Features:
- Reads sixteen 24 V DC P-switching field signals with the IEC 61131 Type 3 characteristic.
- Applies a selectable 0.05 to 20 ms input delay before transferring channel states to the controller.
- Separates sixteen channel LEDs from module-level DIAG and PWR indication on a BU type A0.
Siemens 6ES7131-6BH01-0BA0 forms the sixteen-channel digital input layer of a SIMATIC ET 200SP station.
Field voltage thresholds determine the binary state, and the selected filter delay controls when that state enters the process image.
Two input bytes carry channel data while two quality-information bytes and front LEDs provide separate status references.
The Siemens 6ES7131-6BH01-0BA0 DI 16x24VDC ST Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Sixteen-channel input path
- Field state: Each terminal receives a 24 V DC P-reading input.
- Threshold decision: IEC 61131 Type 3 limits determine whether the incoming voltage is read as 0 or 1.
- Process image: Sixteen channel states occupy two controller input bytes.
- Quality data: Two additional bytes report the module quality information.
Parameterizable input timing
- Fastest setting: A channel delay can be set to 0.05 ms.
- Longest setting: The selectable upper delay is 20 ms.
- Transition coverage: The selected delay applies to both 0-to-1 and 1-to-0 transitions.
- Line contribution: The documented response also includes 30 to 500 microseconds depending on cable length.
Status and fault reporting
- Channel state: Sixteen green LEDs correspond to the sixteen digital inputs.
- Module state: The green/red DIAG LED identifies module-level diagnostic status.
- Power state: A green PWR LED reports monitored supply voltage.
- Wire break: Optional module-wise wire-break diagnostics apply with the documented protective circuit.
A0 terminal organization
- BaseUnit type: The module installs on BU type A0.
- One-wire connection: One-wire sensors connect directly through the A0 BaseUnit arrangement.
- Multiwire connection: Two-, three- and four-wire variants use the A0 BaseUnit with the required potential distributor.
- Mechanical coding: Type A coding prevents confusion with incompatible ET 200SP terminal assignments.
