Allen Bradley Guardmaster 440N Safety Relay, 1 NO Safety Contacts, 1

Experience exceptional protection and improve the security of your machine guard with the 440N-S32013 Sipha Control Unit 1 by Allen Bradley Guardmaster. This controller is designed to be used with the Sipha Non-Contact Safety Switches and provides monitoring and control of the sensors. This unit helps to reduce downtime and ensure that your machine processes run smoothly and efficiently.

The 440N-S32013 Sipha Control Unit 1 has 24 V ac/dc supply voltage, 1NO Safety Contact, 1NC Solid State Auxiliary Contact. It is 35mm DIN rail mountable, ensuring easy and fast installation. It has an operating temperature of -10 to +55° (+14…+131°). The housing is 22.5mm and the case is comprised of durable polycarbonate. It also has automatic reset.

This controller can provide a high-integrity system for high-risk applications when used with a single sensor. For other applications multiple sensors and mechanical switches can be connected to one Sipha control unit. It has facilities which allow you to connect a manual reset button and monitor external devices, such as contactors.

The Sipha Safety Switches feature magnetically sensitive elements which must be activated in a specific sequence to operate correctly, ensuring greater reliability and security for complex applications. They cannot be defeated by a simple magnet. These dependable switches are perfectly suited for use with sliding, hinge, and lift-off safety guards. When the safety barrier is released the power is isolated, preventing dangerous machinery from running while personnel can access it and reducing risk of injury.

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.

Non-contact safety switches are low-maintenance and endure less wear-and-tear. They are also resistant to shocks and vibrations, and they cannot be easily tampered with or manipulated. This makes them highly durable and reliable. They are a cost-effective, ideal safety solution for machine guard doors and gates, allowing you to restrict access to hazardous areas where machinery may be in motion. For this reason they are often used in industrial environments.
