Minotaur MSR18T
Specifications
Description
The Minotaur MSR18T is a monitoring safety relay unit with dual
channel input, 5 safety outputs and 2 auxiliary outputs. It is designed for
operation as E-Stop, safety gate applications, and 2-hand control
applications.
The MSR18T is a versatile unit with extensive diagnostics. It can be
used with E-Stop buttons, gate interlocks, two-hand controls as well
as expansion relays when additional inputs are needed.
When used in a suitably configured circuit, the MSR18T provides
additional safety rated output circuits with checking and monitoring
of its status. Safety critical faults or power failures will cause them to
initiate a lock-out to a safe state.
