At a Glance

Brand	Siemens
Model	6ES7131-4BD00-0AA0
Product Type	Digital input module
Core Function	Discrete input processing
Application	ET 200S distributed control stations

24 V DC input section

The module receives the supply through the station power module and processes four field signals.

Cable planning

Allow up to 1000 m with shielded wiring or 600 m with unshielded wiring.

Fixed standard response

Both signal transitions use the same 2–4.5 ms input-delay range, with a typical value of 3 ms.

Product Overview

6ES7131-4BD00-0AA0 provides four standard digital inputs for a SIMATIC ET 200S distributed I/O station.

The module combines a compact 15 mm housing with sensor-supply output and optional packed input addressing for grouped digital-module configurations.

Ordering focus: Retain the exact -4BD00-0AA0 article in the hardware selection, then match its standard input timing, cable limits and address-packing mode to the installed station.

Key Functions

Read remote discrete signals

Four DC input channels receive field states using IEC 61131 Type 1 input characteristics.

Plan long field cable runs

The cable limits distinguish shielded runs of up to 1000 m from unshielded runs of up to 600 m.

Integrate into the input image

The module occupies one byte without packing or four bits with packing, with green status indication at each channel.

Frequently Asked Questions

Can I run an unshielded 800 m sensor cable to 6ES7131-4BD00-0AA0?

No, unshielded cable is limited to 600 m, while shielded cable may extend to 1000 m.

Where does 6ES7131-4BD00-0AA0 obtain its 24 V operating supply?

The electronic module receives its rated 24 V DC supply from the ET 200S power module.

How much current should I reserve on the 3.3 V backplane for 6ES7131-4BD00-0AA0?

Allow a maximum backplane current consumption of 10 mA for the module.

Will a 12 V sensor output reliably register as on at 6ES7131-4BD00-0AA0?

No, the specified signal-1 range begins at +15 V and extends to +30 V.

Do the green LEDs on 6ES7131-4BD00-0AA0 provide a module diagnostic alarm?

The green LEDs show individual input states and the module does not provide a diagnostic function.

What addressing changes if I enable packing for 6ES7131-4BD00-0AA0?

The input allocation changes from one byte per module without packing to four bits with packing.

How large is 6ES7131-4BD00-0AA0 when planning spare-module storage?

The module body measures 15 mm wide, 81 mm high and 52 mm deep and weighs approximately 35 g.

Compatibility & Ordering Notes

Before ordering 6ES7131-4BD00-0AA0: Use the exact standard input module with a compatible ET 200S terminal base and power group, retaining its signal assignment and the configured input-image packing mode.

Compatibility Checklist for 6ES7131-4BD00-0AA0

• Match the exact -4BD00-0AA0 article and standard-input function.
• Supply the module through the appropriate 24 V DC station power group.
• Keep shielded and unshielded runs within their separate cable limits.
• Preserve the existing packed or unpacked input address assignment.
