Product information

Description

The Siemens SIRIUS ACT contact module is a robust and reliable component engineered for industrial control systems. Designed for seamless integration within the SIRIUS ACT series, this module provides two normally closed (NC) contacts, ensuring dependable switching performance in demanding automation environments. Its compact design and high-quality construction make it an essential element for modern control panels where precision and safety are paramount.

Advantages

This contact module offers exceptional durability and resistance to harsh industrial conditions, ensuring a long service life even in high-frequency switching applications. The use of secure screw terminals facilitates quick and reliable wiring, minimizing installation time and reducing the risk of loose connections. Its modular design allows for easy mounting and compatibility with a wide range of SIRIUS ACT actuators and indicators, providing flexibility for complex control system configurations.

Suitable for

  • Industrial automation control panels
  • Emergency stop circuits
  • Machine safety systems
  • Process control instrumentation
  • Switchgear and distribution boards

When it may not be suitable

This module is not intended for applications requiring normally open (NO) contacts or configurations needing more than two contact points per module. It is also not suitable for environments exceeding the specified electrical ratings or extreme conditions outside the standard industrial operating temperature range.

Key specifications

  • Contact configuration: 2 NC (Normally Closed)
  • Connection type: Screw terminals
  • Series: SIRIUS ACT
  • Mounting type: Front plate mounting

How to use

The contact module is designed for front plate mounting within a standard control panel enclosure. To install, align the module with the corresponding actuator or holder and snap it into place until it clicks securely. Connect the electrical wires to the screw terminals, ensuring that the conductors are properly stripped and tightened to the recommended torque to maintain a secure electrical connection. Always verify the wiring against your system schematic before applying power.

What to consider before purchase

  • Verify that your control system requires normally closed (NC) contacts.
  • Ensure the mounting space is compatible with the SIRIUS ACT modular system.
  • Check that the electrical load is within the rated specifications of the module.
  • Confirm that screw terminal connectivity meets your installation standards.

Usage recommendations

Always ensure that the power supply is disconnected before performing any installation or maintenance work on the contact module to prevent electrical hazards. Regularly inspect the screw terminals for tightness during routine maintenance cycles.
