Guardmaster Guard Locking Safety Relay with Time Delay, Dual Channel

Ensure superior levels of protection for personnel and simplify installation and safety control system complexity with the Guardmaster Guard Locking Safety Relay with Time Delay by Rockwell Automation. The versatile GLT relay is designed for applications requiring access control monitoring the stop time, standstill or safe limited speed, to release machine guards when the machine is in a safe state. Access to the machine is only allowed when the maximum stop time has been reached. This unit features combinations of two instantaneous and two delayed switching outputs.

The Guardmaster relays are designed to meet new functional safety standards to help minimise downtime and keep your operations running smoothly. The single function units help to simplify purchasing and parts management as they can achieve many necessary safety system functions, making them a highly cost-effective solution.

Features and Benefits:

• Applicable for Stop Category 0 and 1
• Meets safety requirements of PLe, Cat. 4 per ISO 13849-1 and SIL CL3 per IEC 62061
• Features a TÜV approved rotary switch which configures the reset type and time delay
• Ease of installation and system flexibility due to single wire safety relay connection
• Terminals are grouped together by power inputs and outputs for clear connection
• DIN rail mounted - compact, space-saving and energy saving
• Offers easy installation due to consistent terminal layouts and configuration

What are Safety Relays?

Safety relays are devices which are used to monitor for errors or faults in a machine safety system, and can implement safety commands when they detect these errors to bring the risk down to an acceptable level. By doing this, they defend against hazards which could cause injury to personnel and damage to machinery. Single function relays manage one specific function, while multi-function relays can oversee different activities. Safety relays can also be connected to each other. They are often used in industrial environments such as factories, as part of a safety control circuit for dangerous machines. Typical applications include: safety mats, emergency stop push-buttons, light curtains, and magnetic switches. Rockwell Automation offer high-quality, reliable safety relays which give exceptional performance and ensure maximum protection and productivity.
