Description
The MSR5T has 1 N.C. single channel input for use with gate
interlocks and emergency stop buttons in lower risk applications.
The MSR5T has output monitoring that can accommodate an
automatic/manual reset function. Automatic/manual reset can use a
jumper or can be used to check operation of the contacts.
The MSR5T has 3 N.O. safety outputs and 1 N.C. auxiliary output.
The safety outputs have independent and redundant internal
contacts to help ensure the safety function. The auxiliary contact is a
nonsafety output intended to provide an external signal about the
status of the safety outputs.
The Minotaur power supply converts either 110V AC or 230V AC to
24V DC. It is intended to be used with an MSR5T or a Ferrotek
noncontact interlock. When used with the MSR5T, the Minotaur
power supply acts like a 110V AC (230V AC) input module allowing a
single channel 110V AC (230V AC) circuit to be wired directly into a
safety circuit.
