At a Glance

Brand	Siemens
Model	6ES7131-1BH01-0XB0
Product Type	Digital input electronics block
Core Function	Acquire binary sensor signals
Application	PROFIBUS DP distributed I/O

Binary field sensing

Sixteen 24 V DC inputs read switches and compatible proximity sensors.

PROFIBUS station link

The integrated DP interface exchanges the input data with the master.

Visible station diagnostics

Channel LEDs, a BF bus-fault LED and an ON supply LED support service checks.

Product Overview

6ES7131-1BH01-0XB0 is an ET 200L digital input electronics block with 16 channels arranged in two groups of eight. It connects field switches and proximity sensors to a PROFIBUS DP master through a compact distributed I/O station.

The electronics block provides local input-state indication and PROFIBUS diagnostics, with galvanic isolation between the field channels and the bus interface; channels within the block are not isolated from each other.

Ordering focus: Pair the electronics block with the correct ET 200L terminal block and use the device master file and bus speed required by the installed DP master.

Key Functions

Read switches and proximity sensors

The 24 V DC input characteristic supports mechanical switches and compatible two-wire proximity sensors within the permitted off-state current.

Exchange process inputs over PROFIBUS DP

The integrated slave interface supports data rates up to 1.5 Mbaud and FREEZE operation.

Locate station and bus conditions

Green channel LEDs indicate the input signals, while the red BF and green ON LEDs show bus and electronics-supply conditions.

Frequently Asked Questions

Can I connect two-wire proximity sensors to 6ES7131-1BH01-0XB0?

Yes, compatible two-wire proximity sensors can be connected when their closed-circuit current does not exceed 1.5 mA.

Does 6ES7131-1BH01-0XB0 support PROFIBUS station link for mobile equipment?

A voltage from 13 to 30 V is recognized as an ON signal.

Can the DP master freeze the input image of 6ES7131-1BH01-0XB0?

Yes, the electronics block supports PROFIBUS DP FREEZE operation.

What must I change to run 6ES7131-1BH01-0XB0 at 45.45 kbaud?

Use an updated device master file or STEP 7 V4.02 with K4.02.6 or later support for that transmission rate.

Does 6ES7131-1BH01-0XB0 isolate each input from the next one?

No, the channels are isolated from PROFIBUS DP but are not isolated from one another.

Which local indicators should I check when 6ES7131-1BH01-0XB0 stops exchanging data?

Check the red BF LED for a bus fault and the green ON LED for the electronics supply.

How should I protect the sensor-supply terminals of 6ES7131-1BH01-0XB0?

The 1L+, 2L+ and 3L+ sensor-supply terminals may be protected with a maximum 6 A circuit breaker with B or C characteristic.

Compatibility & Ordering Notes

Before ordering 6ES7131-1BH01-0XB0: Select the terminal-block arrangement for the ET 200L electronics and sensor wiring, then match the PROFIBUS address, transmission rate and device master file to the installation.

Compatibility Checklist for 6ES7131-1BH01-0XB0

• Use the ET 200L terminal block required by the station connection arrangement.
• Keep the two-wire sensor off-state current within the 1.5 mA limit.
• Use the updated device description when selecting 45.45 kbaud.
• Apply the permitted circuit-breaker rating to the sensor-supply groups.
