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.

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.
