ROCKWELL Automation has released important new additions to its line of Allen-Bradley Guardmaster Minotaur safety relays, offering greater safety monitoring functionality at lower cost.
In addition to the MSR21L and MSR22LM for light curtains, and the MSR23M for safety mats, new delayed output, two-hand control, and expansion models are available.
The family also offers Category 4 rating, and electronic fuses with removable terminals and solid state outputs on selected models.
The introduction of the MSR200 family of modular expandable relays adds a whole new dimension to the Allen-Bradley Guardmaster safety relay offering.
Using plug-and-play expansion modules, the MSR200 can provide up to 22 input circuits from various types of safety devices -- such as light curtains, safety mats, interlock switches and e-stops -- plus up to 10 output circuits, while reducing wiring and panel space.
The MSR200 microprocessor-based modular expandable relays also possess enhanced diagnostic and communications functionality, offering connectivity to communications networks such as DeviceNet, RS232 and RS485.
