Features:
- Sixteen 24 V DC digital inputs are grouped through eight double-assigned M12 field connectors.
- Electronic protection covers the sensor-supply outputs while reverse-polarity protection protects the module supply.
- PROFIBUS DP diagnostics and separate status indications expose channel activity and module faults.
Siemens 6ES7141-3BH00-0XA0 places binary input acquisition directly at an ET 200eco field station, reducing the transition between sensors and the distributed I/O node.
Its paired connector arrangement keeps two input channels at each M12 location without combining their individual signal states in the process image.
The module works with the separately ordered ET 200eco connection block, which completes the station-side power and PROFIBUS connection.
The Siemens 6ES7141-3BH00-0XA0 SIMATIC DP ET 200eco BM141 Digital Input Basic Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the sixteen inputs reach eight sockets
- First Channel Bank: Inputs 0 through 7 use pin 4 of M12 sockets X1 through X8.
- Second Channel Bank: Inputs 8 through 15 use pin 2 of the same eight sockets.
- Separate States: Each paired input retains its own process value and local indication.
- Shared Location: The dual assignment reduces connector count without merging the two signal circuits.
Connections available at each M12 position
- Sensor Feed: Pin 1 provides the 24 V DC sensor supply associated with the connector.
- Reference Potential: Pin 3 carries the sensor-supply ground reference.
- Protective Earth: Pin 5 is assigned to protective earth continuity.
- Two-Wire Devices: The input design accepts two-wire sensors within the stated quiescent-current limit.
Reading channel and module condition
- Input Indication: Green channel LEDs show the evaluated state of the individual digital inputs.
- Module Fault: The red SF indication separates a station or module fault from a normal channel state.
- Controller Access: Diagnostic records can be read across the PROFIBUS DP connection.
- Fault Isolation: The combination of local LEDs and bus diagnostics narrows checks to the module or affected input path.
Conditions that preserve the field-mounted design
- Supply Polarity: The module supply includes protection against reversed polarity.
- Sensor Faults: Electronic short-circuit protection acts on the sensor-supply outputs.
- Open Connections: Unused M12 positions require suitable sealing to maintain the enclosure rating.
- Station Interface: The specified ET 200eco connection block completes the power and network boundary.
