Specifications
Description
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 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.
