Allen Bradley Guardmaster, GSR 440R / Guardmaster SI Safety Relay, 24V dc, Dual-Channel, 2 Safety Contacts

Rockwell Automation Guardmaster 440R SI/CI - Single Input Safety Relays

Ensure easier installation and a simplified yet high-performance safety control system with the 440R SI/CI Guardmaster Safety Relays by Rockwell Automation. These relays are perfectly suited for simple safety functions using one dual or single channel safety device, and for global E-stop function in combination with another GSR relay.

With the Guardmaster family of safety relays, many important components in a control system such as safety interlock switches, pressure sensitive safety mats, emergency stop devices, and OSSD devices such as safety light curtains are compatible with the same relay without added configuration, saving you time and money. These 440R SI/CI Safety Relays help you to minimise downtime through reliable, fast fault detection which prevents risk of damage to machinery and protects personnel from injury.

Features and Benefits:

• Compact solution which saves energy and space on DIN rail
• TÜV-approved single rotary switch configures auto/manual or monitored manual reset
• Universal inputs are fully 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, PL
• Suitable for applications up to PLe, Cat. 4 per ISO 13849-1 and SIL CL3 per IEC 62061
• Terminals are grouped together for power, inputs and outputs for clear connection

Note:

Terminals on the CI model are arranged in a similar layout to legacy Guardmaster MSR safety relays.
