300 Series Configurable Safety Relays

The Guardmaster® MSR310P is a base unit for the MSR300 system. You can combine it with other modules of the MSR300 Series to configure a safety control system with numbers of inputs and outputs, as well as diagnostic and networking capabilities. Up to ten input modules and six output modules can be connected to one base unit. A system can support up to 20 inputs devices and 18 normally open outputs. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past.

The Guardmaster® MSR312P is one of the base units available for the MSR300 system. You can combine it with other modules of the MSR300 Series to configure a safety control system with numbers of inputs and outputs, as well as diagnostic and networking capabilities. Up to ten input modules and six output modules can be connected to one base unit. A system can support up to 20 inputs devices and 18 normally open outputs. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past.

The Guardmaster® MSR320P is an input expansion module for the MSR300 family of monitoring safety relays. Up to ten input modules can be connected to a base unit. The connecting ribbon cable provides power to the MSR320P as well as a check on its status. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past. 

The Guardmaster® MSR329P is an input expansion module for the MSR300 family of monitoring relays. This module monitors the function of connected muting lamps in a system set up for a robot cell application. You can use one muting lamp module—with at least two MSR329P input modules—in each MSR300 system. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past.

The Guardmaster® MSR330P is an output expansion module for the MSR300 family of monitoring safety relays. Up to six output modules and 18 N.O. safety outputs can be connected to one base unit. The six output modules can be used in any combination and order when connected to the MSR300 system. The connecting ribbon cable provides power to the MSR330P as well as a check on its status. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past.

The Guardmaster® MSR338 is a time-delayed output expansion module for the configurable MSR300 family of monitoring safety relays. Up to six output modules can be connected to one base unit. The MSR338DP output modules can be used in any combination and order together with the instant modules MSR330P when connected to the MSR300 system. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past.
