More Information

Overview Manuals Input Organization Sensor Wiring PROFIBUS Operation Indicators and Diagnostics

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).

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.
Description
Siemens 6ES7131-1BL12-0XB0 is a thirty-two-channel digital input electronic block for the SIMATIC ET 200L distributed-I/O system. It receives 24 V DC sensor states through a TB32L terminal block and transfers the input image through the station's PROFIBUS DP connection.

All thirty-two inputs on 6ES7131-1BL12-0XB0 share the electronic block without channel-to-channel isolation, while the input circuitry remains isolated from the PROFIBUS DP interface. Shielded and unshielded cable limits apply to the sensor run between the field device and the terminal block.

Bus-fault, input-state and 24 V indicators on 6ES7131-1BL12-0XB0 separate communication, channel and supply conditions at the station. Device diagnostics are available through PROFIBUS DP, but the block does not generate a separate diagnostic alarm.
