440R Guardmaster Safety Relays

Allen-Bradley® Guardmaster® Safety Relays from Rockwell Automation check and monitor a safety system and either allow the machine to start or execute commands to stop the machine or control safety-related functions. Single-function safety relays are the most economical solution for smaller machines where a dedicated logic device is needed to complete the safety function. Modular and configurable safety relays are preferred where a large and diverse number of safeguarding devices and minimal zone control are required.
 
The Guardmaster EtherNet/IP™ Network Interface (440R-ENETR) allows Guardmaster Safety Relays with embedded optical bus technology to seamlessly communicate on an EtherNet/IP network. The information gathered from the GSR intelligent safety relays by way of the EtherNet/IP Interface helps minimize unplanned downtime and increase efficiencies for startup.
• Compliant with ODVA requirements for linear, star, and ring EtherNet/IP network topography
• Connects up to six Guardmaster safety relays on a single network interface
• Easy-to-use, compact solution

Guardmaster Safety Relays

DESCRIPTION SAFETY RELAYS SAFETY RELAYS EXPANSION RELAYS ACCESS CONTROL
Guardmaster DI/DIS
Consolidates functionality of two safety relays into a single electromechanical relay (DI) or solid state (DIS) outputs 		Guardmaster SI/CI
Ideal for safety functions using one dual or single channel safety device. Ideally suited for global E-stop function in combination with another GSR relay 		Guardmaster EM/EMD
Easily add 4 N.C. instantaneous (EM) or delayed (EMD) outputs to a system 		Guardmaster GLT/GLP
Developed for applications requiring access control monitoring the stop time, standstill or safe limited speed to unlock guards when equipment reaches a safe condition.

  • Two dual channel inputs
  • Rotary switch configures auto/manual or monitored manual reset and AND/OR logic of inputs
  • Universal inputs are compatible with interlocks, light curtains, safety mats, E-stops, and SensaGuard™
  • Single wire safety input and output to cascade safety relays and expand with output modules while maintaining SIL 3, PLe
  • Suitable for applications up to PLe, Cat. 4 per ISO 13849-1 and SIL CL3 per IEC 62061
  • Rotary switch configures auto/manual or monitored manual reset
  • Universal inputs are compatible with interlocks, light curtains, safety mats, E-stops, and SensaGuard
  • Single wire safety output connects to control other safety relays e.g. as Global E-Stop and expand with output modules while maintaining SIL 3, PLe
  • Suitable for applications up to PLe, Cat. 4 per ISO 13849-1 and SIL CL3 per IEC 62061
  • Four instantaneous or delayed safety outputs and one auxiliary PNP output
  • Controlled by single wire safety to expand outputs of a GSR module while maintaining SIL 3, PLe
  • Timer version provides on-delay, off-delay and jog outputs that can be configured via rotary switches
  • Designed to meet requirements of PLe, Cat. 4 per ISO 13849-1 and SIL CL3 per IEC 62061

  • Combinations of two instantaneous and two delayed switching outputs
GLP:
  • 2 PNP proximity sensor inputs for standstill or slow-speed monitoring to allow access when equipment reaches a safe speed
  • Supports standard proximity switches while maintaining a safety rating up to PLd per ISO 13849-1, SILcl 2 per IEC 61508
Configuration Rotary Switch
Housing 22.5 mm DIN rail mounted
Power Supply 24V DC
Safety Rating SILcl 3 per IEC62061
Certifications CE, cULus, C-Tick, CCC, S-Mark

The 440R family is designed to meet new functional safety standards, such as ISO 13849-1 or IEC 62061 and offers key functions to simplify installation and system complexity.
