Minotaur MSR122E
Description
The MSR122E is designed to be an expansion relay for use with the
Minotaur safety relays. The MSR122E is typically used in safety
system applications where additional outputs switching connections
are needed to help shut down a manufacturing process, properly and
safely.
The MSR122E can be connected as a single channel (1 N.C.) or dual
channel (2 N.C.) input configuration.
The outputs include 6 normally open safety rated outputs used to
shut down the manufacturing system and 1 normally closed auxiliary
output to indicate the status of the MSR122E. One additional
normally closed output is available to allow the host relay to monitor
the status of the MSR122E. The safety, auxiliary and monitoring
outputs have independent and redundant internal contacts to help
ensure the safety function.
