Features:
- Sixteen 24VDC inputs collect discrete field states for the ET 200L-SC station.
- Smart Connect expansion accepts as many as sixteen additional digital or analog channels.
- Channel, bus-fault and supply indicators separate field activity from station-level conditions.
The signal thresholds of 6ES7131-1BH12-0XB0 distinguish low and high field states before the corresponding input status is transferred through PROFIBUS DP.
Three load-voltage paths organize the field supply for 6ES7131-1BH12-0XB0, and each path has its own no-load current boundary.
Input channels on 6ES7131-1BH12-0XB0 are not isolated from one another, but the complete input side is separated from the PROFIBUS DP interface.
The Siemens 6ES7131-1BH12-0XB0 SIMATIC ET 200L-SC Digital Input Electronic Block may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How field power and input states are organized
- Load paths: L1+, L2+ and L3+ form the three documented load-voltage groups of 6ES7131-1BH12-0XB0.
- Shared potential: The sixteen input channels are not electrically isolated from one another.
- Bus separation: The input side is electrically separated from PROFIBUS DP.
- Sensor connection: Two-wire sensors are supported when their quiescent current remains within the input limit.
Extending the ET 200L-SC station from the electronic block
- Base channels: 6ES7131-1BH12-0XB0 supplies sixteen digital input channels in the electronic block.
- Expansion type: The Smart Connect path accepts digital or analog extension channels.
- Expansion limit: A maximum of sixteen additional channels can be attached through the documented Smart Connect arrangement.
- Terminal interface: The electronic block works with the specified TB 16L terminal-block connection while the product definition identifies TB 16SC for Smart Connect expansion.
Separating field-state information from bus and supply conditions
- Channel state: Green input indicators on 6ES7131-1BH12-0XB0 show the state of individual digital inputs.
- Bus fault: The red BF indicator identifies a PROFIBUS DP fault condition.
- Supply presence: A green indicator monitors the incoming 24V supply.
- Diagnostic boundary: Diagnostic information is available even though the module does not generate process alarms.
Applying the documented signal and cable boundaries
- Low state: 6ES7131-1BH12-0XB0 interprets an input from -30V through +5V as signal 0.
- High state: An input from 13V through 30V is interpreted as signal 1.
- Shielded run: Shielded field wiring is permitted up to the longer documented cable limit.
- Unshielded run: The unshielded cable limit is shorter and must be applied separately from the shielded value.
