Two new Allen-Bradley safety relays from Rockwell Automation deliver high-performance protection while helping OEMs reduce installation time and costs.
Offering broad application versatility and a modulareasily expandable designthe new MSR142RTP and MSR144RTP relays are the latest additions to the Allen-Bradley Guardmaster family of safety relays.
“Traditionallyusers have had to choose between safety and flexibility” says Kevin Zomchekproduct managerRockwell Automation. “These safety relays – with their modular design and reliable performance – put to rest this assumption.”
Featuring seven safety outputsfour auxiliary outputs and two solid-state auxiliary outputsthe MSR142RTP multi-output relay meets a variety of application requirementsincluding safety switcheslight curtains and safety mats. The MSR142RTP is housed in a 67.5mm-wide DIN-rail mount with removable terminals and accepts both solid-state and electromechanical inputs. It is also is equipped with automatic or monitored manual reset capabilities.
“The MSR142 helps users reduce installation costs and conserve cabinet space by allowing them to switch up to seven outputs without having to buy additional expansion modules” says Zomchek.
The second new relaythe MSR144RTPcan be connected in four different input wiring configurations and is easily expanded via a ribbon connector from the dedicated expansion modules. Up to five modules can be connected together in any combination of immediate or delayed-output modules. The relay allows users to switch several safety circuits or different voltages with one emergency stop command.
The MSR144RTP safety relaywhen combined with plug-in output expansion modulesis suitable for complex applications where flexibility and a high number of output contacts are required.
In addition to reducing installation costs and wiring complexitythe MSR144RTP helps to simplify inventoryas its modular design can be applied to meet a broad range of equipment specifications and application demands. With removable coded terminals and extended LED diagnosticsthe relay not only provides a high level of safetybut also helps to reduce service and maintenance costs.
