Description
The Minotaur MSR38D/DP is a microprocessor-based, monitoring
safety relay, with delayed, safety-rated, solid state outputs.
The inputs of the MSR38D/DP are the same as the MSR30. They
can be connected to gate interlocks, e-stop devices or 4-wire safety
mats. The gate interlocks and e-stops can be either single channel or
dual channel normally-closed circuits.
The reset capability of the MSR38D/DP allows it to set up for
manual or automatic start and restart.
The outputs include two delayed normally-open safety rated outputs
that can be connected to loads up to 2A at 24V DC. These outputs
can be used to send a safety stop signal to a machine or
manufacturing system. The delay is accomplished by the
configuration of jumpers on the terminals. The delay can be easily
adjusted by reconfiguring the jumpers.
The MSR38D/DP also has one solid state normally-closed auxiliary
output, which must only be used to indicate the status of the
MSR38D/DP. The auxiliary output responds immediately to the
change in input status; it is not delayed.
