3SU1401-2BF40-1AA0 Siemens SIRIUS ACT LED element

Contact modules

The contact modules are fitted with slow-action contacts (NO contacts or NC contacts). These ensure a high switching reliability even with small voltages and currents, such as 5 V/1 mA. They are suitable for use in electronic systems as well as conventional controls. The contact pieces of the NC contacts are positively driven.

Mounting system

• Front panel mounting:
  The contact modules are mounted on the rear face of a holder.
• Base mounting:
  The contact modules are used in the 3SU18 enclosures and are snapped into the lower part of the enclosure.

Connection methods

The contact modules are available with:

• Screw terminals
• Spring-loaded terminals
• Socket connection (THT) for PCB mounting

The terminal designations of the contact modules comply with EN 50013.

LED modules

The commanding and signaling devices can be illuminated via LED modules with integrated LEDs.

Mounting system

• Front panel mounting:
  The LED modules are mounted on the rear face of a holder in the center position.
• Base mounting:
  The LED modules are used in the 3SU18 enclosures and are snapped into the lower part of the enclosure.

Connection methods

The LED modules are available with:

• Screw terminals
• Spring-loaded terminals
• Socket connection (THT) for PCB mounting

The terminal designations of the LED modules comply with EN 50013.

LED test modules

The LED test modules are used to test the LED modules (AC/DC variants). One LED module is connected to each test module for testing.

AS-Interface modules

Pushbuttons and indicator lights of the SIRIUS ACT series can be connected to the AS-Interface communication system quickly, easily and reliably with the help of various solutions.

Using special modules, EMERGENCY STOP devices according to ISO 13850 can be directly connected through the standard AS-Interface with safety-related communication.

The following solutions are available:

• AS‑Interface modules
• AS‑Interface modules in safety-related version for EMERGENCY‑STOP mushroom pushbuttons according to ISO 13850

Electronic modules for IO‑Link

The SIRIUS ACT pushbuttons and indicator lights can be connected to IO‑Link quickly and safely. The connection is made via the electronic module for IO-Link.

Electronic modules for ID key-operated switches

The SIRIUS ACT ID key-operated switches can be used to set up authorization management systems for your machine/plant to identify persons.

The ID key-operated switch is fixed with the holder on the front panel and the electronic module is mounted on the back. The ID keys can be ordered as accessories. For the complete range, see .

The electronic modules for ID key-operated switches can be ordered with and without IO‑Link. The variant with IO‑Link can be easily programmed using function blocks.

Modules for PROFINET

Interface modules

Interface modules are used to establish communication between the controller and the SIRIUS ACT system. They feature an RJ45 socket, to which the PROFINET cable can be connected.

Thanks to the integrated PROFIsafe communication with fail-safe interface modules, an EMERGENCY STOP mushroom pushbutton, for example, can be integrated in a fail-safe manner, thus achieving a safety category up to SIL 3 (PL e).

When a defect develops on the interface module, it can be replaced without using a programming device thanks to the exchangeable memory module (supplied as standard with fail-safe interface module).

Terminal modules

With terminal modules, SIRIUS ACT commanding and signaling devices are simply connected to the interface module or other terminal modules using a 7-core flat ribbon cable, without the need for special tools. The terminal modules are mounted on the 3-fold holder of the SIRIUS ACT device series.

By combining terminal and interface modules, a SIRIUS ACT system with up to 21 devices can be set up.

For a complete overview of SIRIUS ACT with PROFINET, see .

Support terminals

The support terminals serve to collect electrical conductors, e.g. for all neutral conductors, in one enclosure. Up to four conductors, belonging to the same group, can be secured on one support terminal.

Mounting

• Front panel mounting:
  Support terminals for front plate mounting are installed on the rear face of a holder.
• Base mounting:
  The support terminals are used in 3SU18 enclosures and can be mounted at any placement position in the enclosure.

Connection methods

• Screw terminals
• Spring-loaded terminals

Electronic modules for ID key-operated switches

Advantages:

• Easy installation on the standard holder without special tools
• The status of operating modes can be queried via physical outputs or via the process image.
