At a Glance

Brand	Siemens
Model	6ES7131-4BB00-0AB0
Product Type	Digital input electronics
Core Function	Acquiring switch and proximity-sensor states
Application	ET 200S modular input stations

Configurable input response

Four nominal delay selections range from 0.1 to 15 ms for both input transitions.

Sensor power on the base

The module provides a rated 500 mA sensor supply with electronic short-circuit protection.

Channel and group indication

Green channel LEDs indicate input states, while a red SF LED identifies a group error.

Product Overview

6ES7131-4BB00-0AB0 acquires two 24 V DC input signals from switches and compatible proximity sensors in an ET 200S station.

The High Feature electronics combine selectable input delay and process interrupts with clock-synchronized operation, and the installed terminal-base version determines the field-sensor, ground and AUX1 connections.

Ordering focus: Keep the 0AB0 High Feature version, preserve the exact terminal-base wiring and match the configured input delay and interrupt behavior to the installed application.

Key Functions

Adapt input filtering to the field signal

Nominal delays of 0.1, 0.5, 3 and 15 ms can be configured for rising and falling signal transitions.

Acquire input events with station timing

Configurable process interrupts and clock-synchronized operation support applications that require coordinated input acquisition.

Supply and monitor connected sensors

The module supplies the sensor circuit through an electronically protected output and provides channel-state indication together with readable diagnostic data.

Frequently Asked Questions

How do I connect three-wire sensors through a TM-E15S24-01 base for 6ES7131-4BB00-0AB0?

Connect channel 0 signal, sensor supply and ground to terminals 1, 2 and 3, and connect the corresponding channel 1 wires to terminals 5, 6 and 7.

May an unused 48 V wire be landed at terminal 4 or 8 of a TM-E15S24-01 base carrying 6ES7131-4BB00-0AB0?

No, those unused-wire positions are limited to circuits up to 30 V DC.

Which input-filter delay settings can I select for 6ES7131-4BB00-0AB0?

The configurable nominal delay settings are 0.1, 0.5, 3 and 15 ms for both rising and falling transitions.

Will a sensor output of 10 V be guaranteed to register as ON on 6ES7131-4BB00-0AB0?

No, the specified ON-state input-voltage range starts at 11 V.

Can I run an 800 m unshielded sensor cable to 6ES7131-4BB00-0AB0?

No, unshielded signal cable is limited to 600 m, while shielded cable is permitted up to 1,000 m.

How can I distinguish an active input from a group fault on 6ES7131-4BB00-0AB0?

A green LED indicates each channel’s input state, while the red SF LED indicates a group error.

Is short-circuit protection on the sensor supply of 6ES7131-4BB00-0AB0 independent for each channel?

No, the electronic sensor-supply short-circuit protection acts per module.

Compatibility & Ordering Notes

Before ordering 6ES7131-4BB00-0AB0: Retain the two-channel High Feature order number, the existing base-specific sensor and AUX1 wiring, and the configured filter, interrupt and synchronization settings when replacing the electronics.

Compatibility Checklist for 6ES7131-4BB00-0AB0

• Use the exact terminal diagram for the installed TM-E15 base.
• Keep the 24 V DC supply and sensor load within the 500 mA rating.
• Preserve the application’s configured delay and process interrupts.
• Check the sensor’s OFF-state leakage against the 1.5 mA limit.
