Technical specifications
Input characteristics, BaseUnit requirements and configuration details for the DI 8x24VDC ST.
Eight standard digital inputs
Use this module to acquire 24 V DC signals from switches and PNP sensors in an ET 200SP station. It provides standard digital inputs, not counter, oversampling or fail-safe functions.

Choose filtering for the signal
Short input delays suit fast-changing signals; longer delays suppress short disturbances. The factory parameter setting is 3.2 ms. A signal change is detected only after it persists for the configured delay.
Select the BaseUnit for the sensor connection
| Parameter / condition | Connection | BaseUnit arrangement |
|---|---|---|
| 1-wire | 1-wire | BU type A0 |
| 2-wire | 2-wire | BU type A0 |
| 3-wire | 3-wire | BU type A0 with AUX terminals, or a potential distributor module |
| 4-wire | 4-wire | BU type A0 plus a potential distributor module |
Build the potential group correctly
A light-colored BaseUnit starts a new potential group and supplies its voltage buses. Dark-colored BaseUnits continue the potential group from the module on the left. Set the module’s potential-group parameter to match the BaseUnit arrangement.

Supply and sensor power
- Supply voltage L+
24 V DC
Permissible range: 19.2–28.8 V DC
- Reverse polarity protection
Yes
- Module current consumption
50 mA
Maximum; all channels supplied from the sensor supply
- Sensor supply outputs

- Sensor supply voltage
19.2 V
Minimum
- Sensor supply current limit
700 mA
Maximum per channel and per module; not 700 mA × 8
- Sensor supply short-circuit protection
Yes
Module-level protection
- Power loss
1 W
Typical at 24 V with all 8 inputs supplied through the sensor supply
- Channel-to-channel isolation
No
- Isolation from backplane bus
Yes
Diagnostics and indication
- Configurable module diagnostics
Missing supply voltage, sensor-supply short circuit and wire break
- Supply indicator
Green PWR LED
- Input status indicators
Green channel LEDs
- Module diagnostic indicator
Green/red DIAG LED
- Dedicated channel diagnostic LEDs
No
Wire-break diagnostics with mechanical contacts
With wire-break detection enabled, connect a 25–45 kΩ resistor in parallel with each mechanical contact so a small monitoring current can flow when the contact is open. No parallel resistor is required when wire-break detection is disabled. The module reports wire-break diagnostics at module level.

Parameter scope depends on the configuration path
STEP 7 allows channel-specific input-delay settings. With a PROFIBUS GSD configuration, input delay is module-wide; the manual describes data record 128 for the restricted parameterization options. Select the configuration path before assigning channel filtering.

Order the one-piece module, not the ten-piece pack
6ES7131-6BF01-0BA0 is the one-piece order number. The module manual also lists 6ES7131-6BF01-2BA0 as a ten-piece packing unit. Select a type A0 BaseUnit separately for the intended sensor wiring; this order number identifies the electronic input module.
