The Siemens 6AV7674-1LA33-0AA0 SIMATIC Extension Unit 12" PROFIsafe is designed to expand operator-control functionality in compatible industrial HMI and IPC PRO installations. It mounts beneath a suitable 16:9 PRO device and provides six positions for configuring additional physical controls.
Unlike the hardwired and standard PROFINET variants, this model is designed for PROFIsafe communication, allowing supported I/O signals to be transmitted through a compatible PROFINET/PROFIsafe architecture. This makes it relevant to applications where operator-control expansion must be integrated into an appropriately designed safety-related automation system.
The control elements are ordered separately, allowing machine builders and system integrators to select suitable components for their operator stations. Before installation, verify device compatibility, safety-system requirements, network configuration, and the required control-element arrangement.

The Siemens 6AV7674-1LA33-0AA0 is intended for industrial operator stations requiring configurable physical controls and PROFIsafe communication. Correct selection depends on the main HMI or IPC PRO device, the required control elements, and the safety architecture of the automation system.
Applications
The Siemens 6AV7674-1LA33-0AA0 Extension Unit 12" PROFIsafe is an operator-control expansion unit designed for compatible fully enclosed SIMATIC HMI and industrial PC (IPC) PRO devices with a 16:9 format. It adds physical operator-control functions to an industrial workstation and supports the integration of compatible controls through PROFINET and PROFIsafe communication.
Typical applications include:
Industrial machine operation: Add operator-control devices to compatible HMI and IPC PRO installations.
Safety-related machine control: Integrate supported safety-related operator controls into a suitable PROFIsafe automation architecture.
Production and packaging lines: Expand operator stations with additional command and signaling functions.
Assembly systems: Provide additional physical controls for industrial workstations.
PLC-based automation: Connect supported control elements through compatible PROFINET/PROFIsafe systems.
Industrial operator stations: Combine visualization and physical control functions in a single installation.
Advantages
PROFIsafe communication: Supports the transmission of compatible I/O signals through PROFINET/PROFIsafe.
Six mounting positions: Allows flexible configuration with up to six compatible control elements.
12-inch system format: Designed for compatible fully enclosed 16:9 HMI/IPC PRO devices.
Safety-system integration: Supports appropriate safety-related control configurations when used with a compatible safety system.
Aluminum construction: Provides a robust enclosure and front structure.
Flexible operator interface: Allows the control arrangement to be adapted to machine requirements.
Modular installation: Extends compatible PRO operator stations without requiring a separate standalone control enclosure.
Technical FAQs
Q1: What is the Siemens 6AV7674-1LA33-0AA0 Expansion Unit?
It is the SIMATIC Extension Unit 12" PROFIsafe, an operator-control expansion unit designed for compatible Siemens HMI and IPC PRO devices.
Q2: What is the main function of this Extension Unit?
It expands an industrial operator station by providing mounting positions for physical control and signaling devices, with supported I/O signals transmitted through PROFINET/PROFIsafe.
Q3: How many control elements can be installed?
The unit provides six mounting positions and supports installation of up to six compatible control elements. The control elements must be ordered separately.
Q4: What is the difference between PROFIsafe and standard PROFINET?
PROFINET provides industrial Ethernet communication, while PROFIsafe adds a safety communication layer for supported safety-related applications. A compatible safety controller and properly configured system are required.
