Features:
- Thirty-two 24 V DC digital inputs
- TB32L terminal-block connection
- PROFIBUS DP diagnostics with channel and bus indication
Within a SIMATIC ET 200L station, Siemens
6ES7131-1BL12-0XB0 collects thirty-two field input states for transfer to the PROFIBUS DP master.
The TB32L terminal block carries sensor wiring into the electronic block, where input circuits share a common internal potential group.
Green channel LEDs show individual input states, while separate indicators distinguish 24 V supply presence from a PROFIBUS bus fault.
The Siemens 6ES7131-1BL12-0XB0 ET 200L Digital Input Electronic Block may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Channel Structure
- Input count: The electronic block accepts thirty-two digital field signals.
- Rated signal: Each channel evaluates a 24 V DC input circuit.
- Channel isolation: Inputs are not electrically isolated from one another.
- Bus isolation: The input electronics are isolated from the PROFIBUS DP interface.
Terminal and Cable Limits
- Terminal block: A TB32L provides the field connection for the thirty-two inputs.
- Shielded cable: Sensor runs may extend to 1,000 m with shielding.
- Unshielded cable: The maximum documented length is 600 m.
- Two-wire sensors: The permitted quiescent current is 1.5 mA maximum.
Distributed-I/O Exchange
- Bus connection: The ET 200L station transfers the input image through PROFIBUS DP.
- Bus rate: Communication operates at up to 1.5 Mbit/s.
- SYNC: The station supports the PROFIBUS SYNC control command.
- FREEZE: Input values can be captured through the PROFIBUS FREEZE function.
Local Status Display
- Input LEDs: Green indicators show the state of individual digital inputs.
- Bus-fault LED: A red BF indicator identifies a PROFIBUS communication fault.
- Supply LED: A green 24 V indicator shows load-group power.
- Diagnostic path: Module diagnostics are available through PROFIBUS DP without a separate diagnostic alarm.
