MSR238

The MSR238 is an time-delayed output expansion module for the modular Minotaur MSR200 family of monitoring safety relays. It can be connected to either the MSR210 or MSR211 base unit or to the MSR230output module to provide time-delayed outputs.

Up to 2 output modules of MSR238 can be connected to one base unit by simply removing the terminator, included with each base unit, and connecting the ribbon cables of the neighboring module. The connecting ribbon cable provides power to the MSR238 as well as a check on its status. The terminators must be inserted into the final output module.

The MSR238 has two safety rated outputs that work in parallel with the safety outputs of the base unit. When the output of the base unit is activated, the outputs of the MSR238 are the user-selected time delay expires. The time delay is set by connecting jumpers to the wiring terminals.

The outputs are 2 normally open safety rated outputs. The safety outputs have independent and redundant internal contacts to help ensure the safety function. The delayed normally closed output is an auxiliary signal that must only be used to indicate the status of the MSR238.
