The MSR338 is an time-delayed output expansion module for the configurable Minotaur MSR300 family of monitoring safety relays. Up to six output modules, 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 MSR338DP output modules can be used in any combination and order also together with the instant modules MSR330P when connected to the MSR300 system. The connecting ribbon cable provides power to the MSR338DP as well as a check on its status. The terminator must be inserted into the final output module. There are three different MSR338P modules, one for each group. In most instances, the output group module is not specific to each application. The exceptions are robot cell applications and logic OR functions which correspond with group three outputs. The MSR338 has three safety rated outputs that work in parallel with the immediate safety outputs of the MSR330P outputs modules. When the output signal from the base unit is de-activated, the outputs of the MSR338 are de-activated after the time delay expires. The time delay is set by connecting jumpers to the wiring terminals. The outputs are three normally open and one normally closed safety rated outputs. The safety outputs have independent and redundant internal contacts to help support the safety function.
