MSR Safety Relay to GSR Safety Relay Migration
Mitigate and Eliminate the Risks of Automation ObsolescenceRockwell Automation understands that safety relays are critical assets in your automation system. By migrating from your legacy CU3 and MSR300 to MSR, GSR, and CR30 safety relays, you can help lower costs, reduce wiring, and save panel space, while helping to ensure compliance to the latest regulations and environmental requirements.
The Guardmaster Safety Relay (GSR) next generation family of safety relay series are high-quality replacements for most of the Minotaur Safety Relay (MSR) family of safety relays.
In their consistent narrow design of 22.5 mm (0.88 in.) housing and equipped with configurable functions for reset and logic, the GSR relays can consolidate various functions of MSR with fewer models. Therefore, reducing stock requirements.
GSR offers configurable safety functions and consolidates safety circuits which result in fewer units, less space, and fewer costs. Due to the unique SWS cascading capability, logic combinations, and zones can be constructed quickly.
Why Upgrade or Migrate
While legacy Allen-Bradley Guardmaster CU3 and MSR300 safety relays have has a successful life, there are new replacement options that offer lower costs with an effective design that requires less wiring and panel space. Migration to these new safety relays can help ensure compliance to the latest regulations and environmental requirements, such as RoHS and WEEE.
Rockwell Automation announces that as of January 15, 2022, the CU3 and MSR300 safety relays will be discontinued and no longer available for sale.
New Product Overview
The new Allen-Bradley Guardmaster Safety Relays can monitor a broad range of devices in a variety of applications.
Equipped with the latest technology, the GSR family of safety relays offer configurable safety functions and consolidated safety circuits, resulting in fewer part numbers, less panel space, and lower cost.
- One or two (dual channel) inputs
- Single wire safety expansion
- Narrow package (smaller panel space)
- Configurable operation
- Cat 4 PLe and SIL3 rating on most models
- RoHS compliance
- Safety standards including ISO 13849-1 and IEC 62061
