More Information

Overview Manuals Signal Thresholds Sensor Feed Address Packing Status Display

Features:

  • Each 15 mm ET 200S module acquires two IEC 61131 Type 1 digital inputs at 24 V DC.
  • Packed or unpacked addressing represents the two channels as two bits or one byte.
  • Green channel LEDs provide local state indication without a module-level diagnostic function.
Siemens 6ES7131-4BB01-0AA0 groups five identical two-channel input modules under one order number.

The input path supports switch contacts and two-wire sensors while enforcing defined voltage and residual-current limits.

A fixed input delay and selectable address packing determine how the two field states appear in the ET 200S station.

All prices are shown in USD.

6ES7131-4BB01-0AA0 Input-State Limits

  • Signal zero: The input interprets -30 to +5 V as the low state.
  • Signal one: The active-state range is 15 to 30 V.
  • Rated circuit: Both channels use the 24 V DC input design.
  • Input standard: IEC 61131 Type 1 behavior applies to each channel.

6ES7131-4BB01-0AA0 Two-Wire Connection

  • Sensor type: Two-wire field sensors can be connected.
  • Residual current: Quiescent current is limited to 1.5 mA.
  • Supply output: The sensor-supply output is rated at 500 mA.
  • Power source: Field power enters through the associated ET 200S power module.

6ES7131-4BB01-0AA0 Process-Image Allocation

  • Packed format: The two inputs can occupy two process-image bits.
  • Unpacked format: The alternative representation occupies one byte.
  • Physical channels: Address packing does not change the two input circuits.
  • Configuration point: The address format is selected in the ET 200S station setup.

6ES7131-4BB01-0AA0 Local Indication

  • Channel LEDs: Each digital input has a green state indicator.
  • Displayed state: The two LEDs follow the acquired input values.
  • Diagnostic limit: The module does not generate its own diagnostic functions.
  • Troubleshooting role: Local indication must be combined with field-voltage and station-status checks.
Description
Supplied as a pack of five, Siemens 6ES7131-4BB01-0AA0 is a SIMATIC DP ET 200S electronic module with two standard 24 V DC digital inputs in a 15 mm format. Each module receives field power from the associated power module and transfers two input states through the ET 200S backplane.

The two channels on 6ES7131-4BB01-0AA0 follow IEC 61131 Type 1 input behavior. Each field signal is evaluated against defined signal-zero and signal-one bands, while two-wire sensors are accepted within the specified quiescent-current limit.

Address allocation for 6ES7131-4BB01-0AA0 can use two packed bits or one unpacked byte. The physical channels remain unchanged, and their input delay is fixed with a typical response of 3 ms.

Green channel LEDs on 6ES7131-4BB01-0AA0 show the two input states. The module has no internal diagnostic function, and the channels share their field-side reference while remaining isolated from the backplane bus.

Technical notes
Siemens 6ES7131-4BB01-0AA0 uses a fixed input delay and provides no module diagnostics. Keep a two-wire sensor's quiescent current within the documented 1.5 mA limit.

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.
Why does an input LED remain off even though a sensor is wired to 6ES7131-4BB01-0AA0?
Measure the field signal at Siemens 6ES7131-4BB01-0AA0 and confirm it reaches the 15 to 30 V signal-one band, then check the 24 V field supply and sensor connection.
Why can a two-wire sensor create a false ON state on Siemens 6ES7131-4BB01-0AA0?
The sensor residual current must remain at or below the 1.5 mA quiescent-current limit of 6ES7131-4BB01-0AA0; a higher off-state current can prevent a valid signal-zero condition.
Why are the two input states mapped to the wrong PLC addresses after replacing 6ES7131-4BB01-0AA0?
Check whether Siemens 6ES7131-4BB01-0AA0 is configured for two packed bits or one unpacked byte and match the replacement station address layout to the existing project.
Why is no diagnostic alarm generated when a field circuit connected to 6ES7131-4BB01-0AA0 fails?
Siemens 6ES7131-4BB01-0AA0 has no module diagnostic function. Use its green channel LEDs together with field-voltage measurements and the ET 200S station status.
How can receiving staff confirm that 6ES7131-4BB01-0AA0 is the correct packaged item?
Verify the complete Siemens 6ES7131-4BB01-0AA0 order number and the five-piece pack description; each included unit must be a 15 mm ET 200S 2 DI Standard module.
