At a Glance

Brand	Siemens
Model	6ES7145-4GF00-0AB0
Product Type	Analog output module
Core Function	Four current outputs for actuator control
Compatible Series	SIMATIC ET 200pro

Current Ranges

Select ±20 mA, 0–20 mA or 4–20 mA output ranges.

Channel Diagnostics

Provides per-channel wire-break diagnostics outside the zero range.

Separate Connection Module

The IO connection module is ordered separately from the electronic module.

Product Overview

6ES7145-4GF00-0AB0 is a four-channel current-output electronic module for SIMATIC ET 200pro distributed I/O. Its High Feature design supports three selectable current ranges and channel diagnostics.

The module includes its bus module and requires a separately ordered 6ES7194-4..00-0AA0 IO connection module. It provides configurable substitute values and a parameterizable diagnostic alarm.

Ordering focus: match the 4GF00 current-output variant and order the appropriate IO connection module for the station.

Key Functions

Actuator Current Control

Drives four analog current outputs in ±20 mA, 0–20 mA or 4–20 mA range.

Wire-Break Detection

Reports a wire break by channel when the output is not set to a zero range.

Substitute-Value Operation

Allows substitute output values to be configured for the application.

Can 6ES7145-4GF00-0AB0 detect an open output wire?

The unit provides per-channel wire-break diagnostics outside the zero range.

How much load resistance can 6ES7145-4GF00-0AB0 drive?

Each current output supports a load resistance of up to 600 Ω within its rated range.

What shielded cable length is allowed for 6ES7145-4GF00-0AB0?

The maximum shielded cable length is 30 m.

Can I configure fallback values for 6ES7145-4GF00-0AB0?

The module allows substitute output values to be configured.

How quickly does 6ES7145-4GF00-0AB0 update all channels?

The maximum cycle time across all four channels is 3 ms.

Compatibility & Ordering Notes

Before ordering 6ES7145-4GF00-0AB0: verify the ET 200pro station layout, output range and separately ordered IO connection module.

ET 200pro selection checklist

• Use the current-output 4GF00 variant rather than the 4FF00 voltage-output variant.
• Select the current range and output wiring for each actuator.
• Allow for the specified load resistance and shielded cable length.
