on pin 2 and one on pin 4, so eight connectors provide all sixteen channels.
        What external part is still required when 6ES7142-3BH00-0XA0 is ordered alone?
        6ES7142-3BH00-0XA0 requires the matching ET 200eco connection block 6ES7194-3AA00-0.A0, which Siemens lists as a separate order item.
        How should total current be checked when several outputs on 6ES7142-3BH00-0XA0 are on together?
        Although each 6ES7142-3BH00-0XA0 channel is rated at 0.5 A, the combined module output current must not exceed 4 A at temperatures up to +55 °C.
        Does the SF LED on 6ES7142-3BH00-0XA0 identify the exact failed output?
        No. The red SF LED on 6ES7142-3BH00-0XA0 indicates a group fault; use the per-channel green LEDs and readable PROFIBUS diagnostics to narrow the problem.
        Are the sixteen output channels of 6ES7142-3BH00-0XA0 electrically isolated from each other?
        The outputs on 6ES7142-3BH00-0XA0 are not isolated from one another, although the PROFIBUS interface is isolated from the internal circuitry.
        Can 6ES7142-3BH00-0XA0 operate at 12 Mbit/s on PROFIBUS DP?
        Yes. 6ES7142-3BH00-0XA0 supports documented PROFIBUS DP rates through 12 Mbit/s; verify that the remaining station hardware and cable length also support the selected rate.
