Product Overview
The Siemens 6ES7132-4FB01-0AB0 is a SIMATIC ET 200S digital output electronic module designed for controlling AC-operated loads in distributed automation systems. It provides two digital output channels and supports load voltages from 24 V AC to 230 V AC, making it suitable for switching compatible industrial actuators and electrical equipment.
Unlike the 24 V DC output modules in the same ET 200S product family, this module is specifically intended for AC output applications. It receives output commands from the controller through the ET 200S backplane bus and switches the connected loads according to the configured PLC logic.
Each output channel supports a rated current of 2 A. The module includes electrical isolation between the output circuits and the backplane bus, helping separate the field-side load circuit from the internal communication system.
The 6ES7132-4FB01-0AB0 is suitable for distributed control installations where AC switching is required at the field level. Before replacement or system expansion, engineers should verify the load voltage, output current, frequency, and electrical characteristics of the connected devices.

Working Principle
The 6ES7132-4FB01-0AB0 operates by converting digital control commands from the PLC into switching actions for connected AC loads.
The basic signal path is:
PLC Controller → ET 200S Backplane Bus → 6ES7132-4FB01-0AB0 → AC Load
When the PLC program activates an output channel, the module switches the corresponding AC load circuit. When the control command is removed, the output returns to its inactive state according to the module’s switching characteristics.
Each channel supports a rated current of 2 A. However, the total current of both outputs is limited to 2 A per module at temperatures up to 40°C and 1 A at temperatures up to 60°C. These limits must be considered when multiple loads operate simultaneously.
The module supports AC load voltages from 24 V to 230 V, with an operating frequency of 47 Hz to 63 Hz. Output switching delay for resistive loads is specified at a maximum of 15 ms for both switching transitions.
Electrical isolation between the output circuits and the backplane bus helps prevent direct electrical interaction between the field-side load circuit and the internal system bus.
Role in the SIMATIC ET 200S Control Architecture
The 6ES7132-4FB01-0AB0 functions as the AC digital output interface in a Siemens SIMATIC ET 200S distributed I/O station.
The CPU executes the control program and sends output data through the distributed I/O communication system. The ET 200S interface transfers the corresponding data to the electronic module, which switches the connected AC loads.
A typical control arrangement is:
SIMATIC PLC → ET 200S Interface → Backplane Bus → 6ES7132-4FB01-0AB0 → AC Field Devices
| System Component | Function |
|---|---|
| SIMATIC PLC | Executes the automation program and generates output commands |
| ET 200S Interface Module | Connects the distributed I/O station to the control network |
| ET 200S Power Module | Supplies the required electrical power to the station |
| ET 200S Terminal Module | Provides electrical connections for the electronic module |
| 6ES7132-4FB01-0AB0 | Switches two AC digital output channels |
| Field Wiring | Connects the output channels to external loads |
| AC Actuators | Perform switching or operating functions according to PLC commands |
The output module handles the field-side switching function, while the controller and distributed I/O interface manage the control data exchange.

Technical FAQs
Can the 6ES7132-4FB01-0AB0 control 24 V DC loads?
No. This module is specifically designed for AC digital output applications. It supports rated load voltages from 24 V AC to 230 V AC. A compatible DC output module should be selected for 24 V DC loads.
How many output channels are available on this module?
The module provides two digital output channels. Each channel has a rated output current of 2 A, subject to the module’s total current limitations and operating temperature.
Does the 6ES7132-4FB01-0AB0 support channel diagnostics?
No. The technical specification for this particular module does not include a diagnostics function. Its green LEDs provide individual channel status indication.
What should be considered when operating both outputs simultaneously?
The total current must remain within the module’s specified limit. The maximum combined output current is 2 A per module at temperatures up to 40°C and 1 A at temperatures up to 60°C. The connected loads must be evaluated accordingly.
