Description
The Minotaur MSR33RT/RTP is a microprocessor-based,
monitoring safety relay, with safety-rated, solid state outputs.
The MSR33RT/RTP is designed to operate with dual channel inputs
where one channel is normally closed and the other is normally
open. The Sipha sensors can be connected to the MSR33RT/RTP
inputs.
Test pulses are used to dynamically check the input circuits. All
inputs and outputs are short-circuit protected.
The reset capability of the MSR33RT/RTP allows it to set up for
monitored manual or automatic reset. A start-up test can be enabled
if automatic reset is used. The start-up test requires the inputs to be
cycled before energizing the outputs. The reset and start-up test is
determined by the connection wiring.
The outputs include two 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 MSR30 also has one solid state, normally-open auxiliary output,
which must only be used to indicate status of the MSR33RT/RTP.
