Delivery release Extension Units Hardwired (19" and 22") and operator controls for the SIMATIC HMI PRO devices

  • Entry
  • Associated product(s)
The portfolio of the HMI devices with all-round IP65 protection is being expanded by the Extension Units Hardwired (19" and 22") and the operator controls. These components enable easy adaptation to individual customer requirements for machine-level operator control and monitoring, and are available effective immediately.

The system components for PRO devices are only suitable for SIMATIC HMI/IPC PRO devices. This includes the expansion elements, such as the extension units and their operator controls. All these components in combination with basic units from the SIMATIC IFP PRO and SIMATIC IPC477 PRO range enable users to create their customized system based on standardized products: An attractive solution for visualization and automation without the need for control cabinets.

Extensions Units:





Example for installation of an extension unit with operator controls

The new extension units for the 16:9 PRO devices are suitable for flexible installation of various operator controls that easily and individually expand the local operating options. They are designed to match the PRO devices and can be easily mounted below them by the customer.

The extension units are characterized by:

  • Availability in four different sizes for the 12", 15",19" and 22" PRO devices, respectively.

  • Three connection options per size: Hardwired, PROFINET and PROFISAFE.

  • Large selection of operator controls.

  • Complete flexibility in arranging the operator controls.

  • Fast wiring using pre-assembled wiring harness and connectors.

Thanks to these properties, the extension units enable a wide variety of operating scenarios for customers.

Only the Extension Units Hardwired for the respective 19" and 22" PRO devices are released in this initial stage of delivery. The operator controls in the Hardwired version are connected using two field terminals that can be easily and quickly plugged and pulled. As a result, they can be easily wired to the automation system.




Each extension unit offers a specific number of slots for operator controls:

  • Extension Unit 19": 10 slots

  • Extension Unit 22": 12 slots

A maximum of 8 standard operator controls + 2 emergency stop buttons (two safety inputs) may only be used (connected) with the Hardwired version of the extension units. Certain rules must be observed. The emergency stop may be installed as required (please refer to manual).

The assembling of the Extension Units is very simple. The individual operator controls can be easily mounted and quickly wired in the pre-punched positions without special tools. Just as easily, elements can later be replaced or newly installed in the event of a defect or during a machine retrofit or expansion.
The assembling of the extension units is performed by the customer.


The assembling of the extension units is performed on site.

In summary, the extension units can be freely configured and upgraded, are easy to customize, and provide maximum flexibility. This means you can easily develop and implement standardization concepts for your machine or plant.

Operator controls for the extension units:

The released operator controls for the extension units offer easy and straightforward assembling of a customized system solution with standard components. The type, number and arrangement of the operator controls in the extension units can be individually defined and according to customer request. In addition, these components can be upgraded or exchanged (even at a later date) thanks to the properties of the extension units.

The operator controls are made of high grade plastics with IP65 degree of protection, ideally suited for high-end industrial applications. They are also characterized by the modern and compact design.

The following operator controls are available:

  • Emergency stop

  • Selector switch

  • Illuminated pushbutton

  • Keyswitch

  • Indicator lights


An operator control is supplied in a kit that contains the following parts:

  • Operator control with threaded ring

  • Electronic connection module

  • Required fasteners

  • Lens assemblies depending on type (for illuminated pushbuttons and indicator lights)

With the illuminated pushbuttons and indicator lights, color-coded commands are differentiated by the various lens assemblies. If the concepts are changed during the life cycle of the plant, the color of the operator controls can be easily changed at any time by exchanging the lens assemblies.




Lens assemblies (5x) for illuminated pushbuttons and indicator lights

The operator controls are connected by means of the connection module connector and the wiring harness plug (pre-assembled in the extension unit)
